A good friend and neighbor works for Sodick, a manufacturer of wire EDM machines. After many discussions of how best to cut the keyways in aligment with the crankpin bores, I got an offer to cut them with a wire EDM machine.

The procedure was to find the center of the axle bore and save the positions. Then re-thread the wire in the crankpin bore and find the center. Then the angular difference between thr axle bore and the crankpin bore is calculated, and the machine axis is rotated about the axle bore and the keyway is cut. All the cutting is below the electrolite and is not very visable.
