Abstract
A rotary surface finishing tool includes a generally circular body of a finishing material, such as polymeric foam, the peripheral edge of which is wrapped around the outer edge of a circular cup-shaped backing plate. The plate is subsequently crimped over the edge of a locking ring to capture the edge of the foam material therebetween. Other types of finishing material, such as tufted wool, including a backing with a flexible peripheral edge can also be mounted to a backing plate using the crimping techniques described herein.
