Claim:
A router comprising: a base for supporting the router on a work piece surface; a motor housing coupled to the base for movement along a first axis relative to the base; a motor supported by the housing and operable to drive a tool element; a cantilevered shaft rotatable about a second axis and oriented substantially parallel with the first axis and offset from the first axis, the shaft including a first end coupled to the motor housing; a second end; a threaded portion between the first and second ends; and a lock mechanism at least partially received within a receptacle in the base, the threaded portion of the shaft engaged with the base through the lock mechanism; wherein rotation of the shaft about the second axis causes movement of the housing relative to the base along the first axis, and wherein the lock mechanism is movable within the receptacle in a direction substantially normal to the second axis between an engaged position, in which the threaded portion of the shaft is engaged with the lock mechanism and the base, and a disengaged position, in which the threaded portion of the shaft is disengaged from the lock mechanism and the base.
