GK's V10

I guess it's time to start a thread on this build. I'm building this V10 from 1994 vintage plans that Jacques' daughter sold on ebay last year. No sheets of build notes were included, but hopefully it will be a simple enough build that they won't be all that necessary.

This will be a rowing & sailing version with capability of adding an outboard. Since this is my first attempt at a sailboat, I'm going to tackle the mast, sprit and sail before building the hull. For various reasons, I've decided to use a Bolger 40 sq. ft. leg o' mutton sail plan. The original plan is for a 32 sq. ft. sprit sail and the newer versions list a 35 sq. ft. sail. Following the path of other V10 builders, I wanted to increase sail area, but still want to keep the capability of downsizing to the original plan if I decide I need to store the mast and sprit inside the boat when I win the big lottery and need a dinghy for the yacht. :D With the sail plan I'm going to use, the CE will be within an inch or so of the original, giving me more area without having to worry about relocating the mast step and partner.

Here's a simplified sail plan. Obviously, the hull isn't drawn right, but the basic dimensions are to scale.
Image
The mast will be a little tall initially to allow some adjustments if necessary. Mast is 13'5", sprit boom is going to be just short of 9' long.

Here's the basic dimensions of the sail.
Image
I'll make the first one from polytarp or tyvek and then make a dacron version based on how the starter sail works.

Now for the fun stuff. My mast is made from laminated fir. Finding long enough planks that were suitable was too much of a challenge, so I scarfed together what I could find.
Image
I used 10:1 scarf joints staggered about 2 feet apart.
Image
The scarf joint closest to the mast foot is located in the middle of the laminate. This is it after turning the mast round and 2 coats of epoxy.
Image
Making the square blank into a round mast was fun. I can't think of anything I've ever made that created so much saw/sanding dust. I ripped the square into an octagon on the table saw and then hand planed it to 16 sides. When I made up the 3 layers of the mast, I cut the middle one a few inches shorter to form a clevis when it was all glued up. A hole through the clevis and an eyebolt chucked in my drill gave me a sort of universal joint drive to rotate the mast so I could cut the taper and finish rounding it off. Each end of the mast sat on rubber wheels for support.
Image
Most of the taper was cut with a 40 grit disc on my grinder, then finished off with the belt sander. Here is the last step of sanding while turning the mast. I used a sanding belt turned inside out. The green box on the left is a variac that I used to control the speed of the drill. Around 25 - 30 volts gave me about 50 rpm and that's about as fast as it needed to turn.
Image

The end result is a not quite perfectly round, not quite perfectly straight, 2 3/16" X 13'5" mast that weighs 13 lbs. I'm quite happy with it.

Clever............nicely done, I will watch this quite carefully, I am getting a hankering to build a sailing dinghy.............. if I ever finish the FS17
good luck,

Excellent tutorial on your mast, GK. Great ingenuity, too! I am now hooked on your thread and I'm not even much of a sailor!

Thanks guys. I taught myself the basics of sailing in a BW Squall dinghy on Lake Huron about 30 years ago. That was tons of fun, but I've not been in a sailing dinghy since.
The next step is the sprit boom. I can't decide between a CF wishbone sprit or a straight one out of laminated fir. I guess I'll have to flip a coin to decide that soon. :D

A rope is a rope, unless it's connected to something, then it's a line. Unless that line is a sheet or halyard or something. :doh:
I probably won't depart much from the plans on the hull. It's a small boat and I don't want to complicate it too much. With the wood mast, I'm committed to some bright finished woodwork, so I'll probably go for more of that. 8)

Awright,I realy like that drill with the eyebolt in it for a home made uni joint got a couple of old makita 1/2 drive drills sitting under the shelf in my garage; actuallity I am sorta scared to use them,they are quite powerfull and dont stop as fast as my old 3/8 drill ...sure know what to do with one of them 1/2rs now! wonderfull idea Thanks for the trick Mike R

I know what you mean about stopping that drill. It can be a wrist breaker when a large diameter bit hangs in the material you are drilling. I guess I'd better include this warning: Anyone that wants to try this should firmly anchor the drill and run it slow!!! The little speed control knob on the trigger should be set to dead slow at the start and speed increased gradually. I am lucky to have a variac to do things like this. It gave me good speed control that was easy to adjust. Even then, I had this vision of the mast getting loose and flailing around beating me up. Fortunately, that never happened. :D

OK, my sail is done. It's 100% tyvek cut in one piece from an 8'X10' plain white sheet. I used 2¼" tyvek tape and some outdoor grade polyester thread from WallyWorld on a home sewing machine.
Laying it out. I allowed 1½" to fold over on the edges.
Image

Cut along the line. ¼" nylon boltrope for the luff and double sided tape to hold it and tape the fold down on the edges.

Some more info on the jig for the scarf joints in the mast.
While building my D15, I learned the hard way that I needed to improve my method of joining planks.
Image

A scarfing jig for my router seemed like the best solution. Two parts were needed, a base to clamp to and a sled for the router to ride on.
Image

I used a taper jig for my table saw to cut side rails for the base. It's sized to fit up to a 1×6. I removed the plastic base plate of the router and replaced it with the sled which is simply leftover ¼" meranti with some stiffening cleats around the perimeter.
Image

The end cleats are on the bottom to limit travel of the sled so that the ¾" router bit won't cut into the sides of the base. A few test cuts showed that some shims between the router and sled were needed to get things as square as possible. A couple thicknesses of paper card under one side did the trick.
Image

The end of the base has been relieved to keep the sled supported on the thin end of the cut. The metal spacer keeps the edge of the stock parallel to the tapered base sides. You could use a longer sacrificial wood strip instead of metal. Ordinarily, this would not be used for plywood, but for purposes of illustration this scrap of 9mm is used. In use, I just worked with the planks on sawhorses and clamped the base on each plank with 2 clamps.
Image

Before cutting I set the bit depth to the level of the relieved portion of the base and zero it. Set the stock just to the edge of the relieved area to get a sharp point on the taper. Back the bit depth off and cut no more than an eighth inch depth at a pass and make successive passes until you get back to zero. If you hog the cut, the stock will vibrate too much and start to chip.
Image
That last picture is good enough to show some details in hi-res:

Nice jig, GK and great explanation. I appreciate you posting that. I'll have to build one of those. I really need to start using my routers more. I have 3, a PC with 2 bases, fixed and plunge, an old Craftsman looks like yours that I keep mounted on a table, and a small trim router. For some reason it is always the last tool I turn to, when a lot of times it should be the first. I need to work on that.

That sail looks great. I've never tried making a sail, always relied on Hood and North for that.
A rope is a rope, unless it's connected to something, then it's a line. Unless that line is a sheet or halyard or something.


Not being picky but technically there are only 2 ropes on a sailboat. The rope sewn in the luff of a sail is called a luff rope. The pull cord on a ship's bell is called a bell rope. Anything else in loose lengths are called lines. When they are doing something then they become sheets, halyards, guys, rode or whatever specific to the task. Laying loose in the locker it is always a line. :lol:

I've been working on appendages for the last few weeks. For right now, I've put the kick-up rudder plans on the shelf and made a rudder as drawn on the plans. I reasoned that if my rudder is dragging in a 10' dinghy, I'd just get out and walk. Daggerboard per plans as well. Both are made from a 1×12 radiata pine plank.
Image

The tiller was a great exercise. It's 2 pieces of 9mm and 2 pieces of fir laminated. Both the plywood and the fir are tapered on the sides. The ply was tapered down to about 4mm with a belt sander, then the sanded faces were glued together so that the center plies successively taper to a point. Then I drilled dowel holes and glued 1×3 fir on each side. I roughed the shape on my bandsaw and finished with a lot of belt sanding. It should look interesting after it's bright finished.
Image

I guess it's about time to get some plywood and build a boat for all of this. :oops:

by gk108
Thanks Richard. I almost messed up my daggerboard. My dad came down from Indiana to see his new great-granddaughter last week. I put some parts in my van to show him what I've been doing and left the daggerboard in there all week. That 1×12 didn't like the humidity and it developed a nice warp. It's all dried out and straightened up now, though. The first suitable day that comes along, I'm going to get those parts sealed up. Maybe today.

Richard

Posted: Mon Jan 28, 2008 7:52 am
by gk108
That variac is some of the industrial surplus stuff that we get ahold of sometimes. I got that one and 2 others from vibratory feeders for a machine that inserted glass fuses in the fusebox for some Ford car. That particular variac was a little damaged, so I put it in the green box and added volt and amp meters and use it for bench work. It is handy for things like controlling the temp on my big soldering iron, slowing down the router, etc. Not so good for induction motors like the bandsaw and drill press, as it tends to overheat them.

Thanks, Steve. Plywood is Joubert from eboat. I played with nesting until I got crosseyed and can't come up with anything better than what the plans show. The cosmetics of it are not as serious as the strength and durability factors. V10 has some serious bends at the bow and that's right where one of the bad spots will end up. That gnarly grain turns a lot of open end grain up in the face and I worry about finish and decay resistance there.

I cut the frames and transom today. 8)

Posted: Thu Feb 07, 2008 11:19 pm
by gk108
Got it! I drew out half of the bottom and cut it out, then used it to trace the other side, but didn't cut it. Then I looked at the whole situation for the side panels again and decided I couldn't figure out the original nesting on the plans either. I looked at it a while, got out the full size patterns and put them away again. Then I lined the plywood up end to end and just drew a panel complete. Looked like I had enough room to do it again, so I drew a reference line offset from the long edge and drew another one. It didn't collide with anything I'd already done and the bad spots are now several inches away from anything I'll use. It's still going to be tight and I'm pretty sure the only way this worked is because of the little extra length of the metric plywood.

Stitched :!:
This is why I bought the bendy stuff. It resisted my efforts for several hours, but I studied its movements and decided to put the screws to it. They just go into a 3" cleat hanging loose on the other side. I realized that most of the bend up in the bow is really twist. Tightening the screws provides twist in this area where there isn't much leverage. I left a ¼" gap rather than worry about drawing that little bit in.
Image

Tacked
Image

In some places it's more like filleted with small gaps at stitches.
Image

The plans show a small camber on the bottom of frames 1&2 and I was able to pull most of that in as well. 8)

by ks8
Looking great! Now hold your breath as you snip. :lol:

On my CV16 bow transom, there was an area of such twist, that it would not stay without leaving a few pieces of the twisted stove wire embedded. I don't think anyone ever had that as a problem with a V10 or V12, so happy snipping! 8)

Are you going to flip and fillet and glass the inside before shaping the chines and taping the outside? If so, maybe leave the stitches in until after the flip? Just a thought. :)

Keep those pictures coming!

Posted: Sun Feb 10, 2008 5:30 pm
by gk108
I got faith in the goop. :D It took surprisingly little force from those screws to do the job and a whole lot of the stitches are not very tight. I'll put some lights under it for the chilly overnight and about this time tomorrow I'll cut away.

Outside seams taped.
Image
I used some small pieces of polyethylene poor mans peel ply on the bow and transom corners to tame some of the overlaps. What looks like a gap at the bow is really a reflection of the flash off the plastic. Temp was around 30°F last night, so I put some lights under the hull to keep things warm.

Just as I figured.. a wonderful job..

let us know how that cheap peel works out for you.

Posted: Sat Feb 16, 2008 3:07 am
by gk108
The polyethylene worked good. Pretty much eliminated the need for fill coats where I used it.
I'm stuck big time now, though. I'm trying to use 2 layers of 3/8" ply for the rubrails, but there's a 1.5" camber in the sheer line and I am having trouble getting the plywood strips to bend in 2 different directions at once.
I gave up for the night and went to see my ex second cousin in law's band. For a 16 year old, she can really tear it up. :D

Yesterday I flipped it.
Image
This shows the stand I'm building on. I set the top of the stand at baseline and elevated and spaced the frames referenced to that. After this picture was taken I stripped the stand and replaced the frames with a cradle to hold the hull level.

Then I filleted and taped the seams on the inside.
Image
Today I'll finish cutting the frames and possibly tack them in place.

Well, I got the middle frame and rear frame tacked in place today and started on the two halves of the daggerboard box. Then the wacky weather got in the way. The ground has been staying pretty wet here with the seasonal rain. Today it has rained hard and steady since 10AM. Basically, I'm now on an island. My V10 is on a neighboring island about 50 ft away. If this keeps up, I'll have to go out and drop the anchor on the D15 so it doesn't float away. 8O

Yeah, it's sort of a relief. For me, it's the floating balls of fire ants that are the worst inconvenience right now. I live on one of those celebrated Georgia dirt roads. The county has neglected maintenance on it and one of the neighbors called the road commission and complained. They hauled in 50 truckloads of the finest Georgia red clay they had yesterday. The mush is so deep now that it almost swallowed a car in the middle of the road a while ago. I heard the tow truck and stepped out to see what the commotion was about and that's when I was reminded about the fire ants. :help:
Rain gauge says a little under 4" for the day. The Ochlocknee river is over flood stage right now and won't peak until tomorrow night. I'd work from home tomorrow, but it's payday and I like to be present when the eagle flies. All I need is a good running start to make it to solid roadway, right? :D

good to hear about the rain.. at least I got gravel on my road.. I know how a fresh load and then a good steady rain can make for a nice mess..

Posted: Fri Feb 22, 2008 3:56 pm
by Cracker Larry
Oh yeah, I know that Georgia red clay :help: Hope you have 4WD.

I live on a dirt road also, but I own it and have to maintain it myself. About a mile of it. Lots of fun in this weather, but I can't bitch at the county for not doing it right. Mine is a mess and it's all my fault, according to my wife, who does not like her car to even get dirty.

Posted: Mon Feb 25, 2008 9:05 am
by gk108
Things are getting back to normal now. The road is still a mess, but most of the water has run off.
I worked on small stuff most of the weekend, including some of the components that will be bright finished. I roughed in the mast step which will have a solid mahogany cap on it.
Image
The mast partner and transom knees will also be solid mahogany, bright finished.

Here's the beginnings of the backing block for the bow eye.
Image
This shows the 2 pilot holes and a dowel to aid in alignment. When it's time to put it in place, I'll use a method described by Evan using epoxy putty and a couple of spots of hot glue. When it's all set up I should be able to just run my drill through the holes in the block and they should guide the bit straight out the front. At least that's how it worked on my D15.

Also cut the transom doubler.
Image
Most of this is being done while the daggerboard box is getting prepared to install. This week I'll finish taping the frames and install the DB box before anything else gets glued in so it will still be relatively light for the next flip.

by gk108
Thanks Dave. One more coat of graphite on the inside of the daggerboard box and I'll stick it together.
While I've been coating the DB box, I've also been putting graphite on a couple of other places like the mast step.
Image
I gave the top of it a coat of neat resin, then masked the whole thing after that cured. I don't want messy black stuff complicating the bright finish. I took an x-acto knife and trimmed the masking tape around the hole, then routed a roundover on the edge of the hole. That also trimmed the masking tape so the graphite covers the radius in a neat fashion. At least that's what I hope will happen.

Posted: Thu Feb 28, 2008 9:53 pm
by gk108
More fun with graphite.
Image
The pivot holes for the tiller were drilled oversize, masked and filled with fiberglass, graphite and epoxy. I did this by priming the hole with neat epoxy, then wrapping a strip of glass mat around a dowel and dipping it in graphite epoxy and stuffing it in the hole. The dowel slid back out, leaving the glass in the hole and I topped it off with graphite epoxy. After it cured, I filed most of it down flush, removed the masking along with the rest of the excess and this is the result. Now all I have to do is ring the center of the previous hole with my drill.

And the real reason for playing with graphite this early in the build.
Image
The insides of the daggerboard box are fully coated with graphite and the two halves are ready to glue together. I still have to wrap my head around the idea of cutting a big hole in the bottom of my boat, but I'm about to be ready for that.
Also shown are a couple of rings for the access hatches planned for the bulkhead.

Posted: Sun Mar 02, 2008 8:54 am
by gk108
I put in a full day of it Saturday. I got the daggerboard box glued together and used it to mark the location of the hole in the hull. Then I drilled guide holes in the corners to transfer the lines to the other side of the hull.
Image

Then I flipped the hull and connected the dots.
Image

And cut a big hole in a perfectly good hull.
Image

Then I cleaned up the hole with a rasp to make sure the box fit.
Image

Then flipped the hull upright again and levelled it and aligned the box and glued and tabbed it in place.
Image

This much of the box hangs out of the bottom and must be trimmed flush with the hull.
Image

And naturally, the best looking seam in the whole boat is the one I cut out.
Image

I have a few more things to do while it's upright, but the next major step is flipping the hull again, trimming the excess box and fairing and painting the bottom.

Looking into the future here.
I hope to have a bright finished foredeck made from Chinese okoume. Right now, it looks like it could turn out about like I want.
Image
It's only 5mm thick, so I'll have to laminate it to something. I'll top it with some of the surfboard fiberglass. If my seam in the middle looks too bad I can always glue a strip of mahogany on top. :D

Between the spells of bad weather I got a little accomplished. I worked on the skeg and got it on and taped in place. The last long cuts I made with my bandsaw indicated that the blade guides needed some work, so I got that out of the way on a rainy night. Nothing really exciting about it, so no pics of it right now.
I knew I would have some leftover goop from gluing the skeg to the hull, so I decided to use it for a little pad on the outside of the bow eye. I needed some kind of mold to make the putty hold the desired shape while it cured. The angle where the side panels meet at the bow is close to 90° so I used some 45° cuts on styrofoam to make the mold. They were hot-glued in place and a strip of tape stuck across the bottom to hold the putty. Here it is with the putty in place.
Image

After that all cured, I broke the foam away and cleaned it up so it looked like this.
Image

A little time with a rasp and sandpaper to get to the final shape and drill the holes the rest of the way through and this is the result.
Image

As you can see, I also put a layer of blended filler down to fill the weave of the biax tape before I glass the bottom. Also barely visible in that last picture is the fillet on the underside of the rubrail.
So far, I've done nothing to the transom since it was taped on. I guess I'll spend some time on that this week. :D

Posted: Fri Mar 14, 2008 9:05 am
by gk108
After a couple of rounds of blended filler to fill the tape weave, I cut some 4 oz. woven fiberglass to cover the bottom and 5" up from the chines.
Image
Then I used a foam roller to apply the resin. It worked great and according to my calculations, the glass to resin ratio is real close to 50/50.
Image
This gives you an idea of how much work it was to fill the 6 oz. biax tape. You can also tell that I was playing with the white pigment last night. :D

Posted: Sun Mar 16, 2008 7:02 pm
by gk108
Fairing is done and a coat of slightly pigmented resin has been applied overall.

Thanks. It took a little extra effort to fill the 6 oz biax, but feathering the edges was quite painless. Most of the filling was done with BBC blended filler and it is easier to work with than the WEST product. I bought the small size Quick Fair kit and when it came I thought I might have been too optimistic about how much I needed. I used some over the weekend, mostly for the short cycle time, because there's always a few spots that you miss somehow. Right now I've got the same situation as Larry, a guide coat of pine tree pollen on everything. No time to try painting anything. :?

I love the detail of your report. I'll be watching this thread with interest, and probably re-reading it a few times to get all the details. Keep it coming. :D

I'm collecting materials and planning a build of the V12 in mid-April when my brother and father are coming down to help. We'll have four full days to make a great start. Then I'll be left alone to finish it.

the pigment in the last coat is good idea - it helps give contrast when sanding the primer.

Thanks.
Joel, that's sort of what I was hoping for. It should work well with the gray primer. The other benefit is that I could monitor coverage of that coat a lot better. Didn't miss any spots and had no runs. :D

Shaun, take your time stitching the bow and remember that it is as much of a twist in that part of the bottom panels as it is a bend. :wink:

mecreature, it will be S3 white on the outside, rear seat and mid seat. Hull inside will be light gray. I'm sure things will slow down when I flip it back over. Gotta be extra careful with all this brightwork I've gotten myself into.

I spent last night covering the daggerboard and rudder with some 3¼ oz woven cloth. Since both of those parts were made from a single plank of pine, I thought it would be a good idea to help control splitting and warping. If they keep looking good they will be mostly bright finished with graphite on the leading edges.

1 coat of primer applied with roller and sanded.
Image
No drastic flaws or anything. It sanded really easily after 24 hrs. Before that, the paper loaded up and clogged. One thing I learned is that the blue paper shop towels are not the thing to use when wiping the hull down with alcohol before painting. They leave a lot of paper lint on the surface. I had to wipe it down a second time using an old T shirt.

Second coat of primer applied with roller.

It was a little warmer when this coat was applied so I thinned the primer about 10%. I'm happy with the results. :D

That's the new Yacht Primer. It's really light gray. It's nice. I'll probably never use another primer for a boat.
It got too cold to do much last night, but the primer is sanded down the middle so I could layout and mask where the graphite goes.

Gk you do some nice work! Can't wait to see it painted. Im planning on building the same boat on my next project. Looking at your tread makes me want to build one. I've never sailed before only powerboats but was always kinda curious to try it out. Figure a boat like this if i can't sail it my little 2hp honda will push it around :wink:. Keep up the good work and nice tread very informative.

Thanks Jay. For right now, I'm not planning on a motor. I'll build it to be capable in case a motor happens to jump in front of me, but I want to keep it unregistered at first.
Slow progress this week. I had to finish preparing the daggerboard and rudder so they could get some graphite on their leading edges at the same time I did the strip on the hull. I finally got two coats of graphite on today and will do the last one tomorrow. And touch up a few worn spots on the D15. :oops:
Then it's on to the white paint. :D

How did the spraying go.

so far I have only roll and tipped.. which make tight spots kind of a pain. Seems spraying would help a ton and probably use less paint.

I cant wait to see how the clear goes.. should look sweet over that Orca white

Posted: Thu May 08, 2008 10:07 am

It sprayed pretty easy. The last coat would have been a keeper, except I listened to the weather foreguesser. It rained continuously after I sprayed it on and I got a dull finish that took too long to set, so it sagged in a few places.
I'm going to go for roll and tip with the clear. I think I can do it if I can get my plan of action right and the weather cooperates. I'm more than ready to move on from this painting stuff for a while.

Thanks, Larry. The S3 clear is pretty easy to work with. I tried to take all the tips on S3 and work them into my procedure. A while back TomW posted some info on the use of S3 clear that convinced me to try it. Had to go to Crystal River and let cottontop show me what is possible. Joel's advice on building up coats and sanding, then applying the final coat was the key to it all.
I just hope the orca white and graphite black on the hull and appendages doesn't look too much like a fat killer whale. Don't want any great whites getting any ideas. :help:

I think JimW has a history of good finishes. :D
Over a neutral color, the clear doesn't have the same sense of depth that it does on something like he has. The real reason I bought the clear was for some bright finish adventures.
Jbo, we can make it happen. Sooner or later, I'm going to take the D15 up to Newton and do some exploring. I wouldn't mind getting a look at your Thompson, too. 8)

I could meet in Newton easy. Fishing the Flint from Warwick to Albany in my canoe Saturday, hope to catch my first shoalie(s).

I've got my old 18 on the Thompson right now while I look for a semi-period-correct motor in 35 or 40 horse model. If you see a good looking 35-40 horse "JohnsonRude" in the '65-74 year range for sale, let me know. It'll be a little under powered until, but I'll be patient.

Gotta figure out some way to get a windshield too. Nobody here wants to bother with it. Was gonna make my own, but I read the other thread about doing it on your own and wasn't very encouraged. It'll ride fine without it, but I'd really like to have one.

Sorry about the mini hi-jack.

Bellamy said nothing doing on the motor unless I want to start a complete rebuild. I'm more along the line of new points, coils, wires, carb rebuild, impeller, crank, go. Think I have a good line on a '63 40 horse in north Georgia, just trying to figure out how to evaluate from here. Got a "guy" who'll do it for me, but if something gets missed, I'd rather it be me that made the bad call than him.

Bellamy said come pick a windshield for free, but be prepared to take the boat under it too. Got to find out what it costs to drop a boat at the dump. :roll: - and the windshield won't be the "right" one. If I decide to repaint, it won't matter. I'll pick one, fill the original holes, and make it fit.

Jbo


PS What is that boat?

Posted: Thu May 15, 2008 10:52 pm
by gk108
That's an '82 Glastron that I hauled off for the trailer. Aside from a few bolts, the windshield and 3 aluminum corner castings are all that I saved. The rest of it was waaaay too far gone to consider a rebuild. I dismantled it and used a sawzall to cut it into parts small enough to fit in a dumpster. Hauled the pieces to the county dumpsters by the river for no charge. :D

The motor stuff sounds just like Bellamy. "It won't be cheap and you'll have to wait your turn" was the response to my inquiry about the 9.9 on my D15. I told him that's just what I wanted to hear. He went deeper into that motor than most people would and so far the results are great. It only took 5 months for my turn. :roll:

While I'm waiting for the paint to cure, I've been laminating a blank for my foredeck insert.

I'm being extra careful, Tom. Decorative woodwork and bright finishes are unfamiliar territory for me.
I finally had to use my longboard today to clean up the top of the rubrail. Then I made a bunch of cleats and glued them in along with the rings for the "hatches".
Image

Then I laid out and drilled the holes for the gudgeons in the transom doubler and glued it in place.
Image
Those holes will act as guide holes to drill on through the transom. I'm going to try some more bright finish back here, so a little masking tape to keep the glue off the edges and out of the holes for now.

Then I spent the rest of the evening working on the final fit of the foredeck. It's not quite there yet, but real close.

Posted: Sun May 18, 2008 9:53 pm
by gk108
Lots of good progress today.
When I got on the job project security was already conducting some kind of covert operation. Not sure what it was all about but apparently it involved rapelling down a rope while looking like a rope.
Image

Next on the agenda is more stuff around the front frame. I wanted a drain in the mast step so I cut a groove in the bottom wide enough for some ¼" poly tubing.
Image

Next I filled the groove with putty and pressed the tubing into it and taped the end to hold it in place. Then I mixed up a big batch of goop and made the bed for the step. There are 2 smaller pieces not shown that are the bottom layer and a filler below it. I laid the filler piece in and built up level around it with putty, then laid a strip of biax across the top of it running from chine to chine. On top of that went the piece that is the actual bottom of the hole, then the assembly pictured above.
Image
When it is cured I should be able to pull the tubing out and have a nice little drain.

While that was curing, I moved to the mast partner. It is solid mahogany 1"X7¾". I cut it roughly to length on the band saw, then rabbetted the front edge with a dado so that it barely overlaps the seam where the foredeck meets the front frame. That meant I had to cut a rabbett on the sides as well. It's curved and on an angle. It was tedious, but now everything will lock together.
Image

This is it from the front. Now I'm forced to figure out a pretty way of dealing with that gap at the edge of the rubrail.

Image
just lay plastic wrap over the rubrail, two layers, secure it with masking tape for a tight fit. Then blob on some wood flour blend and press the partner into it, and wipe reasonably clean. When it cures, simply pop it off the plastic wrap and clean it up. If you want it purdier than that, you could add a thin mahog veneer on the forward face of the partner, or some other bright finished wood.

Or, you could figure the angles and do some woodworking. One cost time, the other, materials. I'll be doing this (plastic wrap and blob) on the bottom of some of my removeable floors, to get a perfect fit to the changing shape of the bottom panels inside the cockpit.

Thanks Huck. Are you still thinking about the FL26?

I've made a little more progress. I have the oarlock sockets rough cut, Not sure which way to orient the grain. :doh:
Image

Then I moved to the transom. With guide holes drilled in the doubler, I still needed to fillet and tape the bottom without filling the holes back in. Before filleting, I rolled up some strips of poly and put them in the holes, then filleted and taped. While the epoxy was still green, I used a utility knife to cut the glass, then after full cure, opened up the holes and pulled out the poly.
Image

After looking at it, I started to worry that I had made the holes too close to the bottom, so a trial fit of the rudder was necessary.
Image

About as close to the bottom as it can get, but right about where I wanted it.
Image

Another look from below.
Image

Since that fit OK, it's time to put some rear seat cleats in. These were cut on an angle to match the transom. That made alignment a lot easier, since the top of the cleat was level.
Image

I still have to put some cleats on the sides, then It's time to measure for the seats. :D

Seat tops are cut out and dry fitted. I made cardboard templates first, then transferred that to plywood. Most of the pigmented resin has been applied to the inside of the front and rear compartments.

Posted: Tue May 27, 2008 11:15 am

I found some ¾" stock on ebay that was conveniently cut to the length that I wanted. I had those 6 pieces planed down to ½" to save a bit of weight. I have a few more for various bits of trim. I may have to steam bend something. 8)

On the pigmented epoxy, it's not suitable for direct exposure to the sun. It's a nice alternative to plain coated interiors of compartments, but definitely not an aesthetic alternative to paint. On horizontal surfaces it looks decent, but as with all epoxy, it's hard to control runs on vertical surfaces. Especially in areas with features like cleats.

Wow, that is pretty low for that gudgeon. I did a few holes that close to a corner too. I had to grind away just a little of the final cosmetic fairing (fillet) to get the flat backing washer to fit. Looks like you may need to do the same if you fair a final fillet there.

edit - And there were a few washers I had to grind one edge of just a bit so a structural fillet would have right of way.

Looking good! :)

There will be some very strong similarities to his hatch system on my little oval holes in the front.

ks8, I'm on a scavenger hunt for a small scrap of SS to possibly use instead of washers for the gudgeons. While test fitting the rudder, it looked like there is enough flat spot to work with.

Progress!
The rear seat is in place and I spent Saturday making knees.
Image

A coat of resin sure brings out some color. I made some flour from the offcuts of the knees. The fillets here have a 50/50 mix of pine and mahogany flour. A little dark, but not bad.
Image
Note masking tape on the gudgeon holes to prevent mud daubers from building nests.

Both the transom and the doubler are meranti. The doubler is a left over piece of ½" from the D15. A nice range of colors for a bright finish.

The next step is to glue the knees and foredeck in place.

I need to do something there. The plans call for a sweeping arc on the seat tops that provide stiffness to the sides in that area. What I'm going to try is a gusset that will hopefully do that and provide support for the middle of the seat as well. It's looking like those seats will be the last parts to be built.

gk 108,

Your picture of the knees opened my eyes to possibilities for clamping my breasthook pattern. Ponder long enough and sometimes someone else comes up with a solution. Drilling a clamping hole is a real good idea, I've done it on other projects but not recently and sometimes I suffer from C.R.S. Also, clamping the piece of scrap ply to the rubrail will assure the proper angle. I like it, thanks again.

Posted: Thu Jun 05, 2008 9:37 am

Glad I could help, Don. I was having the same kind of mental block about trimming the foredeck with something to cover the seams at the edges. Some sort of cap on the rubrail that is almost tall enough to call a toe rail. Then Wobblylegs posted pictures of his toe rail and I had a similar epiphany. We often need a catalyst to make things gel, just like the epoxy. 8)

Thanks guys. I'm wondering how it will turn out, myself. :D

I glued the knees in last night. Tonight I worked on the little filler pieces between the knees and the doubler.
Image

Looking down from the top, you can see the little notch cut in the knee to receive the filler. I figured I would get a better fit if I waited until they were glued on the make the notches.
Image

I'll glue the fillers in later along with some plywood strips along the sides for inwales. I bought a Taco rubrail kit and I need another layer of ¼" to get enough thickness for the length of the screws. Meanwhile, I found this old comic book...
Image

Posted: Wed Jun 11, 2008 11:22 am
by gk108
I had to back up a little bit before moving forward. Those fillers on the transom didn't look right somehow. I made another pair that are wider and glued them on. After everything sets up good, I'll blend them in to the knees and dress the tops flush.
Image

Next I tackled the oarlock sockets. I made a jig from scrap wood to drill dowel holes and marked the drill bit for depth.
Image

Then it was on to the strips to make the rubrail thicker.
Image

These have a 45° bevel cut on the bottom edge. With the 45° bevel on the butt blocks it has a nice mitered look.

Yup. Those little details are what slows me down. I tabbed the knees on the bottom side and cut limber holes in the mid frame. Then, I did a lot of trimming and sanding. Somewhere along the line, the skies cleared enough for me to get outside and finish preparing the mast partner. It's about ready to glue on the boat. I have developed a plan to deal with those gaps where the partner meets the rubrail. It's a ridiculous, time consuming plan, but, it's a plan. With luck, there won't be any exposed end-grain on the partner.

After the partner is on, there's a round of QF to do on the inside, then glue the mid seat in and paint. Sounds simple, right? :D

Mast Partner Part 1 (of 4???)
Underside of partner precoated and sanded around the edges with 60 grit and glued in place with a pretty fillet.
Image

Front edge of partner masked to protect deck finish and a very thin fillet applied.
Image

After that set up for an hour, 9 oz woven tape was applied over the fillets on the underside.
Image

I lightly brushed some neat epoxy over the small fillet before removing the masking tape.

Notice the ends are still rough cut. Part 2 will require some crazy router work. :lol:

Mast Partner Part 2a

Trimming the ends.
First, using a flush cutting router bit, the end is trimmed flush with the rubrail corner.
Image

Then, using a rabbeting bit, a ¼" offset is cut along the bottom edge of the end.
Image

Next, using the ¼" offset as a guide, the end is trimmed again with the flush cutting bit, leaving the end of the partner ¼" in from the edge of the rubrail corner.
Image

Part 2 will be continued as soon as I fix the dead power switch in my router. :?

I guess it's more time to work, because there is certainly room for me to get better. :oops:

All of the intended brightwork is Honduran Mahogany. In fact, the only parts not made of mahogany are the cleats and DB box ends. Those are Cypress. 8)

Partner Part 2b

Here we see the reason why I need to get better. After fixing the router, I finished the cuts I was on and managed to break chips off of the corner where I didn't need to. The solution was easy enough, except for finding the chips in the pile. :help:
Image

A little plastic to hold it there while it cures.
Image

And we're ready to go again. Components for part 3 are already slightly steam bent.
Image

I'll have a nice, clean edge to work with.

Mast Partner Part 3

I made the blanks for the end pieces a good bit oversize to start with so I had room to play. The bottom edges were beveled to match the angle of the rubrail, then the top was planed down to a height just above the partner. While doing this, I tried a few different clamping schemes.
Image

After trimming, I settled on this method to clamp. Basically, I clamped cleats to the partner, then pulled against them. After filling the remaining gaps under the ends with putty, the pieces were glued on and left to cure.
Image

When cured, the remaining excess height and thickness was planed down and sanded smooth. The ends were cut flush and cleaned up with a chisel.
Image

A little router work and some sanding and all the sharp corners are gone.
Image

Just a little more cleanup and it will be ready to seal and finish.

Hey Tom. Things have been busy around here. My boss finally came by a few times and completed the rebuild we started about 3 years ago. I took the D15 as a chase boat and we got it wet in Lake Miccosukee.
Image
We're girding our loins to do battle against the scallops this year. I have to stop working on the V10 long enough to come up with some kind of temp sunshade.
One Sunday afternoon, it was way too hot to do any boatbuilding, so I had to take her to go cool off in Wacissa. As is often the case, I wasn't the only one there with a homebuilt boat. Here's Elsie Mae, a cypress strip canoe.
Image
These two said the boat works properly because they caught a 6 lb bass in it already. :D

Shaun, tell your brother that he will be happier that he didn't sacrifice speed for beauty. That applies to build time as well as on the water. I'm just guessing here, but your boat is probably going to weigh nearly the same as mine, even though it's 2 feet longer. With my leg o mutton sail, I might be able to sail closer to the wind, but that alone probably won't make up enough difference to win the race. I'd have to get some new-fangled keel designed in the Southern Hemisphere, I guess. :doh:

Where are Miccosukee and Wacissa?

Jbo

Posted: Thu Jun 19, 2008 9:28 am
by gk108
They are both south of here.
Miccosukee is a fair sized lake, but about 80% is too choked up with weeds to get to. Good fishing and duck hunting. It's about the closest place to put in any decent sized power boat. Take Metcalfe Rd south from T'ville. A few miles after you cross into FL, you get to the town of Miccosukee. Turn left at the store and follow the pavement to Reeves Landing and the fish camp.

Wacissa is further away in the same direction. Metcalfe Rd turns into SR59 in FL. SR59 hits US90 and jogs east a few miles, then breaks off south again, crossing I-10 and US27. After you get to the town of Wacissa, SR59 turns west, but if you continue straight for a mile, you hit the river. Some excellent canoe and kayak waters. The river has some problems with weeds choking it, but has enough traffic to keep most of it clean. The riverbed is peppered with spring vents and blue holes and the water is always as clear as the picture above. It's one of the few really natural places like it in the state. Highly recommended. The only disturbing thing down there is the airboat traffic, but high fuel prices seem to have made them reduce their running time.

gk,

Not commented on your thread before (don't visit this section often) but have been watching occasionally. Very nice work, and "Mast Partner Part 2a" will be filed for future reference. Dunno what for, but it's a nice way of trimming ends. One day I'll let you know if I copied you :lol:

Thanks, Tim. I pondered over this stage of the build for a long time. I've been a little nervous about the whole thing because I've never done much of this kind of stuff and it's an expensive piece of wood. Please copy away. Stay tuned and you'll see the trim that your toe rail inspired. 8)

With a great sigh of relief...
Mast Partner Part 4

About the easiest step. Roll on some resin to seal it.

And if you look close, you can see where I glued those chips back in place. That seems to have been a good enough fix.

I worked on making trim to cover the seam where the foredeck meets the hull. I did a lot of pondering on this and no obviously simple solution came to mind. I was stuck on the idea that whatever I did had to cover the full width of the rubrail up there and something that wide would never bend to the contour of the hull. Then Wobblylegs posted this picture of his toe rail.
Image
I had a :idea: moment when I realized that it didn't need to cover the whole rubrail. I already had a rough idea for the cross-section of the pieces, so I cut out two of them. Somewhere in the background noise that little voice told me that I should cut an extra one since I don't know what I'm doing, but I ignored it. :|
I made a crude steam box using a wood fired camp stove and a 5 gal metal bucket with a lid.
Image
It worked pretty good and the first piece bent right to the lines. That filled me with too much confidence, I guess. I forced the second one too hard, too fast and it broke in two, so I went ahead and made that third piece. :roll: Here's the broken one, a finished one and one cooling under the clamps.
Image
The finished one barely looks bent compared to the one under the clamps. After they cooled, they still sprung back a good bit, but that was considered when I laid out the curves. They ended up pretty close to the right shape.
Image
The idea is to overlap the seam and lay flush with the deck. A fillet will cover the gap on the outside. I drilled holes along the rubrail where I wanted the outside edge to land and inserted nails to locate against. Clamping pressure pulled it all into place.
Image
The wood I'm using for these is from the same batch that my cockpit seats will be made from. It is very much darker than the deck, partner and knees.

The one that hasn't been glued on yet has relaxed back to nearly straight during the overnight. I'm going to torture it on the rack for the day and try to get it glued on tonight.
I think maybe I'll try to avoid stem bending in the future. Those two little pieces of wood sure are going to consume a lot of time compared to other parts that size.

Not much progress the past few days because of weather and other things. The other strip of trim is in place. I ended up using a heat gun to get the final shape on it. After I cleaned up my sloppy glue job, I worked on the last detail for the bow. A pad for the cleat. It's not glued in yet and may be subject to minor changes.

Thanks, guys. It does look good with a coat of resin on it. Very dark wood. No pictures yet, though. I glued that last piece on the bow and added a little more putty to the outside fillet and sanded to the profile I wanted. Then I drilled oversize holes for the bow cleat and filled them and coated the dark wood with resin to seal. It's all sanded now, ready for another coat of resin. I'll see if I can get a good picture of it after that. 8)

I haven't made it there yet. I've been trying to get the rest of the boat up to the same point of finish as the front. Some parts don't even have the first coat of resin on them yet.

I have a blank made for the starboard cockpit seat. Here it is after a little cleanup.
Image
It still needs the outside edge cut to the contour of the hull, then some support for the middle needs to be made.

While that was curing, I spread some QF around the rear seat area and sanded that down. Also finished tabbing the middle seat to the hull.

Yeah, Tom. It looks like I'm going to have to take a little break, anyway. I have a chance to go stay on the Wakulla River for the rest of the week. 8)
Maybe I'll get to see how suitable the D15 is for scalloping.

I'm not absolutely sure, but I think I have the last parts glued to the hull. Here's the middle support for the starboard cockpit seat, viewed from below.
Image
I wrapped each seat with a little packing tape in case it got sloppy under there, then clamped the support to the seat and hung it in place while the glue cures. These will also be tabbed to the hull with 9 oz woven.

A few scrapes on the paint. The dock really had no provisions for mooring a boat and we had 2 and an aluminum canoe. The daily storms tended to blow them around at the dock. It was a great place to stay in a steamy, early morning Tarzan movie set kind of way. The Florida jungle that I love. A little too far up the river for serious scalloping in small boats, though. 25 miles round trip and a bunch of it is manatee zone. We may make another run from the ramp at St. Marks on Thursday. 8)

Finished with the Quick Fair on the inside. Weather, scallop season and a side project have impeded progress. The side project is the 4X10" bass guitar speaker cabinet in the background.
Image

Since the last rounds of sanding may have exposed some bare wood, I'm going to roll a coat of resin on the inside of the boat , then it's on to the primer.

I guess any kind of bright finish on my plywood seat tops is out of the question now. There was a good bit of open grain on the face veneeers and I filled it with QF to keep the wood from misbehaving. Notice all the white spots where the open grain is.
Image
Still, this meranti is really a lot denser and somewhat heavier than what I got for the D15. Good qualities to have for frames and transoms and stuff.

Yep... seal it up. Getting close! At least there won't be the severe checking problems associated with DFir. You might even be able to fill those sorts of openings with straight epoxy, just as it is getting cooler, to minimize air bubbles from wood venting (for the future)... and you could always put your own thin veneer on there for bright work, later, if you really like the idea. It wouldn't weigh that much on the seat tops only. If it doesn't get too hot, bright work could look very nice there. Pick a light colored species for a veneer?

Have you got any baffle or port system planned for the spkr cabinet? 8)

Posted: Sun Aug 03, 2008 9:33 am

It's sealed on the inside and the foredeck got its final coat of resin.
Image

I'm really happy with the way the dark trim looks.
Image

Image

I rolled most of this coat on with a foam roller, but on the foredeck area, I switched to this fur roller:
Image
It did a real nice job of laying down a smooth, thin coat with none of the bubbles that you get with a foam roller, but it shed a lot of fur and left bugs on the finish. You can see some on the partner in this picture:
Image
Hopefully, they will sand off when I prep for the clear LPU.

And the speaker got a coat of resin on the outside to toughen it up. As you can see, it has a 6" X 6" round vent on the rear of the cabinet. It's a copy of a PV box that seems to be popular. I'll load it with Eminence BP102 drivers, so it should shake 'em up when it's done. :D

Well placed brightwork is a wonderful thing. :)

Those fuzz bugs will lessen after sanding, but they may not go completely away.

I've been thinking of trying the very short fiber nylon brushes, the flat pads, that some use for applying epoxy paint to a garage floor. I'm wondering if they would minimize bubbles, ridges, and fuzz bugs. Of course I'm running out of unfinished area... but that seems like a good thing!

What about a veneer on the seat tops of the same species that you have on the foredeck? :)

Cabinet is looking good too! Are you keeping its interior smooth and reflective for the highs, or padding it?

Gary, have you tried a Thermacell to keep the bugs away? They work better than anything else I've seen. They even keep mosquitoes off my wife to her satisfaction. A lofty goal in the GA swamps :lol:

Posted: Sun Aug 03, 2008 10:27 pm
by gk108
Larry, I keep forgetting to pick one up. The boss's wife packed a small one on the Wakulla River trip, but we never needed it. She highly recommended it, too. I have to do something because insects that are drawn to the light really limit what I can do at this stage. Yesterday was a good example. I wanted the epoxy to be tack free by sundown, so anything that might land at night wouldn't leave marks. With this last coat, I wanted to make sure that anything sanded through to bare wood got covered again. Applying the resin too early meant that the plywood would still be heating up and outgassing and the bare spots made themselves quite evident by blowing bubbles in the fresh resin. That's when I took a break for a while before switching to the fur roller. After I did the foredeck in that second session, the areas that bubbled got another last coat. Finished right before sundown, killed the lights and hoped for the best. :?

I picked at the big fuzz bugs today and they sort of pulled out of the epoxy intact. They may not be too much of a problem. The idea is to have enough dried saltwater on there to hide that stuff, anyway. If that doesn't do it, I'll spec an extra long snotter and leave the excess laying up there to confuse the eye. :lol:

Never let anyone tell you that 'sweat equity' in your boat is not a tangible thing. It looks like this:

A little bit of progress.
I got this thing done and out of the way Saturday.
Image
No power rating, just a warning; don't clip your 1000W amp. It got the full treatment, internal bracing between front & back, Penn hardware, Neutrik connectors and yes, stuffing, literally. I used surplus polyester batting from a local ladies undergarment factory that closed a few years ago. :D

Now for the important stuff.
I sanded the bugs off of the foredeck and partner and gave them another coat, this time with a good old foam roller. That turned out real nice, just needs a light pass with 320 grit before the S3 clear.
Right now I'm working on the cockpit seats. The mounting points are all in place.
Image

The seats are shaped and the corners rounded.
Image

I'm a bit undecided about the exact method of fastening these seats to the mounts. They need to be removable for easy refinishing, but they need to help provide resistance to oilcanning in that part of the hull. Those are inch thick cypress cleats on the mounts, so a wood screw will work, but would a machine screw with a nut & washer be better? Or a tee nut? Things to ponder while I sand all those little slots. :?

Posted: Mon Aug 18, 2008 9:49 am

A little progress report, though progress might not be the right word, since I had to back up a bit.
I've been trying to make absolutely certain that all surfaces are well sealed. While doing that I noticed things like a little QF slopped on the mast step where it will have a bright finish. Got that scraped off, but exposed bare wood doing it. It got another pair of last coats.
Stood on my head while prepping the area under the mid seat for priming and noticed a couple of fillets that were defective, so they had to be done again.
The bottom panels just behind the mid frame are giving me a hard time as well. They have some areas that just kept sucking up resin and wouldn't seal. Those areas got their 5th coat last night and I think they are finally sealed. No telltale pock marks from the resin running back in the vents as the plywood cooled overnight.
The cockpit seats are sealed up and ready to move on to their next step. The daggerboard is finally completely sealed as well. The entire blade is covered with surfboard glass and sealed, but the end grain of the NZ pine plank got opened up when I cleaned up after gluing the mahogany stops on the top. I used my heat gun to warm the blade about 4" below the top, then brushed resin on the top and stops. At the same time I was coating the cockpit seats, so I could just turn around and brush more resin on that end grain as it soaked in. I know I hit it 5 times and it still looked dry when it cured. Here it is after the final coat of resin.
Image
I'm getting real close to breaking out the primer. Gotta see what this weather is going to do. :doh:

Already restocked the sandpaper. I'm sure the scalloping is poor around St. Marks right now. My boss was making moves toward getting a houseboat that is (was?) tied up there, so we would have a base to operate from. He heard from the owner last Thursday and she said she removed her valuables and the shore power in preparation for the storm. My guess is that it either sank at its dock or broke loose. Either fate is OK by me. "You know who" wasn't looking forward to the prospect of dealing with the issues that a 39 yr old houseboat might have. :help:

Well, wouldn't you know, I guessed wrong. The houseboat made it through the storm OK, sort of. We rode down to St. Marks this afternoon and looked it over.

I haven't done a whole lot on this boat lately. It took a little while to get cleaned up and dried out from the 27" of rain that TS Fay dropped on us.
I bought a bunch of fine quality silicon bronze fasteners from boltdepot.com to mount hardware with. Lots of little holes to layout and drill. Here's one of my favorite tools, an adjustable drill/countersink for #10 wood screws. The collar will also adjust to drill deep enough for a plug over the screw head. It saves time, but the 18 holes for mounting the cockpit seats still took over 2 hours to complete.

Yeah, I have the posture of a question mark for about 2 hours after I get through painting under the seats. :oops:
I applied two coats of primer to everything inside and the rubrails in a series of 6 - 5 oz batches. That took a whole quart.
There are a couple of places on the brightwork that need another last coat of resin, so I'll get that in a day or two, then sand the primer and probably use up the last of my QF before applying the last coats of primer.

This round of sanding is over. There were several rough spots that needed some more QF to fill.
This picture shows the high spots really well. Note the slightly different colored QF along the lower frame fillet.

This area at the rear frame still looks bad. One more application of QF should do the trick.
Image

This area of the chine seam is looking good after a little layer of QF over the primer.

I've decided the final pattern for the two colors that I'm going to use for the topcoat. The gray Kiwi Grip is very close to Bainbridge White, so I'm going to stick with factory colors and not try to add any tint to the Bainbridge White to darken it.

Top coats under way. At around 11PM I started with the rubrail in Orcas White. It's masked on the outside at the bottom of the rubrail, but I didn't mask most of the inside where the Bainbridge White will go. Two coats are brushed on so far. The first coat went on OK, looked like crap, but it was only the first coat. This is the second coat applied around dawn this morning.

Thanks for the encouragement, Larry. The third coat has really gone on nice. I switched to the whizz roller and foam brush for the rest of the way.

Heavy rain yesterday prevented progress, but I got the fourth coat on the rubrails this morning. With a 24 hour interval between coats, I had to scuff the surface with a scotchbright pad. One more coat should do it. Hopefully, I can get that put on this evening. I have a 5 band rock show to produce on Saturday, so the rest of my week is about shot. By the time I get back to it, the paint should be cured enough to allow masking for the next color. 8)

Yes, I found the same thing. The whizz rollers are easy to clean and you can reuse them many times with S3 paint.

Rubrails are painted, seat tops need another coat or two. I never have been good at guesstimating the amount of paint I need. Rubrails on this boat require enough paint to cover ~4 square feet. Guess who is out of white paint because he didn't consider that 4 square feet?

Brightwork is prepped for clear coat. Rubrails will get a little careful wet sanding, then after the Bainbridge White is done on the interior, the brightwork and rubrails get clear coat.

I only masked one time and used an X-acto knife to cut the tape/paint interface, similar to the way ks8 did his.

Thanks guys. I am still getting accustomed to the way the S3 paint makes me ask myself 'What the heck am I doing here?" for a bunch of coats before I get to the "Dang, now that's what I'm talking about!" coat. :D
ks, that little bit of paint in that gutter was the subject of much pondering. I had a hard time deciding just how to end it on the inside edge. I ended up cutting a strip of white paper with various angles and concave curves to lay in there and get an idea. The K.I.S.S. version prevailed, so it's parallel to the centerline.

Here's some pics of the transom and knees.

I'm a little iffy on my treatment of the top edge. It is what it is, but now I wonder if I should have capped it with some of the dark mahogany.

Well, Ive done some painting on the inside and I think I'll need to repaint some of the lines at the edges. I'm trying for a shadow box effect here and I used the angle at the rubrail for the break. I didn't mark it in any way, just ran the tape where I thought it should go. My lines didn't come out very pretty.
Image

For the next section, I marked the line with a pencil before taping. We'll see if that gives me a better line.

Yes, Shawn, lots of masking and lots of tape. I just started on the second roll of 3M delicate surface tape for this boat. I like the standard blue tape, too, but I don't use it for edges. This is really a simplified paint scheme compared to the original one that I conjured up. Glad I changed my mind about that one.

I worked on the rest of the inside paint this weekend.
First, lets back up a few frames:
Image
See those big splotches of white just in front of the knees? I thought I sanded them down enough before I proceeded with the gray paint, but they not only showed through after two coats, they generated runs.
You can see it showing up on the starboard side in this picture after two coats.
Image
I sanded it down again until it looked a whole lot like the top picture, except a slightly different shade of gray. A few more coats and it all disappeared.
Image
After the gray dried, I masked for the white seat tops and gave them two more crosslinked coats. By some stroke of luck, I got a really nice line around the edges of the seats. Also touched up the frame ears where the paint somehow jumped across the masking tape.
Image
In between applying gray and white paint, I got after the cockpit seats. They had a few coats of epoxy on them that had to be sanded fair. Sanding those slots is a pain, but they sure do look good after 3 coats of S3 clear. :D

Yep, that's mahogany. I got it on ebay. :roll:
It came from a dealer that seemed to specialize in luthier stock. There are a few little worm holes, so I think it was rejected for guitars, but perfect for boat seats.

Steve, keep posting away. Remember a few coats of paint, especially neutral colors, can hide a bunch of stuff. When I started, I had a picture in my mind, but after going to Crystal River, it changed somewhat. The old picture tube must be getting weak, because it looks better than I imagined. Also, credit must be given to the designer. His "No ugly boats" philosophy is definitely working here. :D

I took care of a couple of details before moving on to clear coating the brightwork. The holes in the mast partner and step needed some more graphite/epoxy. The plans call for a 3° rake to the mast, so I also raked the step to the same angle. I wanted a graphite bearing surface in the bottom of the step, so first, I raised the stern to level the step, then stuck my poly tubing back in the drain hole to seal it off.
Image
Then I mixed a small batch of resin with graphite and poured about an eighth inch in the bottom. Also coated the hole in the partner.
Image
When this cures, I'll pull the tubing out and it's a step in the right direction. :D

Posted: Wed Oct 22, 2008 1:33 pm

Nice Gary, cool idea on the graphite. 8) Coat the bottom of the mast also, super slick. :lol: Nothing wrong with wormy mahagony, it adds character. I have several hundred board feet of 100 year old wormy walnut, some of which will go into the C17 which I got the Epoxy kit and fiberglass last week.

Now if I can just finish the dang Mirror. I'm starting to get frustrated. It was supposed to be painted and flipped last week until other things took precedence.

I know what you mean abut other things getting in the way of boatbuilding. We've recently had a substantial increase in our business at work and with that, smaller problems are magnified to an extent that they require more attention. That's why I spent last night re-hashing an old problem instead of mixing resin. The boss has gone off to a music festival for the rest of the week, so maybe a little more progress can be made. On the boat, of course. :lol:

Larry, I'm not sure about teak. I put some regular varnish on the O'Day's companionway slat guides and it's looking OK after 2 years. They were about dried out as they could be, though. I have a few scraps of teak that is a little more fresh, so maybe it's time for a test.

After fussing with the transom for a few days, I think I got it looking good. Here it is with the partially finished DB leaning on it for something to reflect on.
Image
I created problems for myself in the sequence that I used on the transom. When the boat was inverted getting the coats on the bottom, I only put two coats on the full transom because I realized I would be dealing with the top edge and gudgeon holes later. Most of those first two coats got sanded away and the top edge required a couple of coats of its own with a touch-up brush before the rest of the transom was wet sanded and finish coated.
Also got five coats of S3 clear on the foredeck and mast partner today. I need to work on lighting for that job because every coat had small flaws from missed areas. :?

The location is perfect for the smallest to the largest craft. An 8' pram or a canoe would be a blast at Crystal River. Snorkle with the manatee in the springs, anything that floats is safe there. Fantastic spot. It will be fun to have some blow boats this year.

More clear coating today. Knees and oarlock mounts are pretty much done. There's a sag back there on one of the little filler pieces that needs sanding down. Foredeck and dark trim is done. The partner would be, but it also developed a sag. I'll probably raise the stern again before I give it another shot. I have been using just a foam brush to apply the clear coat. So far, the best looking section I've done is the second coat on the underside of the cockpit seats. :?

Gary after you answer the coating question, I have to ask what you used to wipe down the mahogany down with prior to coating it. That is definatley not a good thing to have happen, sorry it happened to such a good guy. Keep the chin up. :D

Tom

Posted: Mon Oct 27, 2008 2:34 pm
by gk108
I think it's residue from the masking tape that I put on there when I did the white paint. That's about all I can think of. It's only the area that was masked off. At the same time I did the clear over the mahogany, I hit the top edge of the transom and it has an excellent bond. The other knee is fine and the holes in this one are OK, so I guess I missed this one. I know that I remember seeing residue lines before I went to work on these. Guess I didn't double-check myself. :oops:
Ususally, I just hit it with scotchbrite pad, microfiber tack cloth, isopropyl, then paint. I may try using mineral spirits before the isopropyl.

Posted: Mon Oct 27, 2008 2:45 pm
by Cracker Larry
Hmmm...all I've used for S3 prep is a scotchbrite pad, then water. No alcohol, no MS, no tack cloth. :doh:

A problem I've had is all my friends who come over like to touch, and most of them are mechanics and welders and longshoremen who always have greasy hands. I hate to tell them not to rub on it, so I have to degrease when they leave. I use Simple Green for degreasing.

Posted: Mon Oct 27, 2008 4:00 pm
by TomW
Gary, I have always used mineral spirits prior to any finishing, both latex and non-latex finishes and have never had a problem. I use a two rag system one wet and one dry. This is the trick, you want to leave it moist from the first rag, to have the second cloth wipe it dry. It has worked great for the System 3 primer and I'll use it for the WR-LPU also. I use some finishes in my woodworking as expensive as the System 3's so would not want to ruin it or them by using something that doesn't work. Alcohol evaoprates to fast for me, and water and bare wood don't mix.

This is something that goes back to my dad teaching me 40 years ago and something I'm sure he learned from cabinet makers before that.

Also see Dougsters post last Wed or Thur. when he asked the same question. Shine responded to that one.

I did what I had to at work and left early to give it another try. The rest of the clear is still holding fast and looking functional. I read the post about mineral spirits and that's what made me want to try that. It's always been SOP for me to wipe down with it for other paints. I used two rags for both mineral spirits and alcohol. Also added a bottle of Bass ale to the prep process. Things often go smoother that way. 8)

I didn't take any chances with the cool weather last night. I left a fan blowing on low and two 100W light bulbs in the boat. No condensation or any other funny stuff this morning. Maybe I can grab some time during the warm part of the day to get a couple more coats on the bad knee.

The Taco rubrail kit is going on after the finish is done, but I realized that I need to get the boat on the trailer to install the rubber. Stretching that rubber would pull the little thing right off the stand, so it needs to be held by the bow eye.

8)

Posted: Tue Oct 28, 2008 12:49 pm
by ks8
Thanks Gary.

I use an acetone wipe on bright finish epoxy sealed wood first... then after it dries, a 70% iso wipe mixed with 50% filtered water. Let dry. Then a 91% iso wipe. But if there is adjacent LPU in the area, you need to be careful with the straight 91% iso as it can soften cured LPU. I haven't had an adhesion problem yet, and I sand prep for LPU with 150 or, sometimes even 220. 320 concerns me about how much tooth it provides. I don't know the equivalent of grit for the various scotch brites.

The V10 is looking fine. 8)

Posted: Tue Oct 28, 2008 6:28 pm
by gk108
I've been sanding epoxy to 220 grit and any paint to 320 grit. It usually takes 2 coats of paint to cover the scratches from 320 grit. The Scotchbrite pads I have are green and brown. The green is more coarse than the brown. Their packaging indicates that the brown is for between coats, but I think that may be for softer paints than the S3 LPU. Comparatively speaking, it cuts about the same as #0000 steel wool on 1 part polyurethane varnish. I've been comfortable with what the green pads give me between coats. They do a good job of removing the sheen and 1 coat covers the scratches pretty well.

No progress today, too cold. :lol:

Posted: Tue Oct 28, 2008 7:27 pm
by ks8
So, why then did the clear LPU delaminate/peel? I wonder if it was a combination of the scotchbrite being not quite enough tooth and remnants of Simple Green? In general, water base coating will not have the same bite and grip as solvent based, hence even more care in degreasing and scratching the substrate enough. Let us now how the redo holds up, and what if anything you did differently. :)

Posted: Tue Oct 28, 2008 9:03 pm
by gk108
I have spent some time looking at the skin that peeled off and I believe I see enough evidence to suggest that it was masking tape residue from the white paint step. They were completely wrapped like this oarlock socket during that stage.
Image
The tape stretched across the holes in the knee and left no residue, hence the clear adhered well inside them. It also adhered to the spacer between the knee and the doubler along with a small area on the adjacent edge of the knee. Most likely, I got distracted and forgot to clean that one knee. The boat wouldn't allow that, though. I'm somewhat amazed at the immediate and dramatic rejection. She already seems to be developing a personality. :D

OK, I polished up the screw heads and installed the cockpit seats with a little dab of 4200 over each of the screw holes under the seats.
Image
Image
All the slotted screws finish with their slots running athwartships.

Then I drilled screw holes in the rudder and fastened the gudgeons and pintles loosely. After that, I put a little 4200 on the back side of each gudgeon, hung the rudder and pulled all the screws down snug to position everything where the rudder swings freely. Then I removed the rudder and pulled one gudgeon screw at a time, applied 4200 and replaced it.
Image
Image

Also installed the rear mooring cleats.
Image
The red handled wire strippers also have a screw cutter built in to them. I cut the excess length from the screws on the cleats and upper gudgeons and filed the burr off.

Getting closer. With the gudgeons mounted, she could float right now. :)

Great job Gary! I was debating about cleats where you've got 'em... minimal chafe... easy accessibility... but I put them under the knees instead and run the dock line up through the hole in the transom knees. I wanted to be able to lean or sit on the knee, and climb over the transom from the ladder, but now I have the chafe issue to watch through the hole.

Your cleats are a nice detail there and very accessible. Shiney! Great finish on the knees too (glad to see the LPU stuck this time :) ). Real nice all around. How and where are you going to fly the flag? :D

Thanks everyone. I wasn't trying to raise the bar. Really, I'd rate it at about a 7½' finish. You guys that fish spinner baits understand how distracting a few bits of shiny metal can be. :D I just want it to age in a uniform manner. Polished cleats, rough cast oarlock sockets and mill finish screws just didn't match, but now it all does.

I pondered hard and long about the rear cleats. I finally decided that accessibility trumps everything else. I want to be able to lasso those things if I need to.

I still have the Taco rubrail to put on it and some other minor things, but she should be floating within a fortnight.

I tried to cross the grain with the dowels on my tiller. They are some kind of dark oak dowels and the end grain is funny looking, so it's hard to be sure about them.

Both mast and boom are still in raw form and need to be cut to length, finished and fittings attached. Crutches need to be designed and fabricated. Appendages need clear coating and other details. Lots of work.

I'd like to see Measure Of Faith in CR, too. I'm not sure how I'd do in the regatta. Those two boats could probably gang up and blanket my wind from the other side of the course. 8O

Larry, you can sail her any time. After I get a little time in her, I'm going to try and get jbo to find the right place on Chehaw to put her in, then see if we can get him thinking about camp cruising in an AD14 with a tabernacle. And I guess flatpicker and I will just take her down to Miccosukee some time. :D

I'm all for a trip on Chehaw(still Lake Worth to me), but it may be boring. There isn't really enough lake there. If you haven't ever been, it's really only river channel and stump-filled flats, no real lake. But maybe you know something I don't.

Blackshear should be good, but they just drained it, so you've got a month or two to finish.

Otherwise, you tell me where and when and I'll try to get there for a ride. I'd love it.

The Taco rubrail is finally on, mostly.
It wasn't too much trouble, I just had to make a plan and it all fell into place. Here's what it looked like after I soaked it in hot water and stretched it out along the port side.
Image

The bow was contoured and rounded a little to allow the rubber to bend easily. I bought the Taco kit months ago while the boat was unpainted, so I could get an idea of what I had to work with.
Image

The transom corners are not all that rounded, but the heat gun and a couple of screws did the trick.
Image

I opted for the black insert because all of the white ones I've ever seen get really nasty looking as they age. I still haven't put the insert in because the end caps use a smaller screw than what is supplied. It's not real pretty, the screw heads boogered up the rubber almost every time. This is the smallest size rubrail and the screw heads are a good bit bigger than the outer edge of the slot. I tried soapy water and all that, but it still left marks. The black insert should help hide some of it.

Looks great GK :!: I wish I could have got my bow as nice as yours, but we know how for next time. That's first class 8)

My rubrail was the largest size, but I had the same trouble as you with the screw heads. The screws provided had a head much larger than the slot. I put 3 of them in my pattern pieces and buggered up the rail with each of them. I could see this wouldn't work out, so I went to the hardware store and bought 200 #12 panheads that would just clear the slot. Much better results :wink:

Those end caps they supplied really suck, don't they?

You must have read my mind. Right now, I'm wondering if I should spend the winter whittling some caps out of mahogany. I'm really happy about the fact that I didn't drill all the way through the laminated wood for any of the screws. There were a couple of areas where I had to get 1" long screws to accomplish that. Even though their heads were smaller, they still left their mark on the rubber. I guess I'll have to run into some docks and stuff to make all the bad spots look natural. :oops:

That was the other problem with the factory supplied screws, they were 2 1/2" long and my rail is only 1 1/4" thick :doh: And I sure didn't want 200 screw points sticking through :?

I've also thought of either whittling or maybe casting some decent end caps. I was thinking maybe a mold and cast them with graphite/epoxy mix.

It's been over a month. Plenty of time to cure. Right now, it's just tiny little blisters that feel more like a light sprinkling of non-skid grit. It's still firmly stuck to the boat, no peeling, and I tried. The most troublesome thing is that the exposure to water didn't amount to any more time than a weekend at the beach would have given.

When I sanded for the Kiwi Grip, I saw just how much paint buildup I had. It's plenty thick enough. I'm wondering if this is because I thinned the last coat too much or something. I guess the best remedy for now is to get a tarp that doesn't leak. :oops:

You've got me concerned about the S3 paint also. Mine hasn't been wet except for a few hosings. It has had water standing overnight a couple of times. No problems yet but she's got to move outside this week. You'd sure think marine paint would be waterproof :doh:

So far it has held up well in the garage... :lol:

With reports from others of two weeks in the water with no problems, this sounds odd. Sounds like S3 definitely needs some way of keeping the cockpit overall dry.

You thinned with only water, right? Was it distilled or filtered water? Or from the tap? What was used for surface prep wipedown? Just covering the basic questions. I don't like cleaning up with soap and water unless I get OCD about rinsing every bit of soap out of containers and brushes. :?

Larry, I got the copper powder today. That stuff should look good! I owe you one, or maybe two. :D
Still working on a pattern. Someone suggested a few other possibilities like sand dollar, scallop shell or starfish. It may take a trip to the coast to find something suitable.

ks, I used filtered well water to thin. A little high in dissolved calcium carbonate, but otherwise quite pure. On these areas, I cleaned with a water/alcohol mix most of the time. No soap because I don't think I could adequately rinse it away. No mineral spirits, but maybe I should have??? I always sanded and cleaned right before painting to minimize any exposure.

I don't know what to think now. Some of the places have dried out and smoothed back out like nothing happened. I already know of a few "good for me" boat paints, so I thought I'd try this on a little boat and see what it is all about. The data is still incomplete. I can tolerate what I have. The data will be complete when it gets to the point that I decide it's time to repaint.

I may look into installing an autobailer just for a drain while sitting. I'm not sure if a V10 goes fast enough for an autobailer to actually auto bail.

Any progress report on that casting GK :?:

Posted: Fri Dec 12, 2008 6:43 pm

I'm just about tooled up for it. The instructions for the silicone product just barely mentions bubbles and suggests restraint while mixing and brushing on a coat before pouring the rest over the pattern to prevent them. From past experience, I know that this won't work. Mixing the two parts will require something on the end of a drill. A viscous product like uncured liquid silicone rubber will trap a LOT of air that way.

In the factory, we used a lab grade vacuum pump and bell jar to pull a vacuum on the liquid after it is poured directly on the pattern. Divers know about Boyle's Law: For a fixed amount of an ideal gas kept at a fixed temperature, P [pressure] and V [volume] are inversely proportional (while one increases, the other decreases). Drawing a substantial vacuum on the uncured liquid silicone will cause even the smallest bubbles to expand the the point that Archimedes Principle forces them to the top, away from the actual mold cavity.

Instead of the heavy duty vacuum apparatus, I ordered a small hand operated vacuum pump from Harbor Freight and it just got here. Now, I have to fabricate a suitable vacuum chamber, probably a modified Rubbermaid product.

At the factory, we normally poured the epoxy casting compound and just let it cure. For some of the abnormal projects that I used it on, I would also subject the filled mold to a vacuum. That always seemed to make a denser part with excellent details.

I've consulted my dad, who is the expert on pattern making for this process, and he advised that anything from the original part that could be incorporated into the new pattern would really cut down on the pattern making time.

Time is a big factor for me right now. I need an extra day in the week, especially this week. Somebody went and published TWO new boat designs that I had to study. :help:

Pattern making should commence next week. :D

Posted: Sat Dec 13, 2008 12:44 am
by ks8
I've also seen where the mixed rubber is put under the vaccum first, before the pour, to bring all the bubbles out before the pour. But I'm by no means the mold master. Take pictures during the project, of course. :)

That is... when you can pull yourself away from the study plans...

This may help... look at the sheet count on the GS. Surely worth it, but wow, it adds up fast as the boats get longer!

Posted: Sat Dec 13, 2008 10:28 am

The GS28 looks to me like it would be the one to build if you wanted a six pack charter fishing boat on the Gulf. One captain that I know spent the summer operating at mostly break-even level just to keep the business going during the $4/gallon gas prices. I can see where the GS would give him a break because of its lighter weight and lower HP requirements. It's not the boat for me, though.

The MM21 looks interesting and it's definitely closer to what I'd want. The way Ross built his HMD18 really helped keep it at the top of my list, too. I'll give myself a year or so to make the decision. :D

I took her down to the Ochlocknee Bay and enjoyed a perfect day for splashing a little boat.
She'll pinch up to about 35° off the wind, run downwind like she's on rails and top out at 4.8 mph on a broad reach. The tyvek sail performs much better than I thought it would. Balance isn't perfect, but not far from it. I crossed the bay 4 times while giving her a good test. Plenty of spray over the bow and green (brown) water over the side a couple of times. :oops: Best of all, she gave me an afternoon of 100% fun. What a fine boat the V10 is :!:

Thanks, ks and Craig. I'm still smiling about it, myself. :)
Craig, that's the place. You may remember the landing on the West side of the bridge. It never really has been maintained, so it's more like a beach launch. The bridge has been replaced since the '70s. It's in the same place as the old one, only with a hump in the middle. I stayed inside of the bridge because I didn't want to find out what the wind was doing as it went through the pilings. 8O
Not much forward progress at 35° off the wind, but even at 2 mph, it's enough to allow me to maneuver. Sailing the O'Day has made me a little lazy and I don't get real concerned about sailing directly to a mark. Each trip across the bay, I was able to sail the V10 right back to the landing without any trouble.
The only major adjustment that I can see is lowering the attachment point for the snotter. No problem, since it is a temporary lashing right now. Once I find the right spot, I'll do something more permanent.

jbo, I sure didn't want to subject you to this unproven rig. :lol:

ks, check out page 1 of this thread. :oops: It's just a flat sheet of tyvek with some camber in the luff. The sail did stretch some body into itself as I used it. The tape around the edges is heavy enough that it has no stretch. The overall effect in a 10 mph breeze made the sail look like it had a very tight leech line with more fullness aft than what is best in 10 mph wind. Instead of spilling wind, it just tends to make the boat heel more. Lowering the sprit should make it have less tension on the leech and more on the foot, so maybe it will cup less and spill more. :doh:

Posted: Wed Dec 24, 2008 3:08 am
by ks8
Forgot about page 1. That was awhile ago. ... ok... not as long ago as my page 1. :lol:
Obviously, the hull isn't drawn right, but the basic dimensions are to scale.
:lol:

That would be great if the camber moves forward or if you can flatten it more for close hauled. And then see how long it can last in the sun and wind. Please let us know how it shapes when you reposition the sprit. Excellent that she sails well with it as is. :)

Total cost for the sail?

Right around $60 for materials for the whole thing. I'd say cost is comparable to a polytarp sail. 1 lb 3 oz is all that it weighs and most of that is around the edges. 8)

I made some crutches for the spars, since the mast is too long to fit in the boat.

This one is made from the extra length cut off of the mast.

This one is made from the extra length cut off of the daggerboard trunk. It has clear vinyl tubing over the dowels. Rolling the snotter around the sprit provides enough cushion between the sprit and mast to prevent chafing.

Just to make sure all aspects of finishing are done wiht unfamiliar products, I've switched to Minwax Helmsman spar varnish in a spray can. The transom crutch is varnished in the pictures and now the other one is, too. This practice helps develop a scheme for varnishing the spars. It looks like I'll hang the mast horizontally and spray the whole thing at once.
Yesterday, when I sealed the front crutch with epoxy, I mixed graphite with the leftover resin and coated the foot of the mast and the area where it contacts the partner.

A name like Mjöllnir sounds like it might attract or invite challenges at an entirely different level, especially if you are in the habit of whistling while you sail.

Yeah, the weather has been almost intolerable. :D Naturally, the best looking days are the ones that I have to spend at work. Yesterday was perfect, but I had to deal with a recording session that turned out to be more of a rehearsal than anything else. I can record over the tape, but there's no recycling of the lost time. Something to do while the varnish dried, anyway. :?

Some details on my temporary snotter rigging. This is a loop of rope made by short splicing the bitter ends together. It's long enough to wrap around the mast 3 times plus a little extra.

Here it is in place. It's wrapped around 3 times with a tuck under the top turn. The lower end of the loop with a block for the snotter is pulled through the upper end of the loop. Tension on the block pulls the loop tighter from both ends and the tuck holds it in place, yet allows adjustment.
Image

When I find the best place for the sprit boom to ride, I'll use a shorter loop or grommet and a thumb cleat or strap to hold it in place.

I finally have some pictures of the beginning of the rubrail end cap casting. Lately my boatbuilding time has been split between this project and making a custom cover for this boat. More on that later.
Here's the completed pattern:
Image
Image
I used one of the original caps to start from so that the contours would match. Some plastic was removed from the tip just to make things fall in place better. The plastic star was then attached and faired in with modeling clay. A slight draft angle was included and overhangs that might catch a line were eliminated.

Image
This simple shape will be cast in an open mold, so the pattern was stuck to a coffee can lid with a dab of modeling clay and a light mist of vegetable oil was applied as a mold release.

Image
A bottomless paper cup serves as the side of the mold flask. It's sealed to the coffee can lid with more modeling clay. The liquid rubber ratio is 10:1 by weight, so a good scale is necessary. For this mold, 100 grams of the white part and 10 grams of the blue part made just the right amount to cover the pattern in the flask.

Image
Mixing the two components for the rubber introduces a lot of air bubbles into the compound. Subjecting the liquid to a vacuum is the best way to de-gas the rubber. For a vacuum chamber, I found a locking food container with a good rubber lid seal at Wallyworld. Here, the rubber has been mixed and poured into the mold flask and the vacuum is being applied. The little hand pump achieved 22" of vacuum and it was held for 20 minutes. At that low pressure, the bubbles tripled in size and floated easily to the top (bottom of the finished mold), away from the pattern.

Image
Vacuum removed, waiting for overnight cure of the rubber.

Image
The finished mold, ready to cast epoxy.

Stay tuned for part two. :D

No pictures yet, but I cast one piece last night and the results are less than satisfactory. I wanted a small amount of silica in the resin, along with the copper. My ratio was way wrong. Way too much silica and not enough copper powder. The resin was too thick and I ended up with bubbles that didn't rise to the top. The next try will be with practically no silica in the mix and double the amount of copper powder. What I have now looks very promising, though. Just needs more debugging. :D

The copper powder kind of surprised me when I added it to the resin. In the can, it looks like it is rather coarse, but when it hits the resin, it becomes apparent that it is very fine particles. The little bit that I added worked more like adding pigment to the resin than adding filler.

BTW, the plastic container imploded during another attempt this morning. Another part is curing, though. 8O

Thanks guys. I never would have tried this if you hadn't suggested it, Larry. I made a few changes for the next one to accomodate a serious overkill vacuum chamber.
Image
I used the battery case from an old cave diving light. Tried and true and tested to 240 ft. depth. It won't implode from a little vacuum. 8) I had to make a haywire lifting bail for the mold, so I could get it in and out of the housing.

Image
In the can, under 22" of vacuum for 20 minutes.

The mold conveniently holds 9ml, so the material breakdown is 9ml of mixed resin and 1.5ml of copper powder per part. It wouldn't take much more copper powder to make the resin too thick to flow well enough. That's the drawback of using a general purpose laminating resin instead of a resin formulated specifically for casting parts like this. Of course, casting resin only comes in gallon kits and that's a lot of small parts. :)

Peter, several months ago I bought a Taco rubrail kit. The plastic end caps supplied in the kit were plain little black pieces of plastic. With a little encouragement, I decided to try doing something a bit more decorative.

Craig, that was 6ml resin, 3ml hardener and 1.5ml of copper. I filled the mold to the top, which left some dregs in the resin cup. After vacuuming it, the level in the mold is a bit lower because of the removal of air bubbles. I added enough of the remaining resin to fill the mold again and let it cure. There was a little bit left in the mixing cup, better than not having enough.

I'll let these cure good, then clean them up and drill the holes. I suppose a few coaats of clear LPU will help them stay nice looking. I also need to round up some suitable screws. :D

More little details are getting finished up. The hatches in the front frame use simple turnbuttons to hold them in place. Well, simple with a couple of twists.

Mahogany handles with 2 convex plastic hole plugs for bearing surfaces. Conical spring from a Delta faucet repair kit. The hex nut will be replaced with a self-locking nut.

My first idea was to just put a very short piece of rubber hose on the screw and call that a spring. I couldn't find anything soft enough, but I think the back of my mind was insisting on a conical spring, anyway. I had a :idea: moment right there in Lowe's.

Larry, the cover has been quite a challenge for me. Much more complicated than the sail, even though I'm trying to make it as simple as possible. With your T-top, a full cover would be quite a project. A worthwhile project, though. I was quoted $500 for a custom cover like I wanted. 8O

I know it will look a little different, anyway. It has some rhomboid shaped cabin windows that won't stop leaking, no matter how much sealant I put on them. They will most likely be replaced with a couple of 5" round ports on each side. Other, more serious problems than that, though. At least I have something to sail around in during the rebuild. :D

A little more progress to report. I've managed to find a couple of opportunities to sail with the tyvek sail. While it performed quite well, I just didn't like the excessive cup in the leech. In light winds, it is fine on all points, but as soon as you get enough breeze to really heel the boat, the sail wouldn't spill wind. Instead, it seemed to move the CE out towards the leech.

I ordered a kit for a custom variant of a Bolger Nymph sail from Sailrite and put it together Saturday. It's dimensions are the same as the sailplan on the first page of this thread, except that it's vertical cut and has a hollowed leech and some round to the foot.

I only have a few pictures of the assembly.
My work area for this and the cover, which is 90% finished.
Image

Setting up to sew the inside edges of the clew patches. Spray glue hold them in place for stitching. The foot and leech have a double folded hem that covers the outside edges.
Image

This shows one of the middle panels before sewing. The shiny stuff on the seam allowance is backing for 2 sided tape used to hold the panels before stitching them. The curved seam gives body to that portion of the sail. The rest of the sail is rolled up on pool noodles. I tried other things but the flexibility of the noodles worked better for me than a cardboard tube.
Image

I tried it out at a local lake for a couple of hours on a puffy afternoon. No pictures, but I like it. :)

After my last little venture to check out the new sail, I was inspired to rig a jack line to douse the sail. It's the blue line in this 441 X 600 image:
http://www.gk108.ersweb.com/images/V10/V10sailplanb.jpg
It's made fast to the mast about 22" above the partner, runs aft to a fairlead 18" from the aft end of the boom, runs forward along the boom to a fairlead 12" from the front of the boom, up the mast and through a fairlead back down to a clamcleat. Easing the snotter and heaving the jack line pulls the forward end of the boom upward while pulling the aft end up to the mast, dousing the sail. Most of the way, the aft end of the boom is supported by the leech of the sail, but as you pull the last couple of inches, the weight of the boom is taken off the sail and supported by the jack line. Once it's all pulled up, a sail tie or two holds it all in place.

After a bad first try, I'm making some good progress on a carbon fiber boom. The first attempt was a failure due to the carbon fiber not being fully wet out. That was solved on the second try by wetting each layer of the laminate before the next one went on. Sliding dry sleeve over wet sleeve wasn't as difficult as I thought it would be. I used a foam pipe insulation core and heat-shrink tubing. The heat-shrink tubing was a lot more difficult to slide over the wet layup. After that, it's been a breeze.

Image
Forward end of boom showing mounting saddle for a fairlead and composite end cap. There is a 5" long aspen wood plug in the end, hollowed out for 2.5" on the inside. Directly behind the saddle a hole will be drilled to attach the snotter. Also, there's an extra layer of glass added for a couple of feet where the boom will be in contact withthe mast.

Image
Aft end of boom showing sheet attachment point and end cap. Same type of wood plug on this end. I prefabbed some skeleton material out of glass and epoxy that is 1/16" thick. I laminated a strip 1" CF uni tape lengthwise between two strips and stuck that to the tube with a dab of 5 minute epoxy. Next came a fillet on each side to make a teardrop shape. On top of that, I wrapped it with CF uni tape and a layer of 9 oz fiberglass tape.

Right now, it looks like it will be about half the 4 lb 7 oz solid wood boom weight. 8)

One thing for sure, mistakes with CF are expensive! Right now, my weight savings is costing me $80 a pound if I count the materials used in the failed attempt. I expect that figure to change radically when I replace the 13 pound solid wood mast.

Some specs on the CF tube based on the offcut from the ends:
Wall thickness - .045"
Weight - .2 oz (5.3 g) per inch

Gimme some time and I'll calculate modulus of flexibility if I can. :wink:

Gary,

Good job with the CF spars. I think you'll like them a lot. I used them on my V12 and have been very happy. It's really nice not having to worry about rot, glue joints, knots, grain, etc.

The mast was made from the kit Jacques sells and turned out very well. It weighed about 2 lbs before painting. The sprit is one I tried on my own that ended up useable. but not as nice as the mast. The 2 big problems I had were trying to use a metal mandrel and trying to wet out all the layers at once while consolidating them with heatshrink. A foot-long test piece worked beautifully, but scaling up to 9 feet didn't work as well as I'd hoped. It's plenty strong, but between one thing and another, the sprit ended up slightly heavier than the mast.

Next time it's back to the foam mandrel and wetting out 1 layer at a time. I'll give the heatshrink one more chance, but it didn't really seem to make that much difference over doing it by hand.

To finish up, I plugged the knee of the sprit with a wood plug, just as you did on yours, and drilled a hole for the snotter. The nose is a shaped dowel. The top of the mast is plugged with glass, epoxy & woodflour putty. There's a SS eyebolt up there to lash the throat to. Speaking of lashings, everything is lashed together. The block for the snotter is held to the mast with a prusik knot and the downhaul, snotter (and eventually the brailing line) go down to a wooden collar (glued to the mast) which has 1/2" pins like fixed belaying pins for the lines. The collar & pins worked out really well -light, strong, cheap and allows the mast to rotate unimpeded.

Here's a couple of shots from last month when the boat made its debut as a sailboat at the Mid-Atlantic Small Craft Festival in St. Michaels MD.

Have fun with yours,

Laszlo

Thanks, Laszlo. Yours looks great. I've been using a similar lashing for my snotter block on the wooden mast. I never seem to be able to locate it in a consistent position, even though I drew a line on the mast. I may just mold a couple of little bumps on the side of the CF mast to help me with that. I like the collar and belaying pins. I may try something like that, but my mast will need to be taller. Right now, I'm using clamcleats for snotter, downhaul and furling line. I had planned on making the new mast at least 6 inches taller to give me more room around there. If I add 10 or 12 inches, that would give me room for belaying pins.

I may very well try the mast without using heat-shrink tubing. I just need to devise a method to keep it all straight while the resin cures. For the boom, I used a copper pipe through the insulation and it fit loosely. It was stiff enough to make handling easy. After heat-shrink, I laid the assembly in a cradle made of two pipes pushed together side by side. That made it nice and straight with no flat side from laying on the floor. If I do the mast without heat-shrink, I'm thinking of using the same loose mandrel with a rope or wire running through the center. After the wetout, I can stretch that between two trees or something to hold it straight while it cures. I'll have to do a dry run and see if that (or something else) might work. 8)

Wes,

Thanks. I put reinforcing glass under the CF at the top, bottom and where the mast fit against the partner, as well as where the snotter attaches. The result was a very slight narrowing of the mast at each spot. This makes it very easy to find the right spot to lash the snotter block.

When I did the sprit, I tried supporting it on a very tightly stretched horizontal line (3/4" nylon stretched tight enough with a come-along to twang like a guitar string). It still sagged. What really worked well was hanging it vertically from the garage ceiling (10 feet high) with a weight at the bottom. In your case you might have to build a frame outdoors.

You might be able to do the stretched line if you let each layer cure hard before you put on the next one. As it gets heavier, it'll also be getting stiffer. If you're lucky, it'll be getting stiffer faster than it'll getting heavier. All depends on your lamination schedule. But from a theoretical standpoint, only vertical will get it perfectly straight. Horizontal will always be a caternary, but if you're lucky it'll be close enough to straight that no one will notice.

Have fun,

Laszlo

I finally constructed an oven to post-cure my spars. I used 2 sheets of foil backed foam insulating board and made a 1 ft. X 1 ft. X 16 ft box.
Image

Powered by a heat gun set on low and blowing into a short pipe. There's an exhaust vent at the bottom of the opposite end.
Image

Temperature somewhat regulated by a water heater thermostat fastened to an aluminum heat sink. Boom has been coated with white pigmented Silver Tip.
Image

Baked 4 hours at 140°F average and it's ready for sea trials. Spars lay in V cuts while baking.
Image

This seemed to work well and the boom seems to be slightly stiffer. I guess I'll be ready to move on to the CF mast soon. :D

I used a cheap digital meat thermometer to monitor temps. That allowed me to check different areas by just poking a hole about anywhere on the box.
Image
The pipe was really the key to uniform temps. Initially, I was worried about the heat being concentrated wherever the heat gun blew in, but there seemed to be plenty of radiant heat from the pipe near the heat gun end of it. During operation, temps were always within 5° no matter where I put the thermometer. That really surprised me. Eventually, I just left the thermometer in the middle joint of the top.

Now that I'm ready to try it out, there's not a breath of wind around here today. :?

With the success of the boom, it's time to start getting prepared for making the CF mast. I need some extra thickness built up in the area of the partner and a little bit above for hardware mounting. Rather than compress the 2" O.D. foam that will be the core of the rest of the mast, I thought I'd try wrapping the next size smaller foam with the layup and then using stretch wrap. Ultimately, I should end up with a wall thickness of about 3/16" once this part is done.
Image

After the stretch wrap is on, I punched a whole lot of holes in it to allow excess resin to run out. It was a warm day and by the time I got to the stretch wrap, resin was starting to get warm. I'm going to take that as a sign that it is about thick enough.
Image

I'll probably need a little more diameter on this part and once all of the adjustments are made, it will be stacked on the mandrel between pieces of 2" O.D. foam. I had been wondering about using stretch wrap for stuff like this and Duckworks posted a helpful video link the other day. I don't know if it is going to be the best way for the whole mast, though. I really liked the results using heat-shrink tubing on the boom, but getting that stuff on the mandrel was tough. That was only 8 ft. and I'm worried that twice that length might be more than twice as difficult to handle. Since I let the stretch wrap run past the bulk of the layup, I'll get an idea of what it will look like with that over thinner layup like the majority of the mast will have. I hope. :doh:

Waiting for the August heat to subside. That botched first attempt on the boom has me a little gun shy, so I'm waiting on cooler weather to maximize working time. In the meantime I'm cutting odd shaped pieces of plywood and tacking them in place on my rebuild project. I should get to a place where I will be slinging epoxy at both projects soon. At least that's the plan.

Wes,

Your oven beats the heck out of my post-cure arrangement of black plastic garbage bags out in the sun. Very nice.

I used shrink wrap on my CF mast and what it ended up looking like was a whole lot of sanding. It's good stuff, but leaves lots of wrinkles. It's also flimsy enough that if it gets stuck in an epoxy glob it tears. Bet you had fun getting that layer with all the holes and drips off :-)

Topwater, the very first try on the boom was a flop because I didn't have time to vigorously work the resin into the CF. Even after wrapping it, the resin didn't saturate the layup very well at all. The result was a tube that was about as stiff as a pool noodle wrapped with duct tape. On the second try, I had cooler temps and more working time, so I was able to wet an inner layer of glass, then slide the CF over that and wet it and work the resin into both layers by hand before sliding the heat shrink tubing over it. Getting the heat shrink on was the cumbersome part of that. I don't think I will be able to easily work with heat shrink to wrap the mast, due to length, so I gave the stretch wrap a try.

The wrinkles weren't too bad on the little section that I made and the pinholes in the wrap didn't even show. I didn't know what to expect when I took the wrap off of it, but it was about the same as cutting that much shrink wrap without any resin involved. There were a couple of wrinkles that had wrap stuck in them, but either a small wire brush or a dental pick got them loose enough to pull off.

One day last month, it was perfect for sailing on Lake Seminole, so I dropped everything and went sailing. Steady 15 mph winds and a 2' chop made for a good test of the new boom. Downwind was a hoot, new speed record of 6.2 mph. Upwind was a soaker, but the spray was welcome on such a hot day. The only thing I'll change on the boom is the way I fasten the clew, rope instead of a SS hook. 8)

I'm finally getting started on the mandrel for the mast.
I'm using a combination of ½" conduit and ¾" PVC pipe for the core. That should be enough to make the assembly easy to handle.
Image
The built up section is about 3/16" thick, as shown by the offcut. It will float on the conduit and hopefully will be centered by the CF and fiberglass sleeves.

Image
A few turns of electrical tape helps center the PVC on the conduit. Not a snug fit, about 1 wrap of tape less than snug.

Image
Mandrel assembled. There's about 3" of PVC extending beyond the far end of the foam. Near end of the foam and PVC taped to help the sleeves slide on easier.

Image
Foam spliced with packaging tape.

The PVC is in two pieces. After the layup cures, I'll be able to pull the short PVC piece and the conduit out from the bottom and the other PVC piece will pull out from the top. At least that's the plan for now.

Looking good, lots of work though. I'm curious as to the weight savings between this and an aluminum mast? The cool factor of building your own carbon mast is definately there, but what other benefits are there?

Very cool GK, i like the the cup idea to pull on the sleeve. That section you put at the lower end is that
where the mast will meet the deck?

Materials and all cost a little less than an aluminum mast, weight will be about half of the current wooden mast. Some hardware fittings can be replaced with composite parts, so there's a few ounces less weight there, too. Less weight aloft means less heeling force made by the weight of the mast. In a small boat, every little thing makes a big difference. Even though the prep time is longer, the total time to make a CF mast is a lot less than what it took to make a wooden mast. When I started mixing resin, the whole process of assembly and lamination took about 2 hours. (Yep, it's done-pictures later this evening) Compare that to the week or so it took to make the blank wooden mast...and the 2 gallon bucket full of saw/sanding dust. 8O

The reinforcement sleeve goes from 4" below the mast partner to about 10" above it. There's a couple of cleats that mount there and that insert provides some extra meat for the screws. Jacques mentioned the importance of providing a break point in the mast so it will snap before storing up too much potential energy. The top of the insert should make enough of a hard spot to snap it there. I hope I don't have to find that out the hard way. 8)

First layer of fiberglass sleeve is wet out.

Image
First layer of carbon fiber sleeve pulled on the bottom 4 ft of the mandrel and secured with masking tape.

Image
Bottomless paper cup guide is removed from the first carbon fiber layer.

Image
Wetting out the first carbon fiber layer and working the resin into it by hand. You need to purposefully force the resin into carbon fiber because it doesn't seem to wick it up like good quality fiberglass will. That's why infusion is a common method used in carbon fiber production.

Image
Smoothing that layer out and getting it ready for the next.

Image
Pulling the second carbon fiber layer on the mandrel. This one goes full length.

Image
Wetting out the second carbon fiber layer.

Image
Still wetting out the second carbon fiber layer, working the resin in and smoothing it as I go.

Image
Second (outer) layer of fiberglass sleeve is pulled on. By this time, the whole assembly was about saturated with resin, which transferred to this sleeve while I was pulling it on. That made it the most difficult one to put on the mandrel, but still no big deal, just smooth it out and keep going.

Image
Wetting the last layer.

Image
Everything well wet out, dripping in some places, ready for spiral wrapping with stretch wrap.

Image
Wrapping with stretch wrap to the end...

Image
And back.

Image
After the stretch wrap is on, it gets perforated with the pounce wheel and most of that excess resin oozes out as waste. This picture is bigger so you can see the lines of resin droplets.

Image
Inspecting a minor cosmetic flaw.

Right now, with 24 hours of cure time on the slow S3 resin, I'm happy with what I see. The mast blank, with mandrel removed weighs 4 lbs. 3 oz. Compare that to the 12 lb wooden blank that weighs 14+ lbs. rigged. It will make a noticeable difference. I'll probably miss the inertia but not the weight, if that makes sense.

First list of things I'd do different:
1. Triple overlap the stretch wrap on the first pass. I have spiral lumps. Not too bad and certainly not any weakness from them. The heat shrink tubing method that I used on the boom left some lumps, too. They have no interesting form to them, though.

2. As a preliminary step, I should have used a fiberglass sleeve to glue the reinforcement insert to the foam on either side of it. I don't have a smooth transition from insert to foam, especially at the top. The good news is that I definitely have a place where the mast will snap before it stores up too much potetial energy.

3. Since everything in the mandrel is hollow tubing, it might be worth stringing the whole shebang on a taut wire rope for some of the final steps including cure.

I've experimented with dry runs of peel ply under stretch wrap. With a soft foam mandrel you slightly compress the foam as you stretch the wrap and that reduction in circumference creates wrinkles in the liner fabric that looked to me like they would cause more problems than they would solve. The stretch wrap makes wrinkles, too, but they are shallow and easily filled. The peel ply wrinkles looked like they would starve the layup of resin by either trapping air or spot pinching it dry. 8)

Part of the reason for experimenting with the peel ply was to just get an idea about how an arrangement like that would go together because at one time I was considering a layer of fake woodgrain Chromaveil fabric under the outer fiberglass layer. When that didn't work, I was discussing it with the boss at lunch one day and his comment, "Let me get this straight, you want it to look like wood, so you're going to glue a picture of wood to it?" kinda made me decide to paint it instead. :? :lol:

The pre-fabbed fiberglass spine is 1/16" thick, so with what is on the drawing, it should end up about 1/8". I'll probably glue a couple of bits of the spine material on the outsides to get the protruding tab up to around ¼" thick total when finished. Then I'll overdrill the hole and fill it with silica/epoxy and re-drill for whatever shackle I use. 8)

I plugged the ends of the tube. Here's the hollowed out wood plug for the foot. The hollow end goes inside.
Image

While that was soaking up some resin, I prepared the tube with a stop to hold the plug in place and a tape cofferdam to make a composite cap to protect the end of the tube.
Image

Then I buttered up the hole and the plug with thickened epoxy and pushed it in to the stop and poured the remaining thickened epoxy up to the top of the cofferdam.

Current weight of the mast is 5 lbs. 0.9 oz. with a CG at 60" from the foot. I'll probably add another pound of fittings, either molded in or screwed on and I don't expect CG to move too much from them. That's a pretty big difference from the 14 lbs. / 72" CG of the wooden mast. 8)

I thought I'd learn a little more marlinspike seamanship while waiting for some parts for the mast.
I bought some 12 strand single braid from Duckworks a while back. Closeout stuff that they don't carry any more, so the lines that were cut for the wooden mast are a bit too short for the new mast and I can't buy more rope.

First try was a mobius brummel eyesplice. I didn't need an eye spliced in anything, but it was what the Riggers Apprentice showed. It's mostly designed for a splice where the standing part is really long or not accessible at all.
Image

Next was a simpler brummel splice to add length. Using a marlinspike, open a hole through the braid 24X the diameter away from the bitter end of each half. Pull the standing part of each half through the hole of the other half.
Image

Closeup of that step.
Image

The standing parts are pulled up to where the eyes meet, each tail is tapered and tucked inside the standing part of the other half, leaving out one long strand.
Image

To prevent the splice from working loose while not under strain, the tails are stitched in place with the remaining strand.
Image

That's good enough to pass through fairleads and grip in a cam cleat and strong enough that I can't pull it apart. Should work fine for a furling line. 8)

I just like that particular rope for the application. Single braid polyester, limp yet strong. Business has held in there, down slightly for the year, but still shipping a thousand or so orders each week.

My personal electronics are a different matter. I have a half dozen worn out PA drivers to replace and I'm re-coning them myself, something I've never tried before. Expensive learning curve, $70. wasted already.

Thought I'd use my old Crown DC300 amp to test the re-cones, but the bridge rectifier in it decided to short after 35 years. I'll fix it and retire it, to be replaced with a new Crown amp with switching power supply. If I have a busy enough schedule in the next year, all 3 front-of-house amps will be replaced with new Crowns. That will make the amp rack weigh 120 lbs. less, since the big transformer in each amp is eliminated by the switching power supply.

Bad channels in my 100 ft. audio snake, too. The stage box got soaked in a rain shower a couple of years ago and the effects are really showing now. That should be cheap to fix, panel connectors on order.

Lotsa work to do, but it sure makes for big fun when it is all working right.

A suggestion... before you close up the stage box, after soldering on the new XLRs, give 'em a good wigglin' on the lead wires from the snake up to the xlr or 1/4 inch conns, with a mic plugged in each xlr, one at a time, maybe even a phantom power condenser, to make sure no water found its way in to the insulation to cause trouble. Keep the main amp low and crank the pre-amps, sliders, whatever you've got, just short of distortion. Listen on the phones. Depending on your output, and how much the talent likes to stomp around, some vibration and *damp conductor* might cause some background crackling under vibration, you know, one of those annoying *now what?*'s. :help: On the 1/4 inch lines, that's not quite as fair a test, depending on how well shielded the runs are in that snake. I'd test the 1/4 inch runs with and without a direct box on each end, with ground lifted and without, but its hard to evaluate any damp conductor issues if you hadn't done the same sort of tests on the 1/4 inch lines when the snake was new and dry. Isn't this fun? 8) Man, I hate uninvited *Rice Krispies*. But I like knowing the snake is clean, so if I get noise, I know to hunt it down elsewhere. :) Things that make you look up and realize 10 hours just flew by. :x

I've got a dry 50 footer in a bag, in case its ever needed. Had another, but donated to a church. Having a spare 100 footer is a bit too pricey for me right now, and I haven't gigged in quite a few years. Your post just got me to flip a few latches. The old Mackie is whining for attention. Just picked up (2) XLRf to TRS wires for the output of my nephew's Behringer (to two venerable Yam 202's), and it brought back memories, but not as to price! $25 each for 6 foot cables, and not the top end either! Cost doubled in 10 years?! Sales rep says *Price of copper*. Well, good memories anyway... :) Hoping new connectors will be the end of the problems on that snake. :)

Back to the subject of the single braid dacron rope... One other thing I forgot to mention is that the strands of this rope, when unlaid, make an excellent thread for stitching the leathering on sail corners. And, being 12 strand single braid, it's much easier to unlay the strands compared to double braid. I have several pieces in my sail repair kit, waxed and ready to go. 8)

These are mounts for Harken 471 cam cleats with 424 top fairleads. On the wooden mast, I used clam cleats with fairleads and they always gave me trouble when I wanted the lines to run free. Hopefully, cam cleats won't grab the line until I want them to. I made the saddles from 10mm Meranti and drilled the oversized holes before gluing. When I glued them on, I covered the outer face with masking tape, filled the oversize holes, gooped the rest of it up and clamped them in place. Peel the masking tape when it's cured and there's an easy to work with flat mounting area. 8)

The mast is now faired (somewhat) and sealed.
The eyes in the downhaul and masthead were drilled oversized and countersunk on both sides, then filled with thick epoxy/silica. When that cured, they were drilled, slightly countersunk and rounded over to make a nice hardened fairlead.

A coat of white pigmented epoxy hides some ugliness.

The current weight should be right at 5½ lbs. I'm going to sail it a while before doing anything permanent about the snotter block location on the mast. After that is attached and paint is done, it should still come in under 6 lbs. I'm confident that it will be strong enough for the sail area and then some.

I'm afraid some of the weight savings will be offset by an upgrade in ground tackle for this boat. The 1.5 lb. folding anchor doesn't seem to have enough holding power.

Capeman, decorative weaves are available.

The way it all seems to add up to me, I think a CF mast is a little faster and easier than a wooden one. If I had used Jacques sail plan, there would not have been much need for me to make the wooden mast to try out my sail plan. I'm glad I did make the wooden spars, though. There's a few extra holes in them where I moved some of the hardware around, etc. and I sure am glad that those extra holes aren't in the CF mast.

And, the other good thing is that there's always a good excuse for me to go sailing now. "Testing the carbon fiber mast" could take several years. :lol:

That's the incentive that's driven me on this project. The weight of the wooden mast as it affects displacement is of little consequence compared to the momentum of that weight. With the force of the momentum centered 5 ft. above hull CG, the mast helps rock the boat and contributes to heeling force. Reducing that weight by half and lowering the mast CG should make a noticeable difference. With that difference and, hopefully, improved sail shaping abilities, it might be like having a different boat without the trade-in penalties. :lol:

You do some fine work Gary :) I have to tell you that you kind of inspired me to take the plunge into this carbon fiber stuff. My sleeves are on the way from Soller as well as the heat shrink tubing. I have a question for you, where did you get the intel on the post curing? I would like to do some reading on that procedure. I am not sure it is required for a small 1" shaft. Jon over at Soller said that I need to use 4 layers of sleeves and didn't mention post curing. I am probably going to send him another email about post curing but I would like to do some reading before I send it.Thanks in advance :)

Re: GK's V10

Posted: Fri Feb 18, 2011 12:38 am
by gk108
Thanks, Richard. Soller might not have much on post-curing because he sells WEST resin and their formulation, while it can benefit from it, isn't really specific about post-cure like Silvertip is. I had to round up my info from some posts here and some from S3. In January, 2010, they posted a whole lesson on post-curing on their site:
http://www.systemthree.com/sys3news/?p=218
4 layers should make for a stiff paddle. Using a higher performance resin like Silvertip and post-curing, you might be able to get by with 3 layers. I may be wrong, though. The thicker wall may be necessary for maintaining stiffness on a hot summer day. Most of the variables associated with the layup can be calculated within a certain range, but radiant heat from sunshine is difficult to convert into a constant. Better safe than sorry, especially since it's your fingers wrapped around the paddle when it breaks. :help:

Thanks for the link Gary, I have bought the Silvertip as well. I am going to build the shafts one at a time, to minimize the pain and suffering if I screw up. I was also surprised that it would require 4 layers, but that is what they told me without hesitation. If I did build one with three layers, could I add a fourth one later?

Re: GK's V10

Posted: Fri Feb 18, 2011 11:10 am
by gk108
One at a time is the best way to go. There's too much to do at once to be trying it twice. :lol:
About the only downside I can see with adding a fourth layer later is loss of wet on wet benefits for that layer. Let it cure for at least 4 days before you decide. That way, you won't be judging flexibility on resin that isn't fully cured.
Like rope, reinforcing fabrics are great in tension but poor in compression. It is the epoxy resin that must take the compression load. So, the first requirement of the epoxy here is that it be very stiff so that it does not buckle in compression.
Considering the tension/compression dynamic, 3 layers of CF should be plenty for the tension side, but may not have enough resin content for the compression side. 8)

Gk i have also read the artical and have been going over this in my head and have a question.
If i was to post cure my nv23 hull , cover the hull with plastic use a couple of heaters, get it up to temp
for two hours, wouldnt the outside glass on the outside of the hull be much cooler :?: Would you still
get the same effect on the outside glass :?: I would think the wood in the hull would act as an insulation
lowering outside skin temps.

TW, System 3 had a 3 part lesson on post curing instead ot that one page article before they changed there format. You have to get the surface of the hull being post cured to the tempurature required for it to be post cured. Also post curing isn't as effective with some epoxies as with others. For example Silver Tip is very good for post curing, System 3 and Marinepoxy don't benefit as much. I have it printed out somewhere and thought I had it saved here on the computer but can't find it right now. But basically the summary they did is about what they said without the charts and technical jargon.

Topwater, I think they want you to have airspace between the top of the plastic tent and the surface of the hull so circulation heats the outside as well.
For larger parts you can rig some black polyethylene sheeting on some ropes over than hull set out in the sun. ... If you’re inside the barn, tent with clear polyethylene and use a couple of space heaters.

TW, Gary is right on you want an airspace between the plastic tenting material and the hull. Don't know how many you would need for a hull as big as yours.

One of my cousins has accumulated a South Bend lathe and a Bridgeport vertical milling machine in his garage workshop, so I asked him if he could make some bushings and he said he'd love to make boat parts. I sent him drawings and this stock I bought from McMaster-Carr.
Image
He sent these back to me.
Image
They fit perfectly.

The setscrews at the partner will get trimmed and the foot bushing gets a pair of flathead screws near the top, countersunk below flush.
I think I'll put a coat of primer on it before sea trials. 8)

Thanks bondo. I'm glad he got the Bridgeport. It's about too big for the garage, plus it has a 3 phase motor, so there's a rotary 3 phase generator that goes with it. Just the thing for single phase suburbia. The South Bend lathe looks like it's about 10" X 36" and it's old with a 1½" flat leather drive belt. It did a damn fine job on my bushings.

Since my Dad made his career in automotive tool & die and prototype work, custom machine work ain't nothin' but a thing to me. Since he retired, my access has been limited. My cousin, Dennis worked in the powerhouse machine shops for the two big Generals, Electric and Motors, until he took an early retirement a couple of years ago. He can make a lot of stuff with that lathe and mill and he's looking for more work, so anyone who needs bushings, shafts, sheaves, slots or any of this type of custom machine work, just hit my email button and I'll put you in touch with him. Reasonable rates, no CNC setup fees. :lol:

Looks like it works fine. It does look like it has some bow in it and with only light wind, I would put another layer or two on. Really depends on your use though, for a light wind every ounce counts to win mast it looked perfect. If you want it as your every condition mast I would beef it up some more. Great looking work though.

I've been thinking about it and one thing that sticks is the way Joel solved a similar problem with his poling platform supports.
Image
I think the trailing side of the mast needs more resistance to compression, just like the inside of the curve on his supports. Right now, I'm thinking about a piece of cove molding bonded on to make a teardrop shape. :doh:

Here's some setup scrap that shows what I'm thinking about adding. The cove radius was cut on a table saw, something I've always wanted to try. 8)

I have a little bit of nice quarter sawn Douglas Fir that should be perfect for the job.

That's a tricky cut on the table saw, very cool 8) The mast will be more efficient as an aerodynamic tear drop shape than a round plan form and will better resist the bending forces, but you know that :D Masts and sails are basically the same thing as an airplane wing oriented vertically. They generate lift and need the right shape to do it. The mast is the leading edge of the sail. For best performance it's shape is important to get a laminar flow along both sides of the sail. Of course the V10 is not a high performance dinghy, but why not be all that you can be :lol:

After drawing it on paper to get the width and depth of cut, I used the calculator from here to set up the saw:

I think I'll hold off on the wing mast for now. Wing sails interest me, though. Here's something that caught my eye the other day.

GK if you look on the web a lot of the racing dinghys have quite alot of bend in the mast ,
granted its in alot heavyer air. If you wanted to stiffen it up some more couldnt you just
lay some more carbon tape down the back side of the mast :?: Just a thought.

Re: GK's V10

TW, I considered that, but it would take a lot of material to achieve the necessary resistance to compression.
I keep going back to this statement on the S3 site:
Like rope, reinforcing fabrics are great in tension but poor in compression. It is the epoxy resin that must take the compression load. So, the first requirement of the epoxy here is that it be very stiff so that it does not buckle in compression.
Bending a tube will create tension on the outside of the bend and compression on the inside of it. Since we know that the CF has practically no stretch under tension, it stands to reason that the inside of the bend, where the compression occurs, is where most of the slight deformation that allows bending occurs. Wood is highly resistant to compression applied in the same direction as the grain, but not so good with tension. If I can apply that quality (and weight) only where it is needed and get the slight benefit of the little teardrop tail at the same time, I'll be satisfied. It'll be like one stave of a hollow wooden mast. 8)

It looks like this will do just what I wanted. It takes more tha 50 lbs. of force to deflect the mast 2" in the middle.
Now I'm working on thumb cleats for the snotter block. I like this shape. Hope I can duplicate it 2 or 3 more times.

I dunno. It looks cool, but somehow seems impractical to me. There's no flat surface, so making an open top mold like the one for the rubrail end caps can't be done. In order to get all of the thin areas filled, a closed mold would require casting capabilities that I don't have. All in all, they would amount to some relatively bulky stuff sticking out from the side of the mast.
I've been looking at some other possibilities. These lacing knobs from Sailrite are looking good to me right now. For one thing, they can be moved easily if I misjudge the adjustment range I need. A piece of small stuff siezed to the rope grommet could act as a buttonhole and keep the grommet from jumping to another knob while tension is off, if that's a problem.

I guess I need help making up my mind about what to use for refinishing my brightwork. For obvious reasons, I'm hesitant to try something new, so Helmsman 1 part polyurethane would keep me in my comfort zone. I don't want to refinish very often, so maybe Perfection Plus is better for that, but I've never used it. Practical Sailor gives good ratings on it. My own experience with Helmsman is good. PS doesn't appear to have ever given any tests or ratings on the S3 paint, which should have told me something.
Right now, I'm only going to try to get the brightwork done, but it's a certainty that the rest of the paint system will experience failure by the end of this boating season. I'll be using Brightsides for the rest of the boat, just to stay in my comfort zone. 8)

We'll see how this works.

I realized that I had already been been testing this product on the O'Day and it was good for 5 years of basically full exposure. Pampered little V10 won't ever experience that kind of exposure, so maybe it will still look like this in 5 years.

And we'll see how this works, too.
Image
I'm not sure that I fully understand the effect, but I'm led to believe that these stripes increase speed. :)
They also hide the previously unpainted area where the mast rested on the rollers.

Wish I could but within the next couple of weeks I'm finally going to buy my little slice of paradise. Depending on how the extra fees hit my bank account, I may have to endure a couple more months of my self-imposed austerity. By the time I know the total bill, it may be too late to find a room anywhere near. I'm going to make a day trip down to the Cedar Key Messabout, if nothing else.

More testing of the new spars. I think they are matched up with the rest of the rig now. With the teardrop shape of the mast, I changed from spiral lacing the sail to robands. Jacques is right on the money when he recommends robands as the most controllable method of bending a sail on the mast.
http://connect.garmin.com/activity/84423075
Lots of puffs and lulls, breeze curling around points of land and gator wakes which rhymes with freighter wakes. I spent most of the afternoon working my way upwind so I could make a nice downwind run with the boom swung out past 90° for some downwind lift. Dunno why I'm the only one I ever see sailing a boat on Lake Seminole. :doh:

Some stills from the tillercam video:

It was a sunny day.

Note the wrinkle in the sail at the first grommet below the head. I tied the roband at the head too tight. Not only did it make the wrinkle, it also made the leech cup more than normal, even though it's hollow cut to prevent cupping. Next time, no roband at the head.

Here's the video. Pretty boring, a few tacks and most of a furling at the end. 8)
