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.

To set the micrometer stop:
1.
DISCONNECT LATHE FROM POWER!
2. Loosen the cap screws shown in Figure 63,
then use the carriage handwheel to position
the carriage at the desired stopping point.

Adjustable Feed Stop
Use the adjustable feed stop collar (shown in
Figure 62) to set the location where the carriage
should disengage from power feed.
When the apron stop plate contacts the stop
collar during an operation that uses the feed rod,
the clutch disengages the carriage from the feed
rod and movement stops.

The adjustable feed stop system is designed
to stop longitudinal carriage movement at the
desired location ONLY when the carriage is
engaged with the feed rod.
When the carriage is engaged with the
leadscrew for threading operations, the
adjustable feed stop system WILL NOT stop
carriage movement—you must use the half
nut lever instead. Otherwise, the carriage can
crash into the chuck, or if it contacts the stop,
the leadscrew shear pin will break.
Before doing any threading operation, make
sure to loosen the feed stop collar so it slides
freely on the feed rod and will not interfere
with carriage travel.
The micrometer stop allows you to stop the
carriage at the same position for repeat cuts,
such as when turning up to a shoulder. The
micrometer stop includes a graduated dial that
allows you to precisely position the stop.
The micrometer stop is only designed to be used
when feeding the carriage by hand—it should
not be used as a stop for power feed or threading
operations, because this lathe is not equipped
with an automatic feed clutch.
The carriage stop on this lathe will NOT
automatically stop the carriage during
power feed or threading operations when
the carriage is engaged with the leadscrew!
Failure to heed this notice could result in the
carriage crashing and causing severe machine
or property damage.
