A bracelet mandrel is essential for making bangles. As I showed in a earlier blog post I solder my bangles and after that they are not round. They are then hammered on this wonderful tool! I clamp it into a vise, slide on the "not round" bangle to the stepped section that it fits on and hammer away. This photo shows a round one, I also have a oval one. I like the stepped sections, the bangles seem to sit better on them than they do on a tapered mandrel. It's heavy so watch you don't drop it on your toes!
