Particularly with today's thin veneers, it's tough to sand flush an edge band without sanding through the veneer.

This simple jig does the trick. Remove the plastic router base and screw on a piece of 14 " hardboard as shown. Adjust a 12 " straight router bit flush with the bottom of the hardboard. Keep the router absolutely vertical and it will cut away any material not flush with the jig.
