3.
Align the tool bit to the sides of the V-shaped cutout in the side of the
center gage.
4.
Secure the tool bit in position.
5.
Advance the tool bit until the point just makes contact with the workpiece.
6.
Zero the cross slide dial. Hold the cross slide feed handle and rotate the
graduated dial.
Threading Process
It takes several passes to cut a thread to full depth. You must follow the
correct procedure during each pass to ensure the thread is cut correctly.
Use the power feed forward/neutral/reverse lever to engage the lead screw
drive. The carriage should move from right to left (toward the head stock) to
cut right-hand threads, or from left to right (away from the head stock) to cut
left-hand threads.
For each pass in cutting threads:
1.
Move the carriage to the beginning of the cut.
2.
Advance the cross slide to the initial position. For the first pass, you are
already there. For additional passes, advance it 2 complete turns to the 0
mark.
3.
Advance the compound rest to move the tool bit into the work. For the first
pass, this should be only 0.001". For additional passes, it should be 0.005 to
0.010".
4.
Start the lathe. Run it at the lowest speed that develops sufficient torque
to make the cut.
5.
When the threading dial reaches an appropriate mark, engage the half nuts.
Note that you must be right on the mark. The half nuts will also engage
halfway between each mark, but this will ruin your thread.
6.
When the tool reaches the end of the thread, disengage the half nuts.
7.
Back off the cross slide exactly 2 turns.
