I use a process similar to Jon Elson's. I use a lathe face plate and 3 adjustable supports. With an indicator in the spindle I drive X and Y to dial the surface of the face plate parallel to the XY plane. I then go to the center of the face plate and sweep the face plate adjusting A and B as necessary.
