Re: C17 open 'Fair Enough' in France

Post by OlivierP »

Good points, thanks, access is indeed an issue, but I thought it would be better to run the tapes in one piece over the bottom and both side panels, especially at the bow - or would you tape the upper panel separately ?

Structurally speaking it doesn’t matter either way. Tapes with an overlap are strong as one continued tape.

One thing I see a problem with is the taping of the chine seams with tape sine you left the sides extended. Hou are you going to get 2 or 3 layers of tape offset on the hull and side.

I think the plan is to fill before rounding to 13mm and glassing over. One trick I learned is that the first layer of tape tends to lay better if you put down some slightly cabosil thickened epoxy underneath first.

Yes I'm filling the chine flats with scrap plywood pieces, epoxy and wood flour, I'll round the edges, tape and glass over them.

Looks ugly right now, but I was in the middle of gluing scrap plywood. It will be flat eventually, as it should be for chine flats...

Thanks Dan.

More filling of the chine flats, still not flat but getting closer. They go all the way to the front.

Assuming that new layers of fill are going on before the old fully cures, I'd put some microballoons in the last to help the sanding process before you glass. Alternatively, a grinder with 24grit will do it.

Thanks Oneway, I managed to sand what I needed with 40 grit.

Now the tape is on the bottom, transom and chines. It went well around the chine flats after rounding the edge.

Also some progress on the console.

The project will be on hold for a week as I go fishing...

Back to work, the bottom is glassed and the upper side panels are glued. Hull complete ! Well, still a long way ahead.
