Tailstock
The tailstock (see Figure 26) can be used to
support workpieces with the use of centers. It can
also be used to drill or bore holes, or cut shallow
tapers by using the offset set screws.

Positioning Tailstock
1. Loosen the tailstock lock nut.
2. Slide the tailstock by hand to the desired
position.
3. Re-tighten the tailstock lock nut.
Using Quill
1. Rotate the quill lock counterclockwise to
allow for quill adjustment.
2. Turn the quill ball handle clockwise to
move the quill toward the workpiece or
counterclockwise to move the it away from
the workpiece.
3. Re-tighten the quill lock to secure the quill.
Installing Tooling
This tailstock quill accepts tooling arbors and
drill bits with an MT#2 taper (see Figures 27 for
examples).
If the arbor has an open hole in the end, a screw
can be threaded into the end of it to provide a
solid surface for the quill pin to push against
when the quill is retracted for tool removal.
To install tooling in the tailstock:
1. With the tailstock locked in place, unlock the
quill, then use the quill ball handle to extend
the quill approximately 1 ⁄
2
".
2. Thoroughly clean and dry the tapered
mating surfaces of the quill and the center,
making sure that no lint or oil remains on
the tapers.
Note: This helps ensure that the tool seats
properly and has minimal runout.
3. With a firm and quick motion, insert the tool
into the quill. Check to see if it is properly
seated by attempting to twist it by hand—it
should not twist.
4. Unlock the tailstock and move it until the tip
of the tool is close to, but not touching, the
workpiece, then re-lock the tailstock.
Note: The tool may seat further when it is
pushed against the workpiece.
