The
Live Centers
Although the dead center achieves a more accu- rate finished product, it requires low spindle speeds to avoid heat from friction damaging the center of workpiece. The live center has bear- ings that allow the center tip and the workpiece to rotate together, and can be installed in the spindle and the tailstock quill for higher speeds, but with a slight bit of accuracy loss. Refer to the ACCESSORIES section on Page 48 for a live center option from Grizzly.
Using Dead Center in Spindle
When mounting the workpiece between cen- ters, install a lathe dog on the spindle end of the workpiece and insert the tail of the dog into the chuck or faceplate to keep the workpiece and center rotating together during operation (see Figure 36 for an example).

When using a center in the spindle to mount a workpiece, the other end of the workpiece MUST be supported by a center installed in the tailstock quill to safely hold the workpiece in place during operation. Otherwise, the workpiece can be ejected from the lathe when the spindle rotates and could cause serious personal injury or property dam- age.
