Yeah, blame John! :) For what it's worth, in the 25 years I have been involved in the mechanical packaging design of electronic enclosures, I have never heard of the word "faying". One can't help but wonder if someone just misspelled "facing".

Vancouver. -----Original Message----- From: Price, Ed [mailto:ed.pr...@cubic.com] Sent: April 1, 2002 6:47 AM To: 'EMC-PSTC List' Subject: Faying A couple of weeks ago, there was a thread discussing bonding techniques for ground studs. I suggested that MIL-B-5087 had some nice drawings showing typical accepted military practices. Of course, MIL-B-5087 has been superseded by MIL-STD-464, but you can still find electronic copies of MIL-B-5087. Jacob Shanker read through all of the 464 sections on Bonding, and then asked me if I knew what the term "faying" meant. It seems that MIL-STD-464 uses that term without any definition, as if it's a very common American English word. IMHO, I consider myself to possess a rather decent vocabulary. But "faying" left me puzzled, even after closely reading the context of the several citings in MIL-STD-464. It's certainly not in any common usage in my part of the world. I certainly wouldn't want to call something "faying" at any typical US military base. So, off to the dictionary web sites. 1. Britannica says: "not found". 2. Merriam Webster says: Main Entry: fay // Pronunciation: 'fA // Function: verb Etymology: Middle English feien, from Old English fEgan; akin to Old High German fuogen to fit, Latin pangere to fasten Date: before 12th century : to fit or join closely or tightly 3. Harcourt's Metallurgy Engineering Dictionary says: faying surface // Metallurgy: the interface between two metallic parts that are to be joined. 4. Finally, turning to Google in desperation for a simple explanation, I find pictures at: http://www.offroaders.com/info/tech-corner/reading/bolt-tension/bolt_ten sion .htm So after all this searching, I find that MIL-STD-464 "faying" is just a 12th Century Old English way to say "facing" or "mating" surfaces. I'm not sure how he did it, but I suspect John Woodgate is to blame for this.
