Okay, I believe I've succeeded in my "break the inch" quest. I make this right at 1 7/16" at the two widest edges of the grease rings that equals 1.4375. subtracting .451= .9865" No calipers or anything, just a good steel rule. I tried finding that post about the group measuring program, which I never did get around to trying. Couldn't find it.



Still failing miserably at the "speed" version of the challenge, but i'll keep trying.
