The 10pm thread (archived)
The big anti-hijack thread.....
Talk about anything, but if this works than we don't have to keep looking around all the threads to see who is still on tonight, and every night, or even every day! Talk about the chiefs, talk about tomorrow, talk about football, politics or even how to do flooring and the applicable budget. What you're drinking, how hard it is to sleep, etc. Every thing is acceptable in this thread..... http://www.timeanddate.com/worldcloc...om.html?sort=2 see for yourself, it is ten o'clock somewhere.

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).

You know that would leave a world full of nerds scratching their heads. Might baffle the Homeland Security folks too. |
