Abstract: An apparatus for supporting and guiding a router in cutting work-pieces to form an interlocking joint comprises a base support member to which two work-pieces are mounted, at least one being in a horizontal plane. A template is also mounted to the base support member above the horizontal positioned work piece. The template is adjustably connectable to the base support member and vertical and horizontal work-piece clamping assemblies are provided with a movable clamping device so that clamping pressure is applied adjacent to each work-piece in holding the work-pieces on the base support member for cutting.

Abstract: A ratchet handle includes a composite ratchet gear having a passageway therethrough and an inner sleeve within an enlarged portion of the passageway. The passageway has a smaller flat-sided portion forming a tool holding aperture aligned with an internal tool holding aperture in the inner sleeve. A tool holding washer is captured between the inner sleeve and the ratchet gear. Improved positive control apparatus includes a slider control device moving yieldable detents formed by yieldable convoluted plate and projections on a stationary cover plate.
