The bench anvil combination kit includes a ring mandrel, two wood bench pins, an oval bracelet mandrel, 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. One 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 second hardwood bench pin measures 7 1/4 x 2 x 1 and has a round and an oblong cut out in addition to two v-slots and square and half round sawing support. The bracelet mandrel is hardened steel and measures 6” (15.3 cm) long plus the tang. The mandrel is aprox. 7 inches wide by the tang and aprox. 4 inches around at the base. 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.
