Abstract
A power tool cutting guide for making plural parallel cuts or arcuate cuts in a workpiece has a member, rotatable within the circular track of a frame, which can be fixed in any angular orientation relative to the workpiece, a guide assembly joined to the rotatable member on which a tool support plate can slide between positionable stops, and a ratchet arm with an attached pawl which engages the serrations in a rack so as to incrementally move a workpiece along a fence. The guide also features a spring-urged retention arm which holds the workpiece firmly against the fence during cutting and means for automatically withdrawing the cutting tool from the workpiece surface upon completion of the cut.
