Another method of setting the tool is with a gauge as in [Fig. 991], which sets it true with the angle independent of whether the angle is true with the side of the tool or not. In [Fig. 992] is a form of gauge that will serve to grind the tool by to correct angle, and also to set it in the lathe by the angles, independent of the side of the tool.
