This lathe can cut inch and metric threads. It is equipped

with a thread dial that lets you know where to re-engage

the half nut when cutting most inch threads. The thread

dial makes sure the cutting tool falls back into the same

groove that has been just cut.

To setup for threading, do these steps:

1. DISCONNECT THE LATHE FROM POWER!

2. Install the appropriate change gears to achieve the

thread pitch needed. For example, the chart below

shows that to get 40 threads per inch, you must

move the gearbox lever to position "+ (Figure 37),

and install the gears stamped "*' and "-'" in the

"X and "Y positions shown in Figure 38.

Note: B\\gk_\^\XiYXZbcXj_jc`^_kcpcffj\ at

0.003" to 0.008".

3. Set your cutting depth to a few thousandths of an

inch, engage the half nut lever, and engage the

threading dial (Figure 39).

4. Turn the lathe on, let it thread, and turn the lathe

off before the tool or apron crashes. Finish the

threading pass by manual rotation of the chuck, and

then disengage the half nut lever.

5. Return the apron, position the tool to make second

the pass, and engage the half nut where the dial

indicated by the thread dial chart on the apron.

=FID<KI@:K?I<8;@E>, keep the half nut engaged

during the entire threading process. When the tool

reaches the end of the first threading pass, turn the

motor F== and back the tool out of the thread. Reverse

the motor direction to move the cutting tool back to

the thread beginning. Repeat these steps and DO NOT

disengage the half nut until you have completed your

thread.
