Model G0824 (Mfd. Since 12/16)
Installing Tooling
Using Quill
1. Rotate quill lock lever counterclockwise to
loosen quill.
2.
Turn quill handwheel clockwise to move quill
toward spindle or counterclockwise to move it
away from spindle.
3.
Rotate quill lock lever clockwise to secure
quill.
This tailstock uses a quill with an MT#3 taper that
has
a lock slot in the back of the bore that accept
s
tang
arbors and drill bits (see the Figures

To install and use 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.
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.
