This method can make a ball on a shaft where the "angle" the ball makes is about 270º out of the 360º possible. The limit is largely the attachment hitting the chuck. It will also be noticed that to get this angle the ball has to be made a long way out from the chuck. To get the best possible result the left side of the cutter needs to be removed.
