This Live Center rocks! It has great bearings, great design and will likely outlive its owner. I use it at Wheat State Welding LLC's commercial shop in Derby, Kansas. It is very accurate with very little total stroke displayed. The only thing I would like is a bit on the back so you can remove it from the tailstock by pulling the tailstock all the way back. I think you could cut some threads on the back because there's a hole that's almost a perfect size for a 3/8 thread and put a screw in there like a socket head or maybe just a bolt and this will solve this problem.
