pinning anomaly and question
Well, I wondered about wedge geometry, too, but I just got it all back together and here's what I've got. I used Microfastener's nut and bolt combo with fresh everything and tightened her right down. The "soft spot" was still there so I took another turn on the wrench and the problem seemed to get better...I took another couple of turns on the wrench and the problem got a lot better. I worked the blade through its arc a few times and it loosened up and started the soft spot thing again. I got under bright light and noticed that the thrust washer (on one side) was lagging then catching up while the blade moved from soft to hard spot. That begs the question...are the thrust washers supposed to remain solid in their positions during the rotation of the blade or do they rotate with the blade. Or beyond that, do they sit tight on the blade and rotate on the scale surface. I have to assume that they must sit tightly on the scale surface and only move against the blade in its rotation. I assume this from taking razors apart only to find that the thrust washers have stuck to the scales and not the blade. Anybody got any ideas, here? My next step will be to put a dab of superglue on the thrust washers in their proper positions and see if that alters the results. Any thoughts about this procedure?

Pixelfixed, thanks for your support. I was just sitting here fiddling with the disassembly for tomorrows pin up and noticed that my Microfastener bolt was thinner than 1/16" and wondered if that had anything to do with it. I got my piece of 1/16" brass rod and fit it up by hand and squeezed it all together and guess what?...no binding! I may be on to something here. I'm all in for tonight, but stay tuned as I'll be anxious to get after this deal in the morning. When I was in 8th grade, I was given a math problem that I just couldn't solve. My aunt was visiting at the time and she offered to call her nephew who was, at that time, head of the mathematics department at the Jet Propulsion Laboratory in Pasadena. After about a 3 hour wait and using all the resources available to him, he called back to say that he and the staff had come to the conclusion that the problem was written is such a way as to not be solvable. Don't for a moment think that I wouldn't send this thing off to MIT!
