Got some epoxy and plywood rounded up. Built a work table. Next order of business is scarfing the plywood.
Bottom is from 2 sheets of 9mm (3/8") Okuome. Sides are from 2 sheets 6mm (1/4") each side. 3 scarfs total.
2 sheets of 9mm clamped to work table, then beveled with belt sander.
Put bevels together, glue and clamp.
Sand the scarf flat to get a 16' sheet of plywood.
