I wanted to check the flatness of my lapping plate. My wife is a machinist and took it to work with her to see what could be done. Cool, one of those high tech calibration guys should give me some good input I thought. Regular machinist aren't allowed in their area for some reason. Her foreman took it over.

They stand there looking it over. Set it down on their giant slab and try to rock it. ( you know, poking on it)
Then dude comes back and says. It's pretty flat. gimme a break. sheesh. I know it's pretty flat. So much for the idea of making a comparison between plate flatness and lapped stone.
