Thread: Thanks Goober

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.

I think Ive met that guy.

Thank you so much for that great laugh Now that was funny......

So, do those guys work for NASA?

Maybe you should ask them how they lapped their giant slab?

HEE they could work for nasa

I heard more. their fear was to touch the abrasive with any of their tools, my wife was advised not to use her comparator on them either. So there went my weekend project.

I would not be interested in buying her a new 400$ gauge

they do have an optical comparator... maybe if there is another slow day some measurements could be gathered.

Nice.

They didn't even get a flashlight to put behind it or anything?

Maybe you could lap your highest grit hone with it and see if they'll run their tools over that surface, that'll give you a more usable figure anyway. Maybe do it a few times to get a nice average.
