However, other tooling without tangs, such as
the four remaining tools shown previously, can
still be used if the potential load will not exceed
the strength of the tapered fit. For example, this
includes smaller drill chucks, drill bits, and centers.
Note: If the tooling has an open hole in the end
but is too short to be exposed in the drift slot for
removal, then a screw can be threaded into the
end of the tool to provide a solid surface for the
quill pin to push against when the quill is retracted
for tool removal. Otherwise, removal of such tool-
ing may be difficult.
To install tooling in tailstock:
1.
With tailstock locked in place, unlock quill,
then use handwheel to extend it approxi-
mately 1".
2.
Thoroughly clean and dry tapered mating
surfaces of quill and center, making sure that
no lint or oil remain on tapers.
Note: If tapered tool shaft has a tang, align
it with slot in back of quill before seating it.
3.
With a firm and quick motion, insert tool into
quill. Check to see if it is firmly seated by
attempting to twist it—a firmly seated tool will
not twist.
4.
Unlock tailstock and move it until tip of tool
is close to, but not touching workpiece, then
relock tailstock.
5.
Start spindle rotation, unlock quill lock lever,
then turn quill handwheel clockwise to feed
tool into workpiece.

Removing Tooling
1.
Use shop rag to hold tool.
2.
Rotate quill handwheel counterclockwise until
tool is forced out of quill.
— If tool does not come loose by retracting
quill, extend quill and use drift key in slot
shown in Figure below to remove tool.

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 (see
Figure 42 on the next page) are arbitrary. For a
precise offset, use a dial indicator to check quill
movement while adjusting the screws.
