Durston 1309 The Complete Jump Ringer

The Durston Complete Jump Ringer is a jump ring making machine that is used with a Foredom No. 30 style handpiece and a flex shaft machine. With it you can mass produce jump rings from soft* non-ferrous jewelry wire like gold, copper and silver. The jump rings can be made with wire as thick as 13 gauge (1.85 mm). The inside diameter of the jump rings can be as small as 2 mm and as large as 12 mm. The outside diameter of your rings will vary depending on the wire diameter you use. The most popular sized wire for making jump rings used in the jewelry industry is anywhere from 0.8 mm to 1.0 mm.

The Complete Jump Ringer from Durston has many improvements over the original Durston Ringer. It now includes a coil holder which is part of the main base for greater stability. It also has a safety coil winder which can be moved and positioned anywhere on your bench. The increased mandrel length (4-3/4") and coil holder length means you can produce more jump rings at one go. The high stem gives more room for your hands and is movable in a complete 360 degree circle.
