Bending plywood for roof
I'm installing new 7/16 plywood on the roof of a trailer. The framework in the roof is flat and then angles down a few degrees near the edge (as opposed to having a gradual curve all the way across). ...

forgo the 7/16 single sheet of plywood and instead use two thinner sheets of plywood laminated in place. Thinner sheets will bend and conform much easier than one thick piece and will be far stronger, faster and safer than sawing a lot of relief cuts to the underside of the plywood.
Not sure why I didn't think of this, but it is much easier. Might cost a few $$$ more, but it will save a lot of grief.
Laminating is how it is done for this kind of bending application.
Thicker wood unless steamed (not good or recommended for plywood due to water based glues used) must have relief cuts which compromises strength for small radius bends.
I would skip the 1/4 plywood, 1/4 plywood typically has a lot of voids and coarse grain, use Luan, has much finer grain and virtually no hidden voids than 1/4 plywood, which also means more strength and less chance of breaking or snapping in the wrong place.
Overall Luan a better product to work with.
