Rosenthal Collection Premium Solid Stainless Steel Ring Sizing Mandrel, Sizes 1-16
Rosenthal Collection's premium solid stainless steel ring sizing mandrel in sizes 1-16.
MegaCast Stainless Steel Ring Sizing Mandrel Sizes 1-16
MegaCast's stainless steel ring sizing mandrel in sizes 1-16 for forming and measuring rings.
A ring mandrel is one of those tools you do not think about until a ring comes off the bench slightly oval or a half size too small. The right mandrel fixes both problems: it gives you a hard, graduated surface for forming bands, truing up soldered rings, and checking sizes as you work. The main decisions are material and shape. Hardened steel mandrels handle hammering and forging, wooden ones are gentler on plated wire, and stepped mandrels keep wire-wrapped rings from tapering. This guide compares reliable picks across those styles, looks at size markings and grooved versions for stone settings, and helps you match a mandrel to the kind of rings you actually make.
