Removing Tooling
1. Use shop rag to hold tool.
2.
Rotate quill handwheel counterclockwise to
fully retract quill into tailstock until tool is
forced out of quill.
Offsetting Tailstock
The tailstock quill can be offset from the spindle
centerline for turning tapers. Offsetting the quill
toward the front of the lathe results in a taper at
the tailstock end. Conversely, offsetting the quill
toward the back of the lathe results in a taper at
the spindle end.
Note: The marks on the offset indicator are arbi-
trary. For a precise offset, use a dial indicator to
check quill movement while adjusting the screws.

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.

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
2. Center drill both ends of a piece of round
stock, then set it aside for use in Step 5.
