Guys,

You know....when I sit here reading all that tech talk and specs discussion you two had flying back and forth between each other, it had me singing that Wizard Of Oz Tune to myself. (-That tune performed by Ray Buldger the Scarecrow.) But I do now understand the general drift of what you are explaining, and how these charachteristics work.
Nice to know I can rely on you smart guys. They sure didn't teach me this stuff in my High School Shop Class!
l
I have an even tougher question for you: It seems my extra +1/2 to +3/4 incidence didn't screw anything! How'd that happen?!!
(-not having to tear up and correct what I just completed !)

Thanks,
Randall
