How to bend a sheet of plywood.

This product 8 x4 will stand 4 tall and wrap around like a barrel. The difference between 4 x8 and 8 x4 is the direction in which the board will bend. It could take several days for the plywood to become soft enough to bend. It s helpful to know how either for making skateboard ramps or something bent.

Actually there s a lot of projects that you can implement th. Radius bending plywood purebond 1 8 8 x4 2 ply cross grain rotary peeled tropical hardwood back.
