Note: When using the sized jumpring mandrel, the size you use on the mandrel will be the inside diameter of the jumpring. The outside diameter will vary depending on the gauge of the wire used.
If you wish to create a great number of jumprings in any metal wire for chainmaille patterns, it would be best to use a motorized handtool and jumpring cutting system. This would produce consistently cut jumprings in large quantities.
