{"product_id":"durston-1309-complete-jump-ringer","title":"Durston 1309 The Complete Jump Ringer","description":"\u003cp\u003eA 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.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt for mass production of jump rings from soft non-ferrous wire\u003c\/li\u003e\n\u003cli\u003eUpdated base-mounted coil holder for improved stability\u003c\/li\u003e\n\u003cli\u003eSafety coil winder that can be positioned freely on the workbench\u003c\/li\u003e\n\u003cli\u003eExtended mandrel length allows longer coils and higher output per run\u003c\/li\u003e\n\u003cli\u003eHigh stem design gives increased hand clearance and full 360° positioning\u003c\/li\u003e\n\u003cli\u003eComprehensive mandrel set covering a wide range of ring sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eFor use with a Foredom No. 30 type handpiece powered by a flex shaft machine.
