ABSTRACT:
A measuring gage for internal and external splines of a workpiece employs a pair of opposed aligned gage pins with hardened balls respectively on their outer ends for registry with internal splines of a workpiece and upon their inner ends for registry with the external splines of a workpiece and with the balls lying in a single plane for operative engagement with the workpiece splines. Longitudinal movement of one of the gage pins is adapted to control axial movement of a plunger upon a dial indicator directly or through a linkage for comparing the dimensions of the workpiece spline with respect to a set master size. In gaging external splines, one of the gage pins forms a part of the dial indicator plunger.
