[Figure 83] shows a drawing of the hook with size of stock to be used. The stock should be mild steel, 6½ by ¾ by ⅜ inches. To form the eye one end is heated and shouldered back one inch from the end, by hammering it on the anvil as shown in [Figure 84]. The eye is then rounded with the hammer and the hole punched with a hand punch. The hole is countersunk by hammering it on the horn as shown in [Figure 85]. The point is next drawn out and then the hook is heated in the center. It is cooled each side of the center and hammered over the horn to bend, then on the anvil as shown at [Figure 86]. A piece of ⅜-in. flat iron is set on the inside of the hook and the hook hammered to fit the iron. This leaves the opening of the hook uniform and just the size required. See [Figure 87].

Exercise No. 11.
Bolts may be made in one piece by upsetting the end of a bar, then squaring the head by driving the piece into a heading tool. A bolt may also be made by welding a collar around the end of a bar after which the head is squared.
