Abstract: 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

Abstract: A system of wood combustion employing forced draft is disclosed and comprises a forced draft air and flue arrangement which is utilized with a typical wood heater or wood stove. The forced air and flue arrangement includes a blower, a plenum on which the blower is attached, a panel to which the plenum is attached having air inlets formed therethrough, the air inlets being internal to the plenum, and a flue arrangement attached to the other side of the panel. The flue arrangement includes ducts leading from the air inlets, the ducts having air nozzle slits formed on the other end thereof which are communicable with the internal portions of the wood heater or wood stove. Forced air from the blower enters the combustion chamber through the air nozzle slits. Immediately adjacent to the air nozzle slits and formed as a portion of the flue arrangement is an internal flue outlet for providing an exhaust exit for combustion gases, the flue outlet being communicable with an exhaust pipe.
