Abstract
A buffing apparatus has a shaft assembly connectable to a drill or other stationary motorized buffer/polisher. A stator is fixedly mounted on the shaft and a rotor is rotatably mounted on the shaft, and each of the stator and rotor includes a respective hub and two or more arms extending radially from the respective hub, and each of the two or more arms defines a hole. A pad having first and second holes is mounted on the shaft with an arm of the stator extending through a first hole of the pad and an arm of the rotor extending through a second hole of the pad. The pads are secured in place with a connector extending through the hole of an arm of the stator and through a hole of an arm of the rotor so that the pads are sandwiched between the shaft assembly and the connectors.
