Thread Cutting - Vevor L2035 Manuel D'instructions

After taper turning, the tailstock should be returned to its original position
according to the zero position on the scale of tail stock. (E, Fig.24)

Thread Cutting

Set the machine up to the desired thread pitch (according to the
threading chart, Fig.20). 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 the 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.
