Abstract
A safety tool rest for a lathe having a rotating workpiece is disclosed. The tool rest includes a generally planar base which is attachable to the lathe. An elongate flange projects upwardly and outwardly from the base and has an upper edge which is disposed adjacent the rotating workpiece. A tool for cutting the workpiece rests on top of the upper edge of the flange. An elongate bar is attached to the base but is located above the base at a height higher than the upper edge. In this manner, the tool is inserted below the bar and over the upper edge for cutting the workpiece. The tool is prevented from being flipped about the upper edge during contact with the rotating workpiece by the bar. Preferably, the bar is vertically adjustable relative to the base to accommodate different sized tools. This adjustment is provided by two threaded bolts which pass through the bar and engage the base. A spring is provided around the bolts to urge the bar away from the base.
