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.
