Formula for Rolling Sheet Metal Rings

Today, I had to fabricate some .188 thickness stainless steel parts. Two of the items had to be rolled into rings. I would like to explain how to determine the proper length of material to be used when rolling metal into rings. You start with the overall diameter of the ring. For example lets use 24" outside diameter. Material is .188 thickness.
Take .188 x .6 (60% of the metal thickness)= .1128. Take .1128 x 2 = .2256. Then the diameter 24" - .2256 = 23.774 flat length to make a 24" O.D. Ring. Hope this is a help for any projects you may have that require a ring to be rolled.
