I'm still wondering about even the jet engine parts. Maybe those
parts that are laser cut, but I just cannot imagine machined parts to
those tolerances. I could be wrong as I said in the beginning, but if
I am, I'm suitably impressed.

Not for nothin', but precision bearings are machined to 10 microinches all
the time -- and they're CHEAP!


How many people reading this have ever done any sort
of work close to that precision?

This is what you claimed.
