Model G4003G (Mfd. Since 1/15)

Threading

The  following  subsections  will  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 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.

To set up for a thread pitch of 13 TPI:

1. DISCONNECT MACHINE FROM POWER!

2. Install end gears as directed on inch thread

chart (see

Figure 70 or the chart on gear-

box).

configuration for 13 TPI.

3. Position gearbox lever pins in gearbox holes

indicated on chart—

B and 7.

— Pull knurled knob out which releases lever

pin from hole.

— Lower lever below gearbox and slide it

directly under desired hole.

— While pulling knurled knob out, raise lever

so that pin is directly over hole, then
release knob to seat pin.

4. Move headstock feed selection to left for

leadscrew rotation.

Apron Threading Controls

The half nut lever engages the carriage with the
leadscrew, which moves the carriage and cutting
tool along the length of the workpiece for thread-
ing operations (see

Figure 71).

IMPORTANT: Make sure the feed selection lever
is in the disengaged (center) position before
attempting to engage the half nut.
