Abstract
A depth of cut adjustment mechanism for a portable power planer having an adjustable front shoe whose elevational position controls the depth of cut of the tool. An S-shaped rod is fastened at one end to the adjustable front shoe and is threadedly engaged at its other end to an adjustment nut rotatably mounted in a race formed in the housing. A control knob having disposed thereon a scale referenced to a mark on the housing is secured to the nut so that rotation of the control knob causes a corresponding adjustment in the elevational position of the front shoe. A tension spring is connected between the front shoe and the housing to cancel out inherent tolerance play between the front shoe and the housing.
