Abstract
A method of forming a torsional vibration damping disk, including the steps of: stamping a concave surface at a periphery of a disk; heat treating the stamped disk; placing at least one forming element at least partially in contact with at least a portion of the concave surface; and curling the periphery to partially surround the at least one forming element so that the at least one forming element is removable from the disk. In a second embodiment, the method includes the step of removing the at least one forming element after curling the periphery and includes the step of replacing the at least one forming element with at least one spring element.
