The hook is made from iron. [Figure 51] represents the dimensions of stock for the hook. The lug is welded on, and the ends of the bar are rounded ready to be formed. After the stock is cut, it is upset six inches from one end to enlarge it so that the lug can be welded on. The stock from which the lug is made is cut 3½ inches long, upset on end, and split in the vise ½ inch deep as shown at [Figure 52]. The split end should be formed as shown. In welding, separate heats are taken, and the lug is jumped onto the bar as shown in [Figure 53]. The first blows are struck directly on the end of the lug, then the lips are welded. [Figure 51] shows the length of the piece before the knobs are formed. In making the knobs at the end, they should be upset as shown in [Figure 54]. They are then hammered as shown, and finally rounded. The lug is next cut the proper length, and a shoulder is filed at the end. The chased lines are now cut on the front side. In forming the piece, it is heated and hammered over the horn of the anvil, starting to bend at the end first, and working toward the center. In bending anything of this kind, always start at one end, and finish as you work toward the other end. See the drawing of the bent hook at [Figure 55]. The end of the lug is next heated and caught in a vise, the plate is set on and riveted tightly. The work is smoothed with a file, heated to darken it, and oiled.
