OPERATION
Adjustable Feed Stop
The adjustable feed stop system will only stop
carriage movement if 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 operations, make
sure to loosen the feed stop collar so it slides
freely on the feed rod and will not interfere
with carriage travel.
This machine features an adjustable stop system
that can be used to stop the carriage at a pre-set
location when it is being driven by the feed rod.
This system consists of an adjustable collar on
the feed rod, a stop plate on the apron, and the
feed rod clutch (see Figure 69). The collar can
be secured anywhere along the feed rod. When
the stop plate contacts the collar, the feed rod
clutch disengages the feed rod and stops carriage
movement.
Note: This system only works when the carriage
is engaged with the feed rod—it cannot be used
to stop the carriage if it is engaged with the
leadscrew.

To set the micrometer stop:
1. DISCONNECT LATHE FROM POWER!
2. Loosen the cap screws shown in Figure 70,
then use the carriage handwheel to position
the carriage and cutting tool at the desired
stopping point.
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 chuck, jaws, or other components.
The micrometer stop used to limit carriage travel
for production runs or make final adjustments
to the carriage position. To ensure accuracy with
repeatable operations, the operator must ensure
that carriage contact is done in a soft and careful
manner. The micrometer stop should never be
used as a stop for power feeding operations.
The micrometer stop is not designed to stop
carriage movement when the leadscrew or
feed rod is engaged—doing so may damage
the micrometer stop or lathe components.
