I made a rack at 20 degrees from vertical and use a piece of mdf to support the plywood the full length. I remember reading somewhere that the maximum angle from vertical is 10 degrees. My plywood stays in decent shape. I cant post a picture right now because this computer doesnt have the picture.
My ceiling is only 8 ft and it is difficult postioning the sheet on the rack. I am going to make a cart to store my plywood and store it horizontal like Allen's link shows. Then I can store the plywood in my cold storage area and it leaves some more floor space for something else.
Is it OK to store plywood in the cold and use it right away? Or does it have to aclimate like lumber?
