Re: Radon Transom Replacement
The guys are giving good advise if you are looking for the most strength for the amount of material used. But the are a zillion boats out there built with plain old mat and roving over their stringers that are 30-60 years old and still going strong. You just need to pick what works for your needs.
Re: Radon Transom Replacement
Thanks all, I appreciate all the discussion. I have epoxy and 1708 right now so that's what I will be using. It doesn't sound like doing anything else is really worth it... Going with different fabrics might create a "stronger" layup if done perfectly but I don't need to go to that level, I' can always just add "more" if it needs it.
I think one issue is I just don't realize how strong fiberglass is. I had a mechanical engineering friend who always said if you're building something out of metal and it looks strong enough to you it's probably 3x what it needs to be Somewhere on here one of the guys said something like 3x3/4" ply X 7" tall and three layers of glass makes a stringer strong enough for a much bigger boat....

Re: Radon Transom Replacement
I'm only explaining you don't need to buy uni if you have 1708.
Yeah. A 250 word essay, but same answer in the end.
Use what you have unless it is way wrong and drinks resin to no benefit.

Re: Radon Transom Replacement
Because fiberglass is so limber by the time you get it stiff enough to do the job it is way overkill on the strength part. That is what makes using a core so good, be it wood or something else the spread makes it stiff with a lot less glass.
Re: Radon Transom Replacement
Thanks guys. Well this is the kind of garbage I am dealing with in the demolition. You all haven’t talked about when it’s appropriate to pour in pools of plain resin….. It’s really difficult to get that out, it’s in next to some of the stringers mostly.

Re: Radon Transom Replacement
Many builders might use a skilled glass guy to shoot the gelcoat and lay in the first layer of mat but then turn it over to a minim wage guy with a chop gun. Years ago the materials were cheap so using extra was no big deal. This is why it is hard not to end up with a better boat when it is built by someone who is doing it for themself.
Re: Radon Transom Replacement
Changing topics a little, when do I put the limber holes/drainage holes in the stringers? Before or after I tab them in?
I have some round fiberglass tube I was thinking of using. I can over drill a bit and bed those in to seal the wood. I’m not sure if that’s a good idea.
Suggestions or comments please….

Re: Radon Transom Replacement
I find it much easier to do it while the stringer is upside down and I can see things well.

Re: Radon Transom Replacement
Easy. Anytime you feel like spending money to make the boat heavier with no increase of strength.

Re: Radon Transom Replacement
Just cut notches and lay on some epoxy and a piece of 1708 or use the tubes. Main thing is to seal up the limbers so they don't suck water.
