Abstract
A router assembly including a router sub-assembly vertically adjustable relative to a supportive base plate through the utilization of a sub-assembly supported rack gear and a pinion gear meshed with the rack gear and journaled from the base. The base includes a handle portion for horizontal directional control of the router assembly during routing operations and oscillatably supported from the base. Connecting structure operatively connects the handle portion and the pinion gear for oscillation of the latter in response to oscillation of the former, whereby adjustable oscillation of the handle will be effective to vertically adjust the router sub-assembly relative to the base plate.
