CHAPTER VIII BOX FORGING A BOX forging is one that has been formed in the shape of a box, and is generally used for the base of some piece of ironwork. Fig. 78 shows a candelabrum with a box base. A base of this kind is formed from a flat piece of metal by bending the edges over to form the sides, giving it the appearance of stability and yet leaving it light in weight. In forging a base of this kind two methods may be employed: one, where the shank or upright piece is welded to the flat or base part by a jump weld; the other, by forging the shank and base from one piece of metal. To forge the base from one piece, a round or square bar may be used, either of soft steel or Swedish iron. Common iron will not do, as it is likely to crack while working up the form. The first thing to do is to determine the size of the base and the amount of stock needed. In this kind of forging plenty of stock must be allowed, as it is better to have too much than to be short when finishing the forging. After the stock is cut it is heated and fullered as shown in Fig. 79, at A. The part that is to form the shank is now heated p.126
