Also, the reason I want to start using the live center is that it seems that if I am working with a round stock that is out 3 or more inches (not supported on the other end of the chuck) the run out is attrocious. The lathe will not cut a concentric cut on the bar. Does this make sense, the cut material circle will be out of center with the center of the rod, like a cam. Not sure how to correct this other that trying to support the other end with the live center. The chuck I am using is the stock 3-jaw chuck. Will using the live center fix this problem?
Thanks,
Skipper
