Somebody is gonna hate me. 
Need to thread 1.125-40 for a distance of .187. Power is out of the question. Sooo -- I made a Spindle Handwheel to turn the spindle while single pointing the thread. It has a mandrel that fits into the spindle at the back. A tapered draw bar opens the mandrel when in position to lock it into place. I still need to split the mandrel in four places to get the spring action needed.
