Buddy of mine works for Alcoa so i get 200 lbs per year at scrap price. I can get 1/4 inch aluminum but not the square stock. I'm no engineer but I've gotta believe a frame can be made then tied in with that 1/4" thick aluminum. Just trying to decide if it's worth it versus just putting marine plywood back in.
So I'm curious George. Did you consider not using 3/4 plywood and just building an aluminum frame out of aluminum square stock? Then cover the framework with the 1/4 inch aluminum? I'm considering getting away from the plywood completely and wondering what I'd need to do back there structurally to make it happen.
Wisdom may come on little cat's feet but in so doi

This is the other side of the transom. It is quarter in alum sheet in front of new 3/4 in marine plywood. - which is up against the original (thin) transom I cut a "gasket" out of commercial rubber roofing; with the plywood sandwiched in between- as the plywood would eventually corrode the alum.
The "bracket" was also fabbed out of 1/4in alum and 2in alum angle.
You cannot see the extensive bracing that was done at each rear corner- which was four in alum angle with grade 8 7/16 bolts throughout. Stainless would have been preferable but I was bleeding $$$ like a stuck pig between the boat & trailer

George, I must have watched these videos a couple dozen times each. I even made a playlist in YouTube and watched them in a loop for 30 mins on my 55" TV. What a beautiful boat you have. I can't wait to see it with triples.
