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.

A central axis adjustment structure of a tailstock of a woodworking lathe is disclosed. The tailstock has a circular hole therein, a front opening and a rear opening at front and rear ends of the tailstock. An end surface of the front opening has at least one screw hole. A guide rod is disposed in the circular hole, and has a rear end extending out of the rear opening. A collar is fitted onto an axial connecting shaft that is inserted in the circular hole. The guide rod is insertedly connected to a rear end of the axial connecting shaft. The collar has at least one perforation corresponding to the screw hole. At least one bolt is inserted through the perforation and screwed to the screw hole so that the collar is locked to the front end of the tailstock. A first annular gap is defined between the guide rod and the rear opening of the tailstock. A second annular gap is defined between the axial connecting shaft and the front opening of the tailstock. A third annular gap is defined between the bolt and the perforation of the collar.
