Bolt a piece of metal to your rotary table then mill a circular boss to locate your rims on center. Then you can place the next one on the table and it will be located. You will have to have a nice fit though. Make it big enough to have your studs for the clamps to screw in or double nut by using the slots then a nut to hold plate then long enough to clamp rim down.
