The following subsections describe how to use
the threading controls and charts to set up the
lathe for a threading operation. If you are unfamil-
iar with the process of cutting threads on a lathe,
we strongly recommend that you read books,
review industry trade magazines, or get formal
training before attempting any threading projects.
Headstock Threading Controls
The threading charts on the headstock face dis-
play the settings for metric and inch threading.
Using the controls on the lathe, complete the fol-
lowing examples to better understand how to set
up the lathe for the desired threading operation.
Threading
4. Open the change gear cover, loosen the lash
adjuster (Figure 61 on Page 45) and swing
the change gear assembly out of the way.
5. Remove the E-clips and cap screw from the
change gears.
6. Lubricate the change gears (refer to Page 55
for detailed instructions) and swap them out
in the order shown on the chart in Figure 62,
then secure the change gears with the E-clips
and cap screw.
Note: All change gears are stamped with the
number of teeth they have.
7. Move the lash adjuster so the gear backlash
is between 0.003" to 0.008", tighten the lash
adjuster cap screw, and close the cover.
8. Loosen the carriage lock (see Figure 60 on
Page 45).
The lathe is now set up to cut 64 TPI threads.
When threading keep your hand on the half-
nut lever ready to disengage the half nut to
avoid potential carriage/chuck crash.
To set the lathe to cut 64 TPI threads:
1. DISCONNECT LATHE FROM POWER!
2. Turn the feed dials to the numeral and letter
indicated by the chart in Figure 62.
Note: You may have to rock the chuck by
hand to mesh the gearbox gears.
3. Gather the required change gears based
upon the chart.
