As usual I don't have plans Chuck but here is one I made, they're called a slip roll I think.
Seams the larger the rollers the less chance of them slipping while your rolling stock, I also tied the two lower ones together with a roller chain drive. I've seen commercial ones that tie one of the bottom rollers to the top one with a gear drive.
I've rolled 5/16 plate 13 inches wide with this one. Takes amazingly little torque to turn the rollers when forming the ring.
Because of the roller spacing mine leaves about 3 inches unrolled at the end of the stock, but if I weld the ends together and roll the completed ring it comes out round.
Oh the top axle is removable to get the ring out.

Free advice is worth exactly what you payed for it.
