Taper Turning by Setting top Slide
By angle the top slide, tapers may be turned manually with the
Top slide ( Fig. 18 ).
Rotate the top slide to the required angle. A graduated scale
permits accurate adjustment of the top slide. The cross feed is
performed with the cross slide. This method can only be used for
short tapers.

Threads Cutting
Set the machine up to the desired thread pitch (according to the
Thread chart Fig. 7). Start the machine and engage the half nut.
When the tool reaches the part, it will cut the initial threading
pass. When the tool reaches the end of cut, stop the machine by
turning the motor off and at the same time back the tool out of
the part so that it clears the thread. Do not disengage the half
nut lever. Reverse the motor direction to allow the cutting tool
to traverse back to the starting point. Repeat these steps until
you have obtained the desired results.
