Aligning Tailstock to Spindle
Centerline
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

Round Stock 2" x 6" .......................................... 2
Precision Level .................................................. 1
Lathe Dog .......................................................... 1
To align tailstock to spindle centerline:
1.
Use precision level to make sure bedway is
level from side to side and from front to back.
— If bedway is not level, correct this condition
before continuing with this procedure (refer
to Leveling section in this manual).
2.
Center drill both ends of a piece of round
stock, then set it aside for use in Step 5.
3.
Use another piece of round stock to make a
dead center. Turn it to a 60° point, as illus-
trated below.

Note: As long as this dead center remains
unmoved in the chuck, its point will remain
true to the spindle centerline. However, if the
center is removed and later returned to the
chuck, the point must be re-turned to once
again be true with the spindle centerline.
4.
Install center in tailstock.
5.
Attach lathe dog to test stock from Step 2,
then mount it between centers, as shown
below.

between the centers.
6.
Turn 0.010" off stock diameter.
7.
Mount test or dial indicator so that plunger is
on tailstock quill.
Note: If necessary in the following step, refer
to the Offsetting Tailstock subsection for
detailed instructions.
