longitudinal or cross feed using the feed rod.
3.
set the A–B feed rate lever on the headstock
to A, as indicated on the left (refer to the
Setting Feed Rate controls on page 43 for
detailed instructions).
Note: You may need to rock the spindle,
leadscrew, or feed rod back-and-forth by
hand to get the gears to properly engage.
4.
set the C-F feed rate knob on the gearbox to
D, as indicated on the left.

5.
set the numeric feed rate knob on the gear-
box to 3, as indicated in the top row.
6.
set the quick change gears as indicated in
the left column. Both 40t gears will mesh with
the outer 127t gear (refer to Quick change
Gears on page 44 for detailed instructions).
Example b:
you will be cutting 11 tpi (threads per inch). to set
up your lathe for this task, you will need to:
1.
Find the row that contains the tpi of 11.
2.
set the A–B feed rate lever on the headstock
to A, as indicated on the left.
3.
set the C-F feed rate knob on the gearbox to
c, as indicated on the left.
4.
set the numeric feed rate knob on the gear-
box to 4, as indicated in the top row.
5.
set the quick change gears as indicated in
the left column. the 25t and 50t gears will
mesh with the outer 127t gear.
Note: Refer to Threading on Page 46 for
further instructions on using your lathe to cut
threads.
the bottom chart for metric threading has a slight-
ly different layout than the top chart. For instance,
if you will be cutting a standard metric thread pitch
of 1.25, you would do the following:
1.
set the A–B feed rate lever to A, as indicated
on the left.
2.
set the C–F feed rate knob to E, as indicated
on the left.
3.
set the numeric feed rate knob to 6, as indi-
cated in the upper row.
4.
set the quick change gears as indicated in
the top row for that column.
Note: For metric threading, the top quick
change gear meshes with the outer 127T
gear and the bottom gear meshes with the
inner 120T gear.
