Abstract
A complete pen mandrel turning assembly that may allow for simple, accurate, and repeatable centering of a pen mandrel shaft. The presently disclosed system may further include a tail stock assembly that is adjustable to allow the tail stock to be positioned right next to the pen blank to eliminate any chance of runout and other associated problems. Further, the present disclosure may provide a series of precision bushings for use with the pen turning assembly to securely hold a pen blank in the turning assembly while providing an accurate and precise turning reference for the pen turner.
