Abstract
Novel modifications to a standard Pro-lok Blue Punch manual punch press machine have been developed which permit the modified machine to accurately and consistently cut Sargent brand L and R series keys to code. Modifications to the same machine are presented such that both Sargent L and R series keys may be cut to code on the same Pro-lok Blue Punch manual punch press machine. Primary features of the modifications are (1) moving the indexing stops from the lower jaw to the upward facing surface of the die and (2) providing two indexing stops on the die such that each stop is laterally positioned on opposite sides of the punch from the other.
