Durston 1309 The Complete Jump Ringer

A jump ringer turns soft non-ferrous jewelry wire into consistent, repeatable rings in production quantities instead of one at a time at the bench. The Durston 1309 Complete Jump Ringer is a bench-mounted machine that works with a Foredom No. 30 style handpiece and a flex shaft, giving precise control over ring size and consistency. As the coil builds and the saw takes its steady cut, finished rings collect in a clean, predictable rhythm.

Features

• Built for mass production of jump rings from soft non-ferrous wire
• Updated base-mounted coil holder for improved stability
• Safety coil winder that can be positioned freely on the workbench
• Extended mandrel length allows longer coils and higher output per run
• High stem design gives increased hand clearance and full 360° positioning
• Comprehensive mandrel set covering a wide range of ring sizes

Compatibility

For use with a Foredom No. 30 type handpiece powered by a flex shaft machine. The flex shaft and handpiece are sold separately.
