This week I was asked by a friend to size down a large mans, celtic weave ring. It was an interesting task because only whole sections of the pattern could be removed. I started by removing a single section of pattern, but this did not reduce the size enough.
So I had to remove another section but, unsurprisingly, this made it too small.
The only solution (that I could think of) was to solder up the ring and then stretch it to the correct size using the ring expander/reducer machine.
I admit I stretched the ring up rather too many sizes than I probably should have. However it was not difficult and I suspect that this was due to the fact that it was not a solid piece of metal.
Edit - The finished ring was returned to the customer and I later got this message: "Just to let you know, it fits him just right. Thank you xxx"
