2122621 9308970 PCTABS00021 A router (200) having a depth of cut adjustment mechanism including an adjustment ring (226) which engages a screw thread (218) on the motor housing (202) and rotationally engages the router bas (208). There is further provided an arrangement for preventing relative rotation between the motor housing (202) and the base (208). The adjustment ring (226) is formed as a split ring with projections (236, 238) adjacent opposite sides of the split, each with a frusto-conical camming surface (252, 254). A circular clamp knob (246) having a plurality of tabs (294) extending axially outward from a top surface and radially outward from a central axis is mounted for threaded rotation on a bolt (244) passing through the projections (236, 238) radially with respect to the router motor housing (202) which bears against the camming surfaces (252, 254) so as to squeeze the ring (226) in order to effect a clamping action as the knob (246) is moved inwardly. |
