I am making a walnut corner cupboard. It has a glazed upper door with 15 panes of glass. It measures 23" wide , 45 3/16" high, and 15/16 thick. I made it out of quartersawn stock thinking that it would be very stable, but it wasn't. The right side(hinge side) bows inward about 1/32 which isn't too bad. The left side(lock side) bows inward 5/64. When I place the right(hinge) side flush with the cupboard and bring the left(lock) side out to where the bow in it is flush with that side of the frame, the bottom left corner kicks out 5/32 and the top corner 3/64. Any suggestions as to how to deal with it besides some serious hand planing at the areas where it protrudes. I am also concerned about it moving again when all the glass is put in. Thanks for any help you can give.
