I couldn't bring myself to buy one at the price, so I figured since I have a lathe and generally know what I'm doing with metal I'd make one. The keeper setup to hold the tube in place seemed a bit chintzy to me, so I replaced it with a setup similar to what you see in a pin vise. While it works nicely, I'm wondering if there are any other improvements to be made.
Any thoughts?
