Live Centers
a live center (not included) has bearings that allow the center tip and the workpiece to rotate together; it can be installed in the tailstock quill for higher speeds.
Mounting Dead Center in Spindle
1.disCoNNECt lathE FroM poWEr!
2.thoroughly clean and dry all threads and mating surfaces of the spindle bore and the center, making sure that no lint or oil remains on these surfaces.
Note: This will prevent the tapered surfaces from seizing due to operational pressures, which could make it very difficult to remove the center.
3.Mount the chuck, faceplate, or drive plate onto the spindle, whichever is correct for your operation.
4.insert the center into the spindle bore through the chuck, faceplate, or drive plate.
the figure below shows an example photo of a dead center installed in the spindle, using a lathe dog and faceplate for turning between centers.

To avoid premature wear of the dead center or damage to the workpiece, use low spindle speeds and keep the tip of the dead center mounted in the tailstock well lubricated.
To mount a center in the tailstock:
1.disCoNNECt lathE FroM poWEr!
2.thoroughly clean and dry the tapered mating surfaces of the tailstock quill bore and the center, making sure that no lint or oil remains on the tapers.
