ABSTRACT:
A drill guide apparatus and method for its use is disclosed. The apparatus includes, in one embodiment, first and second vise jaws for clamping a workpiece. The vise jaws are adapted to receive a drill guide holder which includes first and second elongate members which properly position the drill guide itself. One end of each of the elongate members is attached to each of the vise jaws by pins which pass through the member and into a hole in the top of the vise jaw. The opposite ends of the elongate members are positioned above the space between the vise jaws and are hinged together by a ferrule which passes through the two members. A cylndrical drill guide which has a hole therethrough adapted in size to accept a particular size drill bit is fitted into the ferrule. The drill guide is thus located in a central position between the vise jaws above the workpiece which is clamped by the jaws. As the vise jaws are opened or closed to accommodate different size workpieces, the drill guide positioned at the vertex of the hinged elongate members remains centered above the space between the jaws.
