Bending Plywood for GF-14 Hull

mpmlaw · Post by **mpmlaw** » Fri Oct 03, 2008 9:44 am

I have glued the bow transom and aft transom onto the side panels of my GF-14, along with the frames for the mid-seat.

However, the plywood sides are bending inward (concave) at the bow transom, not outward like they should in order to be able to accomodate the front deck piece.

Does anyone have any ideas on how to achieve the proper bend of the plywood side panels without cracking/breaking the plywood?

Thanks,

Pat

Weird.
Can you post a picture? Is it shaped like an S?

Is the forward frame in place? What happens if you slide it in? Bow transom isn't upside down is it?

The forward frame is not yet in place. When I dry-fit the forward deck, it wedges up against the sides without making contact with the bow transom.

The sides do form an "S" shape, tapering in toward the bow.

Look at the building notes:

You must insert the other frames before the deck.
The frames will shape the sides.

O.K., Thanks.

I may have been getting ahead of myself. I'll be working on it this weekend and I'll see how it goes.

I'll e-mail you if we have any problems.

Don't worry about the deck until all the frames are in. I've built the GF12 and the GF16 and they both fit like a glove. I'd have to think the 14 would also.

I had the same problem on my GF14 I found I didn't have the correct measurement on the forward seat frame was short two inches.After the fix all was OK. You didn't mix up the two center frames??????

I spent this morning correcting the problem with the bow.

As it turned out, I think what happened is that I cinched the wood screws too tight at the bow and this caused the side panels to not want to "bow" outwards the way they are supposed to. Additionally, I don't think I had sufficient support under the bow transom while the glue was drying which caused the side panels to bear the weight of the bow transom while the glue is drying, naturally causing the side panels to taper inwards rather than bow out.

I popped the side panels off the bow transom and re-glued them this morning (fastening them much looser to the transom than before) and the problem seems to have been corrected.

Anyway, I thought I'd post this so that maybe someone else might be able to avoid the same mistake. It's not a big deal, but it is easy to avoid.

Thanks for the input.
