Steel Ring Mandrel/Triblet with Guage Ring Mandrels are most oftenly used to form a ring with a mallet, truing the form once it has been soldered, forcing the piece up the mandrel and enlarging it. This is a 2 IN 1 Steel Ring Mandrel. On One side you have the plain ring mandrel and on the other side you have marking going from A to Z plus 1 to 6.
