No, but that was never the issuse.
References to astronomy don't make you look good. For various reasons, I have learned to dismiss the astronomy types.
I can. YOu would have to live with my eyes for a day to appreciate that.
For a guy in his woodshop, no.

Really? What types don't you dismiss?
Sure it does. Look up the CTE of a good stainless steel. Assuming a
2ft bar, the linear CTE is about 3x the tolerance for every degree F.Now try the same with the elastic modulus. :-P
You want to pay extra money for a 5um tolerance, go for it. I'll save my money and buy something useful.
Most anyone but astronomers.
You're proving my point.
