secure the post so the tool faces the tailstock.
2. Install a center in the tailstock, and position
the center tip near the cutting tool tip.
3. Lock the tailstock and quill in place.
4. Adjust the height of the cutting tool so
that the tool tip is aligned vertically and
horizontally with the center tip, as shown in

Micrometer Stop
3. Move the micrometer stop up to the carriage,
use the graduated dial to fine tune the
position, then retighten the cap screws
loosened in Step 2.
4. Verify that tooling will not make contact
with the chuck, jaws, or other components.
The micrometer stop is used to limit carriage
travel for production runs or make final
adjustments to the carriage position.
If power feed is being used and the carriage
clutch is correctly adjusted, the carriage will
disengage from the feed rod when it contacts the
micrometer stop and movement will stop. Refer
to Carriage Feed Clutch Knob on Page 56 for
detailed instructions on adjusting the carriage
clutch.
The micrometer stop is not designed to stop
carriage movement when the leadscrew is
engaged for threading operations—doing so
may damage the micrometer stop or lathe
components.
