Wow! Very meticulous work indeed. Intricate chainrings for sure. Nice touch leaving just a little nub where the inner web was removed.

All of these parts are very impressive, but I am most impressed by the calipers. There is no jig that will allow that kind of work on a milling machine. That was all freehand grinding and requires a steady hand. If you compare the calipers you can see the slight differences between them. Excellent work. And then to polish everything except the relief. That also requires hand work. You can't do that on a buffing wheel.

John, shouldn't that stem binder nut be turned around so that one of the flats contacts the flat on the stem? You also might want to get those brake blocks oriented correctly or someone is in for a big surprise the first time they put on the brakes!

Thanks for sharing that lovely piece of work. I can only imagine how long all this must have taken.
