Abstract:  
This invention relates generally to shot peening of extended work surfaces, and more particularly has to do with the provision of apparatus for controlling shot peening of large work pieces without requiring movement of the work during peening, the shot being at all times confined against escape, and the peening operation being conducted in such a way that shot does not collect on the work piece. The invention finds useful application in those instances where an elongated metal surface must be subjected to shot peening, typical work of this nature comprising aircraft wings, elevators, and the like.
