Thank you both!
I think I got it.. no resin till it's all glued in. I'll use PB between the hull and the first 1/4" piece and then Tightbond III on all the subsequent layers. Then 1708 on the outside of the completed laminated transom.
wog, I planned on using two or three clamps like you showed in the stickies in the middle where the splash well came from. I realize now why you suggested I cut the whole rear cap off and not just the splash well like I did... but I guess hindsight is 20/20. :joyous:
Now I was thinking that if I clamped the center section the outer "wing" sections, since the transom is curved in towards the middle, would tend to press themselves to the hull without a lot of exterior clamping. I'll add a picture of what I thought of trying to do... the two outer pieces (outlined in blue) really only support the two tie down cleats (I'm guessing that's what they're called... they're U shaped metal brackets that tie straps attach to the boats rear hull and to the trailer when transporting the boat) and the swim platform. The curved pieces of 1/4" plywood making up the main transom is the part outlined in red. The center part would be clamped where the splash well has been cut out, and the outer wings would (hopefully) press themselves into the hull due to its curved nature. Does that make sense? If so, do you think that would work?
If not the other alternative was to build a support in the boats interior and then use bottle jacks to put pressure one those outer wing portions of the main transom.
I'd love to hear your thoughts.
