Product introduction: High quality replacement parts. This Pen Mandrel Package Includes (5) 7mm Bushings, #1mt Mandrel Saver Tailstock Center, And A #1mt Basic Mandrel (No Threads Or Knurled Nut). 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. No Need For Extra Spacer Bushing As The System Adapts To The Length Of Your Project. .
