Adjustable Feed

Stop

Use the adjustable feed stop collar (shown in Figure 65) to set the location where the carriage should disengage from power feed.

When the apron stop plate contacts the stop col- lar during an operation that uses the feed rod, the clutch disengages the carriage from the feed rod and movement stops.

Figure 65. Adjustable feed rod stop.

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.

Use the carriage stop as a guide to help judge when to stop carriage movement.

The carriage stop on this lathe will NOT automatically stop the carriage during 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.
