Lets see, while threading with half nut the dial stops and half nut disengauged it
revolves. If it revolves there is nothing wrong with it. This has been asked before
simply in short say if you are in a bus in front and bus travels walking speed and
you walk to the rear exactly the speed of the bus look out window and you are stopped
you have not moved at all so each other canceled movement. The bus-carriage-stops
you-leadscrew-are still walking and around she goes. best I can do on that one. My
dial I made out of an exhaust valve I marked the lines and numbers but I turned a
ring with a witness mark >then engauge 1/2 nut cut power then turn the ring to what
ever no. or line I want then try it under power suppose a big washer will do.
