You know, I was thinking about that after I posted it. I should just pop the 201HC into the treadle and see how that goes. I really think this is where the "never turn the hand wheel backwards" part comes from. It doesn't hurt a machine, just messes the thread up on some machines but of course, like so many other things it's reached mythology status.
