Forming and enlarging rings on bare steel risks marking soft precious metal. This wooden triblet does the same job gently — a smooth, continuous taper over its full 12 inches, with the length to handle wide bands and the entire adult size range. If you are weighing up steel against wood, stepped against plain, our guide to choosing a ring mandrel compares them.

The distinct turned handle section gives a secure hold while you hammer, and the unmarked taper lets you shape and true rings by eye. A robust, simple tool built for repeated use in a busy workshop.

  • Full 12-inch (approx. 305mm) length accommodates the entire adult ring size range.
  • Turned from smooth wood to prevent marking or scratching precious metals during forming.
  • Continuous, unmarked taper is ideal for shaping and enlarging rings by eye.
  • Features a distinct, turned handle section for a secure grip whilst hammering.
  • A robust, simple tool for repeated use in a busy workshop environment.

Who it's for

A workshop essential for UK bench jewellers, silversmiths, and jewellery repair specialists. It is also an excellent, hard-wearing forming tool for students and apprentices in jewellery-making and silversmithing courses.

Common questions at the bench

Can I measure ring size on it?
Only if this product's description says it is marked with a size scale, and then in the sizing standard it names. UK ring sizes are letters, so convert a numbered size with a ring size chart. A mandrel with no size scale is for shaping, not measuring: check the size with a ring sizer or a marked mandrel.
What should I shape the ring with?
A rawhide, nylon or wooden mallet moves the ring round the mandrel without thinning the metal, so use one for shaping and truing. A metal hammer stretches and thins the band and can mark it: use one only on a steel mandrel this product's description says takes hammer work, with light blows, and only to stretch the band or to set crisp corners and edges on a shaped mandrel.
How do I keep the shape even?
Work round the ring a little at a time rather than in one spot, and check it often. If the mandrel tapers, take the ring off now and then and put it back on the other way round, so the band does not take on the taper. On a shaped mandrel, keep each side or corner of the ring 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 inside of the ring. A light film of oil on a bare steel mandrel helps keep rust away; wipe it off before you work.
