A 5/8" diameter mandrel with a #1 or #2 Morse taper specifically for using the Beall wood-buffing system or the Beall bowl sets on a lathe. The mandrel is used in combination with a quick-change adapter, which is included with the wood-buffing system. Drilled and tapped for a 1/4-20 restraining rod/bolt (not included) to draw the taper securely into your spindle.
