Ring Stretcher & Reducer — Bench Sizing Machine, European Sizes 1-36, Wood Handle, Silver

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.
