Feb 8, 2013 updates: I discovered the versatility of the Nova Live Center system. The cone that comes with the system is perfect for supporting the ball end while finishing the handle. I love the versatility of this high quality live center system. It has three bearings compared to one for most OEM live centers and two in the Oneway or Powermatic live center.
Here is a shop made captive ring tool I made from an inexpensive HSS tool bit blank from Enco. It is 8" long and 1/4" in diameter and costs less than $3. You can also use it to make a round skew, Drozda Vortex tool, pyramid tool and more. Order more than one blank! Flatten both sides and then cut the "cat's claw" with the corner of the grinding wheel or a rotary Dremel style tool with a stone bit.
