40 mm coin vise

Two-piece aluminium vice that holds a 40 mm coin blank for machining both faces. Each jaw has a 90° V with a 4 mm ledge set 2 mm below the top face, so the blank seats flat and stands proud of the jaws for facing and engraving. The fixed jaw locates on two M5 screws and the moveable jaw slides on 13 mm slots to clamp the blank. Both jaws nest on a 100 x 70 mm offcut of 5 mm aluminium plate. Suits Carvera owners making coins, tokens and medallions.
