Interesting piece Rob, but in it Ford is a bit contradictory.

He says that a rule is graduated in increments accurate to the measurements indicated on it but a scale is graduated in increments proportionally larger or smaller than the measurement indicated. He then goes on to mention a patternmaker's shrink rule, which cannot by his own definition be a rule, because the increments are not set out accurate to the measurements indicated on it. It must be a shrink scale.
