I need a 12-foot by 8.5" piece of 3/8" ply. The box stores only carry
8-foot ply stock. Already I have a 4x8' sheet of 3/8" ply. Is it
possible to make a 12-foot piece? I have most common tools.

I think I remember that 6:1 or some ration like that works. Make a ramped
jig that allows you to use a router.
