Don't argue with me Bob.
Look at the circled area, this is why I say ball endmill and full radius on the key. Notice the pinched pressure area, there already cranks in there, in you can bet on it.

this looks like what Casale did to mine after they shortened the shaft for the whirlawy , they recut the keyway and it looks exactly like that picture , i complained so much about it and the terrible re machine work they took 500 off the bill to replace the shaft
