Abstract
A clutch race is formed from multiple layers of stampings which are joined together. Each of the stampings has a plurality of semi-perfs which include a protrusion on one side and pocket on the opposing side. The protrusions of one layer are interconnected with the pockets of an adjacent layer. The stampings forming the individual layers may either define a complete circle or an arcuate segment of a circle, which arcuate segments, when assembled, form a circular layer to be joined with adjacent layers.
