Abstract
A method of fabricating a spline drive including the steps of providing an elongated rod of indeterminate length having axially extending splines thereon, cutting a cylindrical member of predetermined length from the elongated rod, turning the cylindrical member at its end to provide splines of reduced height and shoulders at the junctions of the reduced splines and the original splines, broaching a washer to provide an internal surface of complementary mating relationship to the turned end of the cylindrical member, mounting the washer on the turned end with the side of the washer abutting the shoulders, laser-welding the washer to the cylindrical member, and brazing a drum to the washer.
