Ken Howell,<P>I have read and understood (well most of them anyway - that math part from another thread still gets me ) your posts here and throughout the many threads that this topic has spawned, and I must say I agree with you. <P>I really wonder what the actual pressures are running at when such things as variances in case hardness, out of round chambers, steel strength, initial deflection, and human error in measuring are taken into account.<P>As I mentioned before, I am hoping to obtain strain guages in the near future. And while they do have their problems, the pressures obtained by measuring a consistant factor, like you have pointed out, should produce closer results than the measuring of an ever changing factor such as the case.<P>Turok<P>------------------<BR><B>Make it idiot proof, and some one will make a better idiot</B>
