ABSTRACT:
Apparatus for guiding the movement of a hand held router relative to a workpiece comprises a support forming an upwardly facing base adapted to underlie and support a workpiece to be routed. A plurality of parallel guide posts extend upwardly from the support and carry a rigid frame having an open central portion. The frame is mounted on the guide posts for guided sliding movement toward and away from the base to overlie a workpiece supported on the base. Springs bias the frame away from the base and clamps act to overcome the bias and clamp the frame into engagement with the uppermost surface of a workpiece supported on the base. A router guide template is removably connected in the open central portion of the rigid frame at a location to substantially engage the uppermost surface of a workpiece support on the base when the frame is clamped into engagement therewith.
