Cutting an Internal Thread on the Atlas Lathe

[TomG]

After making "Thread cutting on the Lathe, Part Four", there was some whining about how anyone can cut nice threads on a Hardinge, and what about us Atlas guys? Well, as I said in the video, the process of cutting a thread is pretty much the same on any lathe, and to prove the point, I packed up the camera and headed over to my Dad's house to cut a mating 1-12UNF 3B thread on his Atlas lathe. I have to say that I was sweating a bit since I haven't used an Atlas in over 30 years, and never cut threads with change gears, but it turned out alright and I actually learned a few things. Like I don't want an Atlas in my shop.

Anyway, here is the result, with the second part to follow shortly.
