PR, Here is another image, perhaps the
change in size of the shaft is interfering with the tightening of
the nut and the outer stack of gears and spacers and aligning
shaft keys?
Again, Good Luck!

1/100mm is about .0003". Over what distance are you
trying to maintain that? Just curious as it shouldn't be a
problem on shorter lengths with everything properly adjusted
and aligned especially the saddle and headstock. I may have
missed where you said but if you're saddle travel isn't
perfect you're not gonna get .0003" unless you work only in
the "good" area of travel. Then the headstock has to be done
but anyway...

The inner race of the inner bearing can be an
interference fit on the spindle albeit very slight. Like tap
it with a wooden hammer handle only to fully seat it.?

?The inner race of the outer bearing should be a very
snug slip fit on the spindle. That race has to be able to
slide just like on a vehicle. ?It's fairly time consuming
process. ?Sounds like your spindle wasn't properly fit for
the bearing. If it was the race would move so you can set
it. I think you're first step is going to be to rectify that
and from there you're going to be set on that part.
