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 25 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 counter-weights to balance
the assembly and use a dial indicator to make
sure that the workpiece is properly positioned
for your operation.

The tailstock (see Figure 26) is typically used to
support long workpieces by means of a live or
dead center (refer to Centers on Page 33). 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.
