Oh man, I feel your pain and aggravation. Morse taper and draw bolt is good when you want concentricity but a pain when you need length behind chuck. How were you cutting off the excess tube? Parting tool? I find that on my Sherline using their adapter to hold the parting tool cutter upside down on the back side works much better. I would really like to know how they installed those gears on the shafts. Sounded like you had a real good game plan.
