Abstract
Improvements made to a router relate to a sub-base alignment system. In a preferred embodiment, the alignment system comprises a plurality of raised bosses which are located on the sub-base at known locations and which engage a plurality of recessed cavities in the router base. Alternatively, the raised bosses may be placed on the router base and the cavities may be located in the sub-base, or a combination of boss and cavity locations may be used. The router base is positioned at a known locations relative to the center of rotation of the router bit. For example, in the plunge router shown, the base is coupled to plunge guide posts, which themselves are coupled to the motor housing at known locations. The coupling of the raised bosses with the recessed cavities places the sub-base at a known position relative to the router base. In such a configuration, the outer edge of the sub-base, which may be used to guide the router when making a cut, is held at a known position relative to the center of rotation of the router chuck, thus enabling the precise guidance of the router relative to a guide member.
