Use a circular saw to cut a single 8ft (2.4m) long 2in 8in (5.1cm 20.3cm) board into 8 equal lengths of 12in (30cm) each. Be sure to measure the length with a tape measure before cutting, so you don't cut the boards to the wrong length. These 8 segments will form the feet of the jump, so they should all be identical in length. The 2 posts that form the vertical side pieces of the standard jump will each be made from a 4in 4in (10cm 10cm) 6ft (1.8m) pressure-treated post. To keep the 2 posts steady, each will have 4 feet around its base. Stand each of the posts upright, and place 1 foot against each side of its base. Situate the butt of 1 foot flush with 1 edge of the post. Place the second foot so it butts up against the first, the third so it butt up against the second, and the fourth so it butts up against the third. Think of the feet positioning like hands on a clock. Each of the 2 high posts will have a foot located at 12, 3, 6, and 9 o'clock. Visually, they'll more or less resemble a pinwheel pattern. Once the feet are in place, you're ready to attach them to the vertical poles. On all 4 feet, set each of the 4 screws in at least 12in (1.3cm) from the outer edge of the post. A power drill is the most efficient tool for the job. Place a Philips head bit on the drill, and screw each of the deck screws firmly into place. You'll need 32 deck screws total. Deck screws are a little more expensive than other kinds of screws, but won't deteriorate in pressure-treated lumber.
