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.
=FID<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.
