An improved method of making a collector ring enhances the cyclic engagement and disengagement of a spring clutch of the type having an annular spring compressed between a clutch cover and plurality of externally located release levers. The preferred method is applicable to a collector ring which defines a radially extending annular base member having an integral axially extending rim on its outer perimeter. The rim abuts and encircles the outer circumference of the annular spring, while the base member is positioned interjacent the spring and levers for transfering reaction loads therebetween. A preferred method of making the ring comprises the steps of (a) forming a body defined by a radially extending planar portion having an integral, axially extending, circular perimeter; (b) forming an annular reduced shear portion on the body radially inwardly of the latter perimeter to define an outer annular ring thereon, wherein the ring is integrally joined to the body at the reduced shear portion, (c) heat treating the body, and (d) detaching the outer ring from the body at the reduced annulus. The detached ring defines the improved collector ring.
