In todays demonstration I describe how to cut a metric pitch thread up to a shoulder on an old Atlas lathe with no reverse spindle and an 8 teeth per inch lead screw. Included is how to select and set the manual change gears how to maintain the thread position even when disconnecting the half nuts using a threading dial.

Here is a link to the parts manual for this lathe. The full thread cutting chart is at the end. This is also a great site. Lots of useful stuff here.
