Abstract
A base block is provided having a pair of laterally spaced, downwardly facing and constant radius arcurate bearing surfaces generated about parallel axes lying in a reference plane. A shank assembly including an exposed shank portion is mounted from the base block for oscillation about a third axis paralleling the aforementioned axes and with the exposed shank disposed and swingable in a plane normal to the third axis. The block and shank assembly include co-acting indicating structure operative to indicate when the shank assembly is rotated about the third axis relative to the base block to a position with the exposed shank disposed normal to the aforementioned reference plane.
