Nor mine, doric. But, seeing how things have been on the forum lately, maybe another form of tolerance is in order? Wouldn't want to scare anymore people off from contributing I guess I'm trying to say.

On that note_

"For example, you are producing ball point pens with a ball outer diameter of 0.35 mm. Acceptable balls range from 0.34 to 0.36 mm. Subtracting the maximum and minimum diameters, the process tolerance is 0.02. In order to accurately measure these balls, you must use a gage capable of detecting several differences in this range. Using the Rule of Tens, calculate 10% of the process tolerance. This means your gage must be able to detect a difference of at least 0.002 mm between balls."

So in other words you used to be really good at measuring balls. Lol... sorry couldn't resist. :D
