Abstract

A system for abrading irregular surfaces includes a bracket that can be attached to a shop aid. The bracket carries two motors to which abrasive pads are attached, and the positions of the motors are controlled to move abrasive elements over the surface to be abraded. The abrasive pads are attached to abrasive-pad backing of different configurations. Disclosed configurations are generally flat, triangular, and U-shaped.
