I used to cut barrel threads on a Clausing Colchester 14X40 that had a high
speed threading attachment. It disengaged automaticly when the carraige hit
a preset stop. 16 tpi at 600 rpm. It was scary when I first used it thinking
I'm gonna hit the shoulder, but it never did. I wish I had that attachment
on my 5914. Anybody ever seen one one?

I like to cut a "runout groove" where the threaded secton
meets.......
I agree with Randy. Fainthearted? No. But you really, really need to
pay attention when you get close to this end of your threading.
