ABSTRACT:
A workpiece support for use in setting up a workpiece in a vise on a machine tool. Blocks are each attachable to a jaw of the machine tool vise and each block defines multiple series of arcuately spaced bores which receive pins which, in turn, support a workpiece angle support member. The member has multiple, workpiece supporting edges inclined to one another. Insertable pins permit re-orienting of the single support member to provide desired inclination of the workpiece. A parallel work support member also has multiple workpiece supporting edges with insertable pins permitting installation of the parallel work support member at different vertical distances from a datum plane such as that containing the lower edge of the vise attached block. Use of vee blocks, both horizontal and upright, permits clamping of round stock for machining. A link between spaced apart blocks of the workpiece holder facilitates machining on a C.N.C. machine.
