We make four piece solid wood drawers with planted false fronts. The corners of the four piece boxes are joined with multiple splines in contrasting wood. After the splines are glued in and dry, they are sanded flush on a Lasm oscillating edge sander.
My concern is that the edge sander seems to round the drawer front slightly and it then shows when it is screwed to the false front. The steel pad is straight and there is graphite on the pad. Has anyone experienced this problem?
My possible explanations are that the pad is thin and very tall (10 inches) and that it may be flexing when pressed. Also I wonder if pressure compresses the graphite slightly and then as the sander oscillates, the belt comes out slightly above and below the drawer and this rounds the front slightly.
I was considering clamping the drawer to a sliding table on bearings so that the drawer could be ever so lightly touched against the belt, as no pressure would be necessary to control it.

I am not sure that I follow your description of your drawer construction, but if I do... Think about sanding the drawer with an Oakley drawer sander after the front is attached. The Oakley will get into the corner where the side meets the front and make a nice clean corner, plus it will sand the length of the side. It also assures that all lips are of the same thickness, so the drawers are all flush with each other when inserted into the case.
