This is an essential adjustment that should be ver-
ified or performed each time the tailstock is used
to turn concentric workpieces between centers
or immediately after offsetting the tailstock when
turning a taper. If the tailstock is not aligned with
the spindle centerline when it is supposed to be,
turning results will be inaccurate along the length
of the workpiece.

To align the tailstock to the spindle centerline:
1. Use the precision level to make sure the
bedway is level from side-to-side and from
front-to-back.
— If the bedway is not level, correct this con-
dition before continuing (refer to Leveling
& Mounting on Page 17).
2. Center drill both ends of one piece of round
stock, then set it aside for use in Step 5.
3. Use the other piece of round stock to make
a dead center, and turn it to a 60° point, as
illustrated in
Figure 31.
