Abstract
Improvements made to a router relate to a fine adjust depth stop system. The preferred router comprises a micro-adjust knob coupled to a threaded member within one of a plurality of plunge guide posts. A depth stop nut is coupled to the treaded member such that the nut travels up and down the threaded member as the mirco-adjust knob is rotated. The location of the nut within the plunge guide post defined a depth stop position for the motor housing relative to a router base. When the motor housing is located at the depth stop position, the stop point, and thus the motor housing, will move up and down relative to the base as the micro-adjust knob is rotated.
