SECONDS expanding ring turning mandrel
These mandrels are seconds/faulty they will not produce concentric rings, but they can be used to hold rings steady whilst you add inlay such as crushed opal
We would normally return these to the manufacturer, but we thought they may have a use rather than being scrapped
Made in high quality Stainless Steel
Fits ring sizes F - Q (USA 3-8). The mandrel also accommodates half sizes
It fits comfort ring cores to help make turning rings simple and easy.
Just mount the ring core on the closest sized mandrel step, then lightly tighten with the allen key and the mandrel will produce a solid grip on the ring core.
