The amazing Bushmaster automatically inserts bushing cloth to the correct depth in the key mortise. This finely crafted brass tool allows you to install new bushings quickly and efficiently, eliminating guesswork. With glue in several mortises, use Bushmaster to push the cloth into a mortise until the Bushmaster bottoms out. Push the spring-loaded handle to eject a double-edged blade. The result: each side of the mortise receives exactly the same amount of bushing cloth; you save lots of time. A factory method, no wasted motion. Extensive directions and helpful hints included to assist you in doing a very professional bushing job. Finely machined from solid brass and aluminum. Replacement blades available.
