I have done rings like this from flat stock like you have. stick it in a vise pointing up and star tthe bend I dont close the vise all the way.bend a bit and slide it down and bend some more. You do not have to make a nice circle, Just get the ends so they will butt together and you can weld them. I make them round while cool. The heel of my anvil has a bit of radius on both side. I place the ring across the heel and turn it until a part of the circle that is out of round by being higher than the rest is above the anvil. tap that with a smooth hammer. turn some more and find high spots and tap again. After you do the first one you will find this is not a tough task. Just remember to only hit the parts that come above the anvil asa high spots. Have fun |
