3. Retighten the clamping hex bolts underneath
the tailstock to secure the offset.
2. Rotate the adjustment set screws in opposite
directions for the desired offset
(see the illus-
tration below).
To offset the tailstock:
1.
Loosen the hex bolts underneath both ends
of the tailstock to release the clamping pres-
sure between the top and bottom castings
shown in the Figure below.
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.

Figure 47. Turning a dead center.
To align the tailstock to the spindle center-
line:
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 with this procedure
(refer to the Leveling & Mounting
in this manual).
Center drill both ends of one piece of round
stock, then set it aside for use in Step 5.
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.
