I need a four-foot by eight-inch piece of very stiff ply, but with a slight curve. Given that I can't induce curvature in wood fabricated specifically to resist it, I'm going to try making my own.
The fact that I happen to have a four-foot by two-foot sheet of cheap 5mm ply which already has a suitable bend in it, is a happy coincidence.
It isn't quality plywood, but I'm thinking that the coats of epoxy which will be necessary to glue the 'plies' together, can provide pretty good encapsulation if I take care to coat the end-grain. Also, it won't often be immersed (I hope).
I'll end up with a piece 4ft by 8", about 16mm thick. Or I could cut four six-inch strips, to make a thicker 'plank'.
It needs to be rigid and robust because the plan is to mount an outboard bracket on it. A bit hard to describe till it's done.
Any advice or experience of similar jobs? Thanks.
