Last fall I picked up a Cincinnati 2ML from a local university. It appears to be in good shape, most everything feels tight, and moves as I believe it should but I have a question before putting power to it, that I'm hoping the forum here can help me with. The main spindle, regardless of which gear it's in, or rotational direction or any other settings, it is free to spin, with no gear engagement. Is this normal? I would have thought that when the clutch was engaged, it would cause the spindle to turn the gears. I've tried manually spinning the drive motor to make sure that the gear train is good all the way to the spindle, but I've never been able to get the spindle to turn by this method. Is there something that I'm missing?
