The following subsections describe how to use
the threading charts and controls 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 inch and metric threading.
Using the controls on the lathe, follow the exam-
ple below to understand how to set up the lathe
for the desired threading operation.
