Chart
To use the thread chart, find the TPI that you want
to cut and reference the "Scale" number(s) next to
it. The scale number(s) indicate when to engage
the half nut when cutting that TPI.
For Example: If you are cutting 13 TPI threads,
the chart shows "1, 3, 5, 7" next to the 13 (see the
shaded boxes in Figure 81).

cut any thread by starting and stopping on the "1"
on the thread dial.
