ABSTRACT:
A setback gauge for use with a router, a fence and a workpiece, the router having a base, an edge on the base for guiding the router, and a router bit extending out from said base for rotation about a router axis. The setback gauge comprises a substantially rectangular plate wherein the length of the rectangular plate defines a first setback distance and the width of the rectangular plate defines a second setback distance. The first setback distance is equal to the distance from the router axis to the edge of the base plus one-half of the cutting diameter of the router bit and defines the setback distance for cuts inside the cutting line. The second setback distance is equal to the distance from the router axis to the edge of the base less one-half of the cutting diameter of the router bit and defines the setback distance for cuts outside the cutting line. A set of setback gauges includes a plurality of identical pairs of setback gauges for use with various common router bit cutting diameters.
