Aligning Tailstock to Spindle
Centerline
Figure 32. Turning a dead center.
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.
Items Needed

Hex Wrench 4mm .............................................. 1
Round Stock 2" x 6" .......................................... 2
To align the tailstock to the spindle centerline:
1. Center drill both ends of one piece of round
stock, then set it aside for use in
Step 5.
2. Use the other piece of round stock to make
a dead center, and turn it to a 60° point, as
illustrated in the
Figure below.
