To mount a non-concentric workpiece to the faceplate:
1.DISCONNECT LATHE FROM POWER!
2.Protect the bedway with a piece of plywood.
3.With help from another person or a holding device to support the workpiece, position it onto the faceplate and clamp it in place with a minimum of three independent clamping devices (see Figure 39 for an example).
Be sure to take into account the rotational and cutting forces that will be applied to the workpiece when clamping it to the faceplate. If necessary, use

Tailstock
The tailstock (see Figure 40) is typically used to support long workpieces by means of a live or dead center (refer to Centers on Page 46). It can also be used to hold a drill or chuck to bore holes in the center of a part. Custom arbors and tapers can also be cut on your lathe by using the offset tailstock adjustment.

3.Push the tailstock lock lever forward (toward the spindle) to lock the tailstock against the bedway.
Using Quill
1.Move the quill lock lever toward the spindle to unlock the quill.
2.Turn the tailstock handwheel clockwise to move the quill toward the spindle or counterclockwise to move it away from it.
3.Move the lock lever away from the spindle to secure the quill in place.
