Draw the heavy end to a sharp, square point, making it straight on the side opposite to the shoulder and tapering from a point about 2-1/4 inches from the shoulder; this should also be made smooth with the flatter. Sketch _e_ shows this so far completed.
Beginning 1/2 inch from the shoulder, bend the 6-inch end backward through its smallest dimension, to a semicircle of 3 inches inside diameter. An outline of the required semicircle should be inscribed on a plate, or models may be made to verify it. Sketch _F_ shows the completed hook.
=72. Gate Hook.=—Fig. 52. Drawing, bending, and twisting. Material required: 7-1/4 inches of 3/8-inch square mild steel.
Mark lightly with the hardy on two edges 1-1/2 inches from one end, as shown at _a_. Form shoulders at these marks on three sides of the metal; do not make them too deep, as surplus metal will be required for bending here. Draw the metal at the shoulders just made, continuing to the end to 5/16 inch round and 2-1/2 inches long. Sketch _b_ shows the work completed to this point.
Mark the opposite end on the same edges and in a like manner 4-1/2 inches from where the first shoulders have been formed; form shoulders at these marks and also draw down to 5/16 inch round, making the extreme end a smooth, round point, 2-1/2 inches long from the shoulders, as at _c_. Both of these ends should be round and smoothly drawn with the hand hammer.
[Illustration: FIG. 52.—STEPS IN MAKING A GATE HOOK.]
Bend the straight, round end from the side _e_ to a right angle, proceeding as follows: When placing the work on the anvil, have the side _e_ uppermost and the shoulder projecting over the edge of the anvil the thickness of the round, or 5/16 inch; then when the metal is bent, the inside corner will be formed at the proper place and the shoulder will readily form into a right angle on the outer side. Light upright and backing-up blows will aid in forming the right angle after it has been bent, provided the piece is held with the round end vertical and resting on the face of the anvil. If such blows are used while it is being held over the edge of the anvil, they will reduce the sectional dimensions and not materially aid in forming the angle. Sketch _d_ shows this angle in solid lines. Now form the round portion of this angle into a circular eye, making the inside diameter 1/2 inch, with the center on a line with the center of the main stem. Sketch _d_ shows this eye in broken lines.
