An excellent aid for pen turners, the Evolution quick change pen centre is intended for use with any of the Axminster pen mandrels. On most pen mandrels the blanks are mounted on the shaft and held in place with a nut at the tailstock end. A live centre is then brought up against the end of the mandrel shaft to support it during turning. The Evolution centre eliminates the need for a nut and there is no compression of the mandrel shaft. The result is that just the blank and any bushings used are now compressed resulting in smoother turning. This also means that spacers are not required as any exposed section of shaft is accommodated within the body of the centre.
