Are you tired of bending your Mandrel and ruining the point on your live center? If so, then this fail-safe live center accessory is for you. Mandrels usually bend when you tighten the tailstock center point into the end indentation of your mandrel. This system solves that problem because your mandrel shaft goes through the hollow live center. Your bushings press against the center with zero pressure on the mandrel shaft. The tube and bushing assembly tightens up by turning your tailstock quill adjustment wheel. Great for beginners and students.
