Things they don't tell you in the books so I'm asking you lot

How obvious!  Mutter mumble.

Clearly, only an ignoramus would ask such a question. Especially one who’s been applying DOC’s for about 65 years without knowing it. AND worst still, one who has been surrounded by plastics acronyms since 1950.

Perhaps for us oldies (who, like me, are too lazy to work them out), ME could collect and build a useful acronym glossary?

Thanks for coming to my rescue Nick!

Adam’s posting is to be commended, so "Well done, Adam!"

The fact is, unless we can demonstrate our competence as a genius, or have become a professional student, there probably isn’t enough time in our lives to qualify in `Everything’.

Before clockin-off, one of my favourites stems from when, as a fairly recently promoted technical service officer smartly dressed for the occasion, I was `advised’ by the works manager of a plastics factory as he dashed past me that :-

"All your theory goes down the drain in this factory, you know!?"

With his overcoat flapping in his slip-stream, this manager had blustered past me about half a dozen times on his way to and from his office. Presumably that was necessary to keep the wheels turning? But, how did he know that I was an academic, or anything else about me for that matter?

Soon after his startling revelation, the moulding machine `jammed’.

Then, as if it were standard practice, four or five of his operators took hold and began swinging on a long length of 6x4 timber, trying to free the machine. That was the moment when it was pertinent for me to leave discretely, wondering if a drain had blocked.

Now, at least, I know what DOC means! Thanks again Nick.

Ian (S C),

So would OD = OFF DIAMETER? Or am I entitled to accept that it’s still short for OUTSIDE DIAMETER?

By the way, watch out for those big coils of blue steel. They have been known to find their way inside trousers.
