ABSTRACT:
Improvements made to a router relates to a plunge router depth stop system. The depth stop system comprises a depth stop rod contained within a restraining collar coupled to the router housing. The depth stop rod is configured both to rotate at a fixed height above the router base and to slide up and down within the collar in order to adjust its height above the base. At an upper end of the depth stop rod, a turret knob permits an operator to rotate the rod within the collar. At the other end of the rod, a protrusion portion selection member is located to engage selectively one of a plurality of step-wise rising depth stop position surfaces located on the router base. When the protrusion portion selection member is aligned vertically above one of the depth stop position surfaces, the motor housing will plunge until the protrusion portion selection member engages the depth stop position. The operator sets the depth stop height by placing the depth stop rod at the desired height and tightening a restraining collar. Once configured in this position, the motor housing can be repeatably plunged to a desired position. The operator can selectively step the depth downward by keeping the depth stop rod at the desired position while rotating the rod to align the protrusion portion selection member to another depth stop position having a different depth stop height.
