Chuck;
I truly find it extremely hard to believe I am having this conversation with you of alL people. I have a bit of knowledge of your background. Like I have said several times "JUST DO THE MATH". it's simple trig. I am not disputing what Clymer ground there reamers to or what SAAMI specs say. It's just that those figures "DO NOT PRODUCE A LONG FORCING CONE". That's all I am saying. I simply quoted the angles from the shop drawings for L C Smith & You told me they couldn't be right because they were a lesser angle than these "NEW MODERN LONG CONE REAMERS". Well a 5° angle reamer does not cut a long cone, simple as that. I don't currently have an L C Smith to actually measure, but the 3°1' & 3°13' figures came directly off of a shop drawing as published in the PLans & Specifications book by Brophy, I have no reason to dispute them. What Clymer is cutting their reamers to today has no bearing on what Smith was using in 1935.
