ABSTRACT:
A sub-base is provided for a router adapted to engage a stationary guide while cutting a workpiece. The sub-base includes a plate and an elongated guide-edge. The guide-edge extends from a linear edge of the plate in a manner as to lie in outboard shielding relationship to the router base. The sub-base further includes means for detachably securing the plate to the base with the guide-edge outboard of the base. The plate is positioned such that a generally planer surface of the plate engages the workpiece and the guide-edge extends to engage the stationary guide. The router bit extends through a central opening in the base and further extends through a central opening in the plate of the sub-base to cut the workpiece.
