ABSTRACT:
A mechanism that attaches to a plunge router, particularly when the router is used in a router table, to conveniently and accurately move the router body relative to the router base in order to adjust the position of a router bit in the router relative to the router table. Substantial excursions are made by moving a handle up or down using a handle or a foot pedal, and small excursions are made using a micro-adjust mechanism that has a detent set screw and cooperating structure to facilitate adjustment of the micro-adjust mechanism by very small predetermined increments.
