(Please forgive the messy garage). The cars have been exiled to the driveway for the duration of the build so clutter tends to pile up.
I did some looking today for 1/8 inch birch ply and found nothing aside from dumb looks from DIY store clerks. Will 1/4 inch work for a Generic Benroy profile for the roof? I am wondering if it will make the bend. I know I can order 1/8 inch but the freight on a few sheets of plywood is astronomical.
