Feb 21, 2022There are two basic types of centers: the live center and the dead center. You fit a live center on the spindle of the headstock. The live center rotates along with the object you are working on. Meanwhile, you fit a dead center on the spindle of the tailstock. This type of center comes in handy when you need to support the other end of an object.
