Abstract

A plunge router constructed for mounting beneath a work table has a base adapted to be connected to a work table and defining a central opening, a router head assembly comprising a drive motor, a drive shaft, a collet and a housing, a plunge guide assembly supporting the router head assembly for movement toward and away from the base, a retracted position adjusting mechanism coacting between the base and the head assembly for blocking movement of the head assembly to a first default position from a second, adjusted retracted position and comprising a threaded force transmitting member fixed to the base and projecting toward the head assembly, an abutment element projecting from the head assembly transverse to the direction of extent of the threaded member and an adjustment member threaded to the force transmitting member and engagable with the abutment element to adjustably change the head assembly second retracted position. The head assembly also includes a second head assembly abutment element. The plunge router of the present invention further comprises a precision adjustment mechanism for moving the head assembly a precise distance from the second position to precisely position…
