This is my ball turner.

You will see there is a scribed line on the base. This denotes the axis of rotation. To turn a perfect ball this line is aligned with the axis or centre line of the lathe. I then adjust a backstop to prevent the cross slide from going past this point. The cross slide is then withdrawn to commence cutting. The other scribed line (on the turret) is used to set the diameter of the ball required - distance from this line to the cutting tool = the radius. The first (only so far!) ball I turned using this method is the one in the picture and is to all intents perfectly spherical apart from the collar.
