Jeff,

Thank you for the thorough explanation. I believe that I was able to follow most of it as I was somewhat able to visualize what you were describing. If I actually had a few different size/style cams in front of me then it would probably be even easier to digest. You and I need to get together again soon.

One question right off the bat though....why is the radius used as opposed to the diameter?

Lastly, I have some dual cams from a Browning Afterburner laying downstairs if you want them to play with.
