Each wood mandrel securely mounts on the steel base and rotates 360°. The smooth round steps, marked from sizes 4 to 13, allow you to precisely size rings when wax working or using metal clay. These mandrels can be removed from the stand for handheld use. The stepped mandrel is 12-5/8 inches; the unmarked, smooth mandrel is 11-1/2 inches.
