I bought a 3" starrett mic a few weeks ago. It reads to the 10th. It did not come with a standard. And I don't have a 2" standard.
I started looking on ebay, and saw some nice Mitutoyo standards. Was about to buy them when I thought, hey, I have a bore gauge (Lufkin).
And I thought, I could setup the bore gauge with a 2" setup zero it, and then calibrate the mic. My 2" mic agreed with the reading.
Well , maybe it's not as accurate, maybe I can't trust the 10ths. But I believe it to be a solid setup.
What do you think?
