I wish there was an easy way to get thin lumber to laminate like that. One guy on the Wooden Boat Forum laminated kayak-proa akas out of plywood. I sent a message to ask how they worked out, but I never heard back.
The main point of curved lamination - especially in this case - is to have all the strength and stiffness of the wood fibers working for you. Veneer core plywood has almost half its layers running cross-grain; while the assembly might look similar, the strength would be lacking.
I made hollow curved akas with 6mm ply sides and 10mm top and bottom ripped from 1" stock. But I wonder if 1 or 2 layers of ply would do instead? Stress is mostly longitudinal anyway in the outer surfaces of a beam?

ReplyDeleteI plane pine down to 6-7 mm and this bends quite easy but the glueing this up is a mess and take a lot of glue.
