Sherline Products, in collaboration with Bryan D. Drummond (gem cutter and goldsmith), designed this Expanding Ring Mandrel specifically for making and modifying rings on the Sherline lathe.
The mandrel is manufactured from 12L14 steel and features a black oxide finish for rust prevention.
It is designed for use with stepped ring collets manufactured by Ring Tech (Faceting Collets Stepped). These Ring Tech collets are known for their excellent quality and superior design, and, like our machines, are made in the USA.
If you are using a brand of collet that is shorter than the Ring Tech collets, the mandrel includes a spacer washer that fits against the shoulder of the mandrel. This allows shorter collets to be properly positioned at the front of the mandrel.
