And here is my version of a threading duplicator which originally was for 3/4-16 threads so i could use my taig chucks on the aa109 lathe

Slow down. I'm having a hard time keeping up with you. puff puff! 

With what you have done with the lathe, I am just about scared to think what you might all come up with if your wife allowed you to buy a mill.

I was told I would want a mill shortly after I got the lathe. I already spent all winter in the basement and got a few for that, so I will wait for a mill

Gotta explain this one to me... how does it work?

Eric, it's a chaser that uses a master thread to move the carriage via a bar behind the bed.  It's become kind of popular with some of the Taig folks.  Unimat used similar in the 50's-60's, and some of the early precision makers in the late 19th and early 20th centuries.  Pretty neat, once you have a number of masters made up.

I think if you search "Keith Brooks threading" you will be able to get a good look at the works.
