    Here is an article about it. The long arm fastened to the bed works the same way as an adjustable stop on a drill press. It has free movement of the tool till it hits the end stop.

    Ah. In the front page photo posted it's cutting an external thread. I was trying to figure out how something angled that way would stop cutting internally.
    Very complex mechanically.
    Thanks for passing that on.
