One might think it is impossible to do with repeatability and
assurance.
So - I am curious - what is it that aerospace requires that is 50
"millions"? I worked in that space for a while and I never saw any
tolerances like that - but that does not say much. I believe that
even the space shuttle does not demand tolerances that close - but I
really do not know.

What is the tolerance for hydraulic spool valves?
