Abstract
Improvements made to a router relate to a plunge router locking system. The locking system comprises a locking arm lever coupled to a threaded member arm which engages a plunge guide post to hold the router motor housing at a desired height above the router base when the locking arm member is in the locked position. When the locking arm member is moved into an unlocked position, the motor housing can move up and down the plunge guide post, where the motor housing is opposed by a bias system comprising a compression spring to prevent the motor housing from free-falling into the router base. Additionally, the locking arm lever can be held in the unlocked position with the use of a mating coupling member attached to the motor housing in order to keep the plunge locking system in an unlocked position.
