Hello,
I have recently started making silver rings. I make them using blank metal lengths and solder them. I made a couple that ended up being the right size, I'd used a calculation I found that allowed me to find out how long the metal needed to be.
But when it came to me making the rings I'm going to sell I found that the lengths I cut did not make the ring size I needed. I checked and rechecked my calculations and measurements but to no avail.

So I'm wondering if anyone has had a similar issue or knows what I might be doing wrong.

TL;DR. My rings are coming out the wrong size with the right measurements!
