I just made a drawer box for one of my cabinets. the drawer box is very square but the face frame must be off some because the left side of the drawer sticks out almost a 1/8" more than the right side. Moving the back of the left slide didn't help much if any. can I sand the front of the box to compensate for this or will it be noticeable some how,. I figured if i beveled the box onthe front so the left side was 1/8" thiner the drawer front would sit flush on the frame.
