ABSTRACT:
A step gauge for setting up wood working power tools. The gauge has a planar surface on which a series of measurement steps is arranged in opposition to a reference edge. The surfaces of the steps are located at known fixed distances from the reference edge. In use the reference edge is placed against the table, fence or guide of a wood working power tool. When the tip or side of the blade or bit is rested against the edge of a given step the associated known fixed distance becomes the desired measurement. Specialty notches are provided interspersed with the series of measurement steps in order to allow the setup of specialty lumber processing; in the reference edge to permit the setup of joiners; and in the reference edge in aligned opposition to one of the measurement steps to function in cooperation with the reference edge as a square.
