[QUOTE="davedude, post: 433024, member: 17211"] Welding a stack of aluminum square tubing sounds like a great idea to me. Very strong! I am working on my third plywood transom attempt which unless I dorf it somehow looks like a go. First "prototype" was two 3/4" exterior plywood glues with titebond 3 and screws. Bad batch of plywood---many voids and delaminating without exposure to water! Second "prototype" was three 1/2" exterior aracoply (no voids) laminated with Raka epoxy resin and biaxial fiberglass cloth. Did not get enough epoxy between one layer and made some bad cuts (not 90 degree) with a cheapo jig saw. Third attempt looks like a success. Went with a slower hardener for the epoxy which gave me the pot life I needed to make sure everything was gooped up and wetted out completely. Bought a nice Bosch jigsaw that cuts at a square 90 degree thru 1.5" of wood and made the finishing cuts last night. Now I am wondering if I should seal with this awesome Raka epoxy or do the traditional old school seal and paint. Best of luck to you. [/QUOTE]
