Well, finally was able to break free some time to work on my scope again, 
and now I'm into the land of stepper motor drives.  I'd like to ask today if

Periodic errors will arise if the stepper shaft and threaded rod drive shaft 
are not aligned perfectly.  That's a problem because even with commercial 
couplers, the threaded rod being undersized for the coupler, will offset to 
the side.  See you can get a machinest to make something up for you where 
the threaded rod screws down into a metal block with the motor shaft coupled 
on the opposite end.
