Thread Dial (Non-Metric Threads)
Items Needed
Hex Wrench 5mm .............................................. 1
The numbers on the thread dial are used with the
thread dial chart to show when to engage the half
nut during inch threading. Loosen the cap screw
on the thread dial (see Figure 79), pivot the gear
teeth so they mesh with the leadscrew threads,
then re-tighten the cap screw.
Note: The thread dial is not used for metric
threading. You must leave the half nut engaged
from the beginning until the turning is complete for
this type of operation.

When threading, we recommend using the
slowest speed possible and avoiding deep
cuts, so you are able to disengage the half
nut when required and prevent an apron
crash!
When the first thread cutting pass is complete,
the operator disengages the carriage from the
leadscrew using the half nut lever. The operator
returns the carriage for the next pass and re-
engages the half nut using the same thread dial
setting to resume the cut in the previous pass.
