ABSTRACT:
The invention relates to a spacer for a rotary peening apparatus having a hub and a plurality of peening flaps that are spaced about and retained by the generally cylindrical peripheral surface of the hub. Each peening flap includes several peening rivets attached to a distal end of the peening flap. The spacer of the present invention positions the peening flaps at at least two locations inward of one of the hub ends of the hub, which enables the rotary peening apparatus to impart a uniform surface finish to a surface.
