Abstract
A variety of precision tools and accessories, and precision tool sets, for selective use either individually or in relatively interconnected relation for securing a workpiece in a particular orientation for work to be performed thereon. In the precision tool sets, each of the separate precision tools is provided with a plurality of mating apertures having a pattern which matches the patterns of other mating apertures of other ones of the precision tools, thus permitting selective and interchangeable interconnection of desired ones of the precision tools by suitable fasteners received through the mating apertures. One of the basic component precision tools of such a set comprises a sine plate which may preferably include a locking strap particularly configured to avoid interference with the upper planar working surface of the sine plate. Another basic component precision tool of the set comprises a magnetic chuck adapted either for individual use or for interconnection to the sine plate or other precision tools, and provided with a bottom plate having mating apertures disposed therein. Also provided is a precision tool kit wherein at least one of the precision surfaces of the compon…
