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.

Micrometer Stop

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.
