Nice collection of acronyms... For a good "glossary of terms", you can also go to our website (www.centralvirginiamachine.com) and read the explanation of many terms used by technicians and machinists, in order to better communicate with your technician and/or machinist.

now thats alot of acronyms ! i thought Computers had alot them... you hand type all those Flatrater? I'd spend a day just reading them all.

Hers one for ya. BRK - Its broke. Head for A.F. for help

How about FUBR. Frigged up beyond repair. Alot work went into this post. THANKS :grinyes:
