ABSTRACT:
A clamping means for clamping a work piece with non-planar surfaces in a vise. The clamping means comprises two support blocks and three or four clamping members. Each clamping member has a stem portion and a collinear work piece engagement portion. The support blocks position the stem portions to define a plane tangent to the stem portions that is spaced from the support block and parallel to it. Jaws on the vise contact the stem portions directly on this plane, and not the support block. The tops of the support constitute a horizontal support for the work piece as the jaws are tightened to close the work piece engagement portions into clamping engagement at locations spaced about the periphery of the work piece.
