Achieve consistent bangle diameters with this cast iron stepped mandrel, ideal for forming round bracelets at the bench.

What it does

This robust, ten-inch cast iron mandrel provides four precisely machined, fixed diameters, eliminating the guesswork of tapered tools. Form repeatable bangle sizes from 2 to 2-3/4 inches with confidence. The square tang ensures a secure grip when mounted in a bench vice, allowing for controlled, forceful shaping of sheet metal and wire. Its solid construction offers durability for frequent use.

How to use it

  • Secure the tang firmly in a bench vice.
  • Hammer or form your metal around the desired step.
  • Wipe clean after use to prevent tarnish.

Who it's for

An indispensable tool for UK silversmiths, bench jewellers, and jewellery students. It streamlines the production of identical bangles and bracelets, replacing the need for multiple individual mandrels or imprecise forming methods for batches.

Common questions at the bench

What should I shape the bangle with?
A rawhide, nylon or wooden mallet moves the metal round the mandrel without thinning or marking it, so use one for shaping and truing. A metal hammer stretches and thins the metal and can mark it, and it dents a wooden mandrel, whose dents then press into your work. Use one only on a cast iron or steel mandrel, and only when you mean to stretch, planish or texture the bangle.
How do I get the bangle size I want?
If this mandrel is stepped, each step is a fixed size, so bangles formed on the same step match. If it tapers, mark the point where your bangle should sit with a pencil or a strip of tape and form each one at that mark. Either way, check the size with a bangle sizer or against a bangle that fits.
How do I keep the shape even?
Turn the bangle as you work and move along it a little at a time rather than striking one spot. If the mandrel tapers, take the bangle off now and then and put it back on the other way round, so it does not take on the taper. On a shaped mandrel, keep each side or corner of the bangle lined up with the matching face.
How should I look after it?
Wipe it clean after use and store it dry, where it will not knock against other tools. Keep the working surface free of nicks, dents and grit, because any mark on the mandrel can press into the bangle. Keep a wooden mandrel away from damp and direct heat so it does not split or warp. A light film of oil on a bare iron or steel mandrel helps keep rust away; wipe it off before you work.
