The Huth Ben Pearson Dead Stop Swaging Positioning System makes swaging (expanding, reducing, shaping) repeated tube and pipe-based parts quicker and easier. To use, attach the system to the back end of the swage box on a Huth pipe bender or 1673 expander-reducer machine. Then, set the stop location with the positioning pins and use the adjustable screw thread to fine-tune their setup. It reduces collet marks. The Dead Stop can be purchased with a Huth pipe bender or model 1673 expander reducer, or purchased alone.
