This six piece ring mandrel set is ideal for making PMC rings as well as for the traditional wax worker. The steel mandrel stand can be inverted so that you can work on rings from two directions. And the mandrel can be removed from the holder for handheld detail work. The multimandrel set consists of metal stand and six aluminum mandrels covering sizes 4 to 15 allowing you to make PMC rings in sizes 2 to 13. This size range allows for the approximate 2 size shrinkage when making rings from PMC. Wood stand (MAN-140.02) sold separately.
