here is a video with a much easier way to make one. just need a hammer or spoon, drill, file and some sandpaper. i think i am actually going to give it a try. i have a bunch of junk halves i can try with. https://www.youtube.com/watch?v=yOWkwUqzqPk&list=FLnA_S6-zjwigvzWbXBePyQg
Im surprised no one has mentioned this yet, but I want one made from a $10 gold indian, actually that really is exactly what i want for my wedding band
IMO, that would be too soft. Easily bent and marked up. My 10K wedding band got hit and bent. It had to be cut off of my finger.
