The flange is the culprit for the noise. I'm very satisfied with that bit.
The newer sprocket with flanges on both sides made a bit of noise from the beginning. My first sprocket only had the inside flange which had never made contact with the belt as the belt, from the very beginning, was riding about 3/8" away from it. The noise in the first one was due to the belt eating the sprocket and the buildup of aluminum debris which made it worse and wore faster as more aluminum dust was created. Spiral of death as it were. When it was finally removed the wear was very deep, as in about 1/8" worn off!
I tried the silicon but that does not last. There is no binder, like an oil, to keep it there. The carrier in most silicon spray is usually an aliphatic naphtha which evaporates almost immediately. So you have the silicon but nothing to keep it there.
Going to try a very lightweight oil such as WD-40 and see where this goes.
Another observation is the the bevel box gear shows absolutely no sign of degradation. Some sort of steel. Too bad the rear sprocket isn't made the same way. It would probably add another 15 lb. or so. The Morgan aluminum sprocket started life as a simple casting then was finished of by milling. A steel rear would have to be totally milled from the very beginning significantly adding to the cost.
OY, what have I started?
