ABSTRACT:
The disclosed shank slot dial has two equi-diameter cylindrical members each having a like plurality of axial notches equally spaced around the circumferential surface of the member. Mating helical thread means formed on the members concentrically of the notched surfaces allow for relative rotation of the members, which adjustably varies the axial spacing between the surfaces for proper support of the shanks to be fixtured in the dial. Keying means in the form of an axial grove on one member and a radially movable set screw on the other member nonrotatably hold the members at selected axial spacings and with the notches longitudinally aligned. The shank components supported in the dial thereby are abutted only at their end sections in corresponding aligned pairs of notches and bridge across at their intermediate sections the spacing between the notched surfaces.
