Specifically toward polishing beryllium spheres, it seems that if you want to polish very hard metals, such as beryllium, cryogenic treatment helps reduce the standard deviation of hardness. However, best practices would dictate that you polish them between copper v-grooves with a <1um diamond slurry, perferably oil based. Best finish would be with 0.25um mono, or poly crystal diamond. The v-groove depth should be one third the diameter of the sphere (in your case, about 0.026" deep for a 2mm ball).

If you have one in a metal alloy bottle that's been hardened using beryllium I'd say go for it.

You, sir, need to get laid.

Can he do that in one of those Berrilyum chambers he's obsessing about.

Cut and paste is a wonderful thing. You'll find that, and it's original reference, in a thread about terrorist cartoons on this very board.

Go figure.

We can only hope.

Dude, it's the off-season. How f**king cool would it be if ChiefsPlanet of all things was ranked #1 in Google when you searched for something highly technical and esoteric like "beryllium sphere"?

You know that would leave a world full of nerds scratching their heads.

Might baffle the Homeland Security folks too.

Wasn't Chiefsplanet 2nd on a google search for grape gatorade not too long ago??I hear ya..we should go after number 1!!!you go man!!!
"beryllium sphere" kicks ass!!!
:clap:

Hey! I think I stayed here when I was in Cambodia.

The cabin or the girl?

I figured it was a two-for-one deal.
