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.
