Removing Tooling
To remove tooling in tailstock:
1.
Use a shop rag to hold tool.
2.
Rotate tailstock handwheel counterclockwise
until tool is forced out of quill.
Offsetting Tailstock
The tailstock can be offset from the spindle
centerline for turning tapers. Move the tailstock
top casting toward the front of the lathe to
machine a taper at the tailstock end. Conversely,
position the tailstock top casting toward the back
of the lathe to machine a taper at the spindle
end.
Note:
The marks on the offset indicator are
arbitrary. For a precise offset, use a dial
indicator to check quill movement while
adjusting the screws.

To install tooling in tailstock:
1.
With tailstock locked in place, unlock
quill, then use handwheel to extend it
approximately 1".
2.
Thoroughly clean and dry tapered mating
surfaces of quill and center, making sure
that no lint or oil remain on tapers.
Note:
This will ensure that tool will seat
properly and reduce runout.
3.
With a firm, 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, then
turn quill handwheel clockwise to feed tool
into workpiece.
To offset tailstock:
1.
Loosen tailstock lock handle to release
clamping pressure between top and bottom
castings (see Figure 38).
2.
Rotate offset adjustment inset screws the
same amount in opposite directions for
desired offset (see illustration in Figure 39).
