This report details the engineering design, development and application of equipment to produce step threads (constant lead thread on two or more diameters) on the breechblock of cannon. The equipment uses a blade type tool with the part being threaded through shaper type cuts until finish size is reached. The use of this equipment will reduce the floor to floor time from 7.5 hours to 2.0 hours while producing better thread finishes and more accurate dimensional sizes. (Se)
