Abstract
A bi-directional grinder for allowing an operator to change the direction of rotation of the wheel, having a housing, a motor capable of bi-directional rotation, and a shaft. The grinding wheel is mounted on the shaft within a shroud and attached to the shaft with a locking mechanism. The shaft has a left threaded bottom portion and a right threaded bore therein. Once the grinding wheel is positioned on the shaft, a nut is tightened onto the threaded bottom portion of the shaft to tighten the wheel against the shoulder. A bolt with a broad head is inserted into the shaft bore so that the broad head is tightened against the nut. A spring loaded pin extends through the housing and is mateable with an off center transverse hole in the circular gear. When aligned, the pin may be inserted into the gear hole to cause the gear and shaft to cease rotation.
