The bench anvil combination kit includes a round ring mandrel, round bracelet mandrel, a wood V-slot bench pin and the bench mounting system which has a flat anvil surface on top. The ring mandrel is hardened steel, perfect for hammering on, and has U.S. sizes 1-15 marked on it. The ring mandrel is 8.75” (22.2 cm) long plus the tang and is secured in the system with a thumb screw. The hardwood bench pin measures 6 x 2 x 5” (15.3 x 5 x 12.7 cm) and is cut with a V-slot. The bracelet mandrel is hardened steel and measures 6” (15.3 cm) long plus the tang. The bench pin and the bracelet mandrel fit perfectly into the opening under the anvil (not at the same time) and are held securely when the whole device is clamped to a table with the screw mechanism. The mechanism can clamp to a table up to 2.25” (5.7 cm) thick.
