On my web site someone posted this comment concerning lathe centers:

"I may be wrong but I was taught years ago that the difference between
a live center and a dead center was whether there was power to it. A
center is a center. Calling a ball bearing center a "live" center, I
was taught is not correct. The headstock center is a live center, the
tailstock center is a dead center, ball bearings or not. Anybody have
a better take on this?"


A live center, like other living things, moves (in this case, spins).
A dead center, like other dead things, doesn't move.
