Removing Tooling
1.
Use a shop rag to hold the tool.
2.
Rotate the quill handwheel counterclockwise
until the tool is forced out of the quill.
— If the tool does not come loose by
retracting the quill, extend the quill
and use a drift key in the slot shown in
Figure 41 to remove the tool.

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.

Figure 43. Set screw adjustment in relation to
tailstock movement.
To offset the tailstock:
1.
Loosen the hex bolts underneath both ends
of the tailstock to release the clamping
pressure between the top and bottom
castings (see Figure 42).
2.
Rotate the adjustment set screws in opposite
directions for the desired offset (see the
illustration in Figure 43).
3.
Retighten the clamping hex bolts underneath
the tailstock to secure the offset.
