I bought part of a sheet of 3/4" GIS plywood with an oak veneer, approx. 18" wide. I have fashioned it into a floor to ceiling door for a bathroom cabinet by adding a handle trim to one edge. I have four euro hinges spaced down the length of the door.
The problem is the plywood seems to have a bend in it from top to bottom. In the middle of the door the variation is approx. 1/2".
How do I get rid of this bow? I am afraid to damage the layers.
