Gene: I understand, and the method I am suggesting which uses the bridge top as a zero point allows for the measurement of both components which are then netted. Do you zero on the speaking length? Paul Yes. I have never been able to consistently zero on the bridge, measure both angles, add them and come up with the same total number as when I zero on speaking length and measure the tail to get a total. They should be the same?? Gene -------------- next part -------------- An HTML attachment was scrubbed...
