How to make Jump Standards

A Pair of Jump Standards are made out of two two-by-fours about eight feet long. After planing them smooth on all sides, measure off two feet from one end of each, and mark off the remaining six feet in inches, as shown in Fig. 259.

After squaring these divisions across the poles with your try-square, bore holes three-eighths of an inch in diameter through the poles at each division. Then, with a small brush and black paint, mark off each foot with a band extending around the pole, each half foot with a narrower band, and each inch with a short line, as shown in the drawings. Letter the foot divisions 1, 2, 3, 4, etc.

When both standards have been finished, bury them in the ground to a depth of thirteen inches, eight feet apart. Cut two wooden pegs similar to Fig. 261 to fit the holes, and procure a nine-foot pine or hickory pole one inch thick for a cross-bar (see Fig. 260). When the bar is placed upon the pegs, the distance from its top to the ground should correspond with the figure on the upright. If not the same, raise or lower the uprights until the error is corrected.

With a pair of these standards there is no danger of injury by tripping over the bar, as the latter will fall off with the slightest knock. There is one disadvantage in using a stick, however, it being easily broken if jumped upon. Because of this, a rope with a weight attached to each end, as shown in Fig. 262 is often substituted. The ends of the rope are hung over the pegs in such a way that it will slip off the pegs when struck. The weights should be just heavy enough to prevent the rope from sagging in the centre.
