....But then what?

In my case, it was a stepper-driven contraption that drove an

IC engine camshaft between centers, with a Mitutoyo electronic

dial indicator resting on a cam lobe. The indicator was held in the

quill of a vertical mill - I could read a lobe into memory, pick up the

indicator. move the next lobe under it, and resume measuring, thus

not only measuring lift/degree, but the phase relationships between

lobes... Which you might think immutable, but sadly, not so...
