Abstract: A universal door hinge template assembly for use with a tool for fabricating a mortise in a door or door jamb for a hinge includes a plurality of template modules including at least two end modules with one or more intermediate modules, where each template module comprises: a base having an aperture defined therein to guide the tool for forming the mortise, the aperture having two pairs of opposing sides; a pair of opposing adjustable hinge templates having a selected shape and selectively positioned at one of the pairs of opposing sides of the aperture; and a plurality of connecting bars of selective length which are selectively fixed between each two adjacent template modules in the assembly.

Abstract: Improvements in a mechanism configured to support a door when work is to be performed using movable clamp halves to clamp and hold a door. A movable ledge receives a door where the weight moves the ledge gravitationally downward to clamp the work piece. A fixed ledge is positioned in the path of movement of the door and the movable ledge to limit the movement and any excessive pressure which otherwise might be exerted on the door by the clamp halves. The clamp is mounted on a base which comprises angled piping to form a two-dimensional support for the clamp and the door. The mechanism includes removable or changeable wheels to transport the mechanism with or without a door. Post and hole braking mechanism is engageable to stop movement of the mechanism. A leg is further extendable to support the mechanism in a three point configuration.
