A bit more progress. The draw bar is 3/4" welded steel tube, with a threaded plug pressed in the end, and threaded into the Morse Taper 3 sleeve....
The Morse Taper 3 sleeve was machined and marked/indexed to the spindle so that I can put it in at the same position. As it was bored in place, do this will keep the runout of the armature down to .0005" range which is where it is now....
Coming along nicely....
