I've been manufacturing my own crankset and have come to pretty much the only thing I can't do easily which is tapping for the pedals. I've been told that the taps from Park Tool are designed only for chasing dinged threads versus full treading which is what I am doing. I cannot think of any other alternatives since 9/16-20 is a special size, especially a left hand.
