The two in the foreground are also derived from the same source. Obviously, I liked the square head with eight head bolts better than the original round head. I also eliminated the spacer on the main shaft that positions the eccentric by doubling the thickness of the upright and machining the main bearing such that it is also a thrust bearing for both the flywheel and the eccentric. I like the thicker pedestal better, but that is subjective.
