Abstract
A simple and quick manner for centering a sub-base of a fixed-base router. The sub-base is provided with two sets of peripheral holes and a large central opening. One set of holes is countersunk and receives flat-head screws; the other set of holes is counterbored and receives pan-head screws. The router is sent from the factory with the sub-base attached by the flat-head screws. To center the sub-base the flat-head screws are removed and the pan-head screws are inserted to loosely mount the sub-base. The counterbored openings are oversized to allow lateral movement of the sub-base. A cone element is installed in the collet and engaged with the sub-base through the central opening. The cone element fully abuts the opening to center the sub-base, the pan-head screws are tightened and the cone element is replaced by a router bit.
