How do I electroplate a sphere?

I have four .5" diameter sterling silver basketballs (castings) that my client wants me to gold electroplate (3 gold and one nickel, actually).
I have a complete jewelry workshop and have been at it 30+ years, so I'm not seeking information on how to plate, instead I'm wondering how to hold the balls to plate them.

Hi, Robert.

I would use an egg dipper shape rack, similar to what a child would use for dyeing easter eggs. Just move the spheres 3 or 4 times during the plating process, and do it quickly so the nickel plating does not have time to passivate. Good luck.
