Thanks to all with the pics of gauges, etc. Now, to my main question: Once you have done this bit with the gauge and the math, and you have this ratio number, .... what do you do with it? Or, to put it another way: what does the number tell you? Or: Of what worth is this number? Or: what does it all relate to? Anyone care to give "us" the straight poop?<G> Regards, Joe Joe Garrett, R.P.T. Captain of the Tool Police Squares R I
