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 shaft. This system solves that problem because your mandrel shaft goes through the hollow live center, and rides on a presision bearing. Your bushings sit against the center with zero pressure on the mandrel shaft. The pen tube and bushing assembly tightens up by turning your tailstock quill adjustment wheel. Great for beginners and students. Unique design to support the end of your mandrel. Provides no pressure on the mandrel thus eliminating any bending and vibration. There is no longer a need for spacer bushings. The live center is now obsolete. Will work with all mandrels with a diameter of 0.245-Inch or less.
