Abstract
The present invention is a tool for renotching a worn trowel. The invention consists of a grinding wheel adjustably mounted on an adjustable plate. The edge of the plate is provided with adjustable fingers for engaging the notches of a trowel to insure consistent spacing and depth of notches being formed in the trowel when grinding with the tool. The grinding wheel is attachable to an electric drill or similar motive device for rotating the wheel to thereby accomplish the grinding needed to renotch the worn trowel. The tool is provided with a handle for gripping the tool.
Claims8
A tool for renotching a trowel comprising:
- a v-shaped grinding wheel having two cutting sides that grind simultaneously to create a symmetrical v-shaped notch in a trowel;
- said grinding wheel rotatably mounted on a hand-held mounting plate such that a longitudinal axis of the grinding wheel is oriented approximately parallel to a front edge of the mounting plate, means for aligning an edge of a trowel relative to a front edge of the mounting plate so that the grinding wheel engages and grinds notches into the edge of the trowel as the trowel is advanced toward the tool-mounted grinding wheel, and means for rotating the grinding wheel so that the wheel grinds notches into the edge of the trowel as the trowel advances toward the rotating grinding wheel.
