Abstract
The height adjustment ring assembly is provided for adjusting height of a router motor housing relative to a router body, the router being movable between upright and inverted positions. The housing includes external threads formed thereon. The height adjustment ring assembly comprises a support member secured to the router base, the support having a radially extending flange portion. An annular adjustment ring includes an internal thread for cooperation with the external threads. Means for entrapping the flange portion with respect to the adjustment ring is provided, thereby limiting relative axial movement while allowing free relative rotation of the adjustment ring with respect to the support member for adjustment of the router motor housing regardless of router position. First and second zero reset rings are rotatably secured to the adjustment ring for relative rotation with respect to the adjustment ring, each reset ring having indicia formed thereon to facilitate accurate adjustment of the motor housing with respect to the router base in both the upright and inverted positions.
