Ragtop,
I am no machinist but from the 440source site it definitely seems like there will be extra metal on the counterweights to remove above the drilling for balancing. I don't know which of the three machine processes that have to be done to make this crank are considered major but I guarantee you that finishing up this crank will be more than just the balancing price. Doesn't seem like it should be much more to turn the counterweights down but my poor machine shops around here don't even want to do it! Maybe someone here can give us a guess on how much this would cost. Like I said though still a good deal in my book.
