He did seem to enjoy it. I'm sure his mother would not approve.
 
I have a metric lead screw hence no thread dial. I always have to back out and back up. Half-nut stays engaged till I'm done. My threads are crappy if I try to use the compound method, so I just go straight in with the cross-feed and pretty threads. Not sure why the 29.5 deg. thing does not work for me but until I have to thread something hard I won't worry about it.
 
I watched this thread from the beginning. Even offered up a post to help out. This has been quite a journey and the result was exceptional. Another classic example why this is the best machinist forum on the net. People coming together to help out a fellow machinist make his machine more useful. What more can you ask for.

I will start a new thread for you for figuring out the gear size for your thread dial.
