ABSTRACT:
A backup pad for engaging and supporting abrasive sheets, the backup pad being mounted securely to a drive shaft to prevent relative rotation thereto, and to allow easy mounting and dismounting of the backup pad to the mounting shaft without the use of tools. The backup pad includes a body comprising a front surface and a back surface, releasable engagement means provided on the front surface for releasably engaging an abrasive article, and a mounting boss provided on said rear surface. The mounting boss includes a first end facing away from the body, and an opening in the first end of the boss, the opening being formed by an inner surface generally perpendicular to said body and defining a non-circular cross-section. The opening includes elastic means such as an o-ring for releasably engaging a drive shaft mounted in said opening. Also disclosed is a method of using such a backup pad.
