In article , Harold & Susan Vordos says...

Wouldn't you say it's a matter of what you'd call *perfect*?

Now Harold, sure that's right.

He knows what he thinks, when he says 'perfect.' That
may not be what I think of when I say the same word.

This is why tolerances are put on dimensions.

He didn't put any tolerances there, so I felt free
to add in my own interpretation. "Perfect" means
no deviation from the correct geometry, at all.

Imagine a machine tool, with absolutely *no* rust
on it all....
