Changing Tapping and Power Feed Speed (Manual Lathe)

Description
The Logan manual lathes can be used to cut external threads, and they are capable of producing better results than cutting threads by hand using a die.

Part Design
The section of the part to be threaded should match the nominal diameter of the threads to be added. For example, a rod to be fitted with 1/4"-20 threads should be a 1/4" rod. Also, the end of the rod should have a chamfer at least as deep as the threads to be cut. This will make the threads cut cleaner. Finally, a thread relief section should be added behind the threads if possible.
