Inch-Thread Dial
The numbers on the thread dial are used with
the thread dial chart on the thread dial body.
The chart indicates when to engage the half nut
for specific inch threading selected on the feed
chart, as shown in Figure 52.
The thread dial gear must be engaged with
the leadscrew for this to function. Loosen the
cap screw on the side of the thread dial (see
Figure 53), pivot the dial gear toward the
leadscrew so that it properly meshes with the
leadscrew threads, then re-tighten the cap screw.

When threading, we recommend using the
slowest speed possible and avoiding deep
cuts, so you can more easily disengage the
half nut to prevent an apron crash!
Attempting to engage the half nut while the
cross slide or carriage is engaged with the
feed rod could cause severe damage to the
lathe. Never attempt to engage the half nut
while the feed control lever is engaged.
For your own safety and protection of property,
consult an electrician if you are unsure about
wiring practices or applicable electrical codes.
