ABSTRACT:
A depth of cut adjustment mechanism for a power planer including a double threaded elevation adjustment bolt (40) extending downwardly into threaded engagement with a stem (32) extending upwardly from the front shoe (16) of the planer (2). Rotation of the bolt (40) is controlled by a knob (20) attached to the head portion (54) of the bolt (40). The knob (20) has associated therewith a scale (41) which is readily calibrated so that a zero reading on the scale corresponds to a zero depth of cut. The adjustment mechanism further provides a positively located park position wherein the front shoe (16) is extended downwardly beyond the cutting blade (8) to effectively elevate the cutting blade (8) so that it does not mar the surface upon which the planar (2) is set when not in use.
