Master ring resizing with this dual-action jewellery machine, precisely stretching and reducing bands at the bench.

What it does

This robust bench-mounted tool efficiently alters ring sizes. Its hardened steel, six-spline mandrel smoothly expands plain bands; the mandrel is stamped with European ring sizes 1–36 (UK sizes are letters, so convert before stretching). For reduction, a rotating plate of polished reduction dies offers controlled shrinking. The substantial cast-metal body and long lever ensure consistent, measured force application for precise adjustments.

How to use it

  • Securely mount the machine to your workbench.
  • Select the appropriate mandrel or reduction cavity.
  • Apply steady lever pressure for size adjustment.

Who it's for

Essential for UK bench jewellers and repair workshops, this tool streamlines resizing plain gold, silver, and other malleable metal bands. It replaces separate stretching and reducing tools, offering a consolidated and efficient solution for professional workflows.

Common questions at the bench

What rings can I stretch with it?
Plain bands, as this product's description says. Do not stretch a ring set with stones, a hollow ring or a ring with engraving or a pattern you want to keep: stretching can loosen stones, split the metal or distort the pattern.
How much can I stretch a ring?
Only a little: stretching makes the band thinner and narrower. Stretch in small steps, check the size after each one and stop as soon as it fits. For a bigger change, cut the band and add metal instead.
How do I check the size?
Measure the ring on a ring sizer or a marked ring mandrel before you start and after each step. If this product's description says its mandrel is marked with sizes, those follow the standard it names; UK ring sizes are letters, so convert with a ring size chart.
How should I look after it?
Wipe it clean after use, keep it free of grit and metal filings, which can mark the inside of a ring, and store it dry.
