Hi all;
I did a bit of further checking. My close Estimated method of taking the median diameter of the old bore size & new bore size times Pi times thickness of metal removed "Per Side" times length of bore thus enlarged is actually not a reasonable estimate. It is in fact Spot on & 100% accurate for the Cu Inches of metal removed. Sort of surprised Rocketman didn't call me on this one, guess he was just being his normal kind self.

Quite often there is more than one way to figure something. For instance when I figure the area of a circle I normally use PiD�/4 rather than the normally quoted PiR�. Answer is the same both ways as R = D/2 then R� = D�/4.
