ABSTRACT:
A dual action apparatus has a body with first and second ends. A shaft extends from the first end. The shaft is adapted to be received by a drive motor. A cavity is formed in the second end of the body. The apparatus also has an inner shaft, with inner and outer ends. Bearings are received on the inner end of the inner shaft. The bearings and the inner shaft are located within the cavity of the body such that the longitudinal axis of the shaft is offset from the rotational axis of the body. A retainer ring is used to retain the inner shaft and the bearings inside of the body. The outer end of the inner shaft receives a sanding pad or a scraper blade. The scraper blade has an opening through the blade, which opening receives the outer end of the inner shaft. A nut retains the scraper blade onto the inner shaft.
