JDG Ring Mandrel

JDGs standard expanding ring mandrels fit both JDG and Artisan Comfort Kit ring cores to help make turning rings simple and easy. Just slip the ring core onto the step that fits best, make sure it’s properly seated, then lightly tighten with the allen key. This will cause the mandrel to expand slightly to produce a solid grip on the ring core.
