  • Patent number: 4600044
    Abstract: A method and apparatus for joining fittings, particularly wooden stair rail fittings. The apparatus includes a mitre jig and a double slot jig. The mitre jig has a base with a curved bed for supporting the fitting to be cut. A wall is used with the base that has on it a scale for indicating the angle of incline of the stair being worked with. A recess in the wall accommodates a saw and a slot in the wall receives the saw blade. The fitting is placed on the base with its seam aligned with the particular indication for the stair's angle of incline. A saw is then used to cut the fitting. The double slot jig is used to cut slots into the ends of fittings for joining them. The double slot jig has a base, a tray, a double-bladed cutting apparatus, and a frame. The tray supports the fitting to be cut and is movable on the base. Appropriate stops are used to correctly position the fitting on the base and to limit the movement of the tray on the base. A drill with double circular blades can be used.
