I need to make a custom mounting pad for my trolling motor and need some 1 1/2 to 2" thick marine plywood, about a 10" x 10" piece. Does anyone know where I could get such a piece w/o having to buy a big sheet? I would also be willing to laminate two 3/4 to 1" pieces together. If someone works at a place where they scrap this size, that would be the perfect solution. I'm on the west side of Portland but get around the metro area as part of my work.
