An option for non-Hardinge owners is to set the threading tool up on the back of the part and run the spindle in reverse. Then you can feed the tool from left to right to cut a right hand thread and your reflexes only need to be good enough to keep from running into the tailstock.  Sometimes mine are questionable even at that.

This is the way I always do it. Internal and external. The only time I didn't was the first time I did an ACME thread, and that was only 'cuze I was sure I'd have to redo the tool bit a few times (turned out I only had to once) and wanted it to be convenient.
