Abstract

A base plate for mounting a router in a support table provides a plate configured to fit in an orifice, having an inwardly extending ledge thereabout, defined in the support table with the router supported by the base plate to depend therefrom. The base plate defines a medial orifice for passage of the router shaft through the orifice for operative positioning of a cutter carried on the router shaft above the base plate. The base plate medial orifice releasably carries plural annular inserts to cover space between the router shaft and the support plate portion defining the medial orifice. Plural adjustment screws are carried in threaded engagement in the ledge of the support surface orifice for vertical motion to adjustably move adjacent portions of the base plate periphery upwardly from the ledge to create a coplanar relationship of adjacent portions of the base plate and support table. The base plate carries at least one releasably adjustable fastener to fasten the support plate on the ledge in the orifice defined in the support table.

Dependent claims

A base plate, for mounting a powered hand manipulatable router having a shaft carrying a cutter in a horizontal support table defining an orifice having an inwardly extending ledge about the lower portion of the orifice to receive and support the base plate, comprising in combination:

a base plate configured to fit in the orifice defined in the support table with at least a portion of the peripheral edge of the base plate supported on the upper surface of the ledge extending inwardly about the support table orifice, said base plate defining an orifice to allow the passage of the router shaft through the orifice and spacedly above the base plate to operatively carry a cutter above the base plate;
leveler means carried by the ledge about the support table orifice to contact the base plate to vertically move the base plate relative to the support table responsive to motion of the leveler means,
at least one fastening means carried by the support plate adjacent the periphery thereof including a bolt, depending through the base plate and spacedly therebelow, carrying an elongate fastening dog to contact the support table and a threadedly engaged nut outwardly of the fastening dog to move the fastening dog toward the base plate to fasten the support plate in the support table.
