An auxiliary base plate assembly for converting a portable power tool such as a router having an integral base plate and a pair of parallel guide rods affixed to the integral base plate and extending laterally from opposite sides thereof to a stationary bench-type power tool including: a work bench having a first through vertical opening in its top surrounded by an inwardly extending peripheral flange recessed below the top surface of the work bench by a predetermined distance; an auxiliary base plate member having a thickness equal to the predetermined distance and having a centrally located, vertically extending, second through opening and a pair of parallel, horizontal through bores intersecting the second through opening and positioned to receive the ends of the power tool's guide rods wherein the second through opening is shaped to receive and surround the power tool's integral base plate so as to permit mounting of the auxiliary base plate member on the power tool by insertion of the guide rods into the parallel bores and lateral shifting thereof through the power tool's integral base plate whereupon the assembled power tool and the auxiliary base plate member may be inverted and inserted into the first through opening in the work bench top for support by the inwardly extending flange; with the work bench top, and the inwardly facing surfaces of the auxiliary base plate members and the power tool's integral base plate lying in a common plane defining a work surface.
