Morning all. Can anyone tell me if there is a formula or technique to do this. I’m not too bad with thinner wire for rings but if I want to use a heavier gauge I really struggle. I saw and file as straight as possible and I’ve tried by using a gadget to form the circle and obviously the inner edge meets before the outer edge. I’ve also tried making a ‘D’ shape but still struggle with the join. I was told just file it to make it meet but the gap appears in a different place.
Hope someone can help. Thanks
