Instructions

1
Measure and mark a piece of 1-inch steel tubing at a length of 5 feet. Place it in a steel vise and cut it with a power hacksaw. Use a steel file to clean up the edges.
-
2
Tie a piece of string around a marker and measure off and mark a spot 3 inches out on the string. Hold the string at that point and draw a circle on cardboard. Use scissors to cut the round disk template. Trace the template outline twice on a 1/4-inch steel plate with a permanent marker. Cut the steel disk with a power hacksaw. Repeat the process for an a second, identical 6-inch disk of steel.
-
3
Drill a 1/2-inch hole in the center of both of the disks. Measure and use a reciprocating saw to expand the holes to a square, 1 1/2-inch width.
-
4
Measure and cut the auto-suspension spring to a length of 18 inches.
-
5
Weld one of the disks to the bottom end of the auto-suspension spring and the other to its top. When completed and standing vertically, the spring's upper and lower ends should be flat against the disks and perpendicular to a plumb line to the ground.
-
6
Slide the piece of steel tubing through both plates connected to the spring, forming an assembly that allows the spring to move up and down.
-
7
Weld the upper and lower surfaces of the bottom plate to the steel tubing at a point 6 inches above the end of the steel tubing.
-
8
Measure and cut two additional pieces of the 1-inch steel tubing, 12 inches in length. Lay the two 12-inch pieces on top of the upper surface of the top steel disk and against the sides of the steel tubing. Weld them in a parallel assembly attached to and touching the steel disk but not the steel tubing. When completed, the spring assembly will be compressed by the weight of a jumping rider.
-
9
Measure and cut a final piece of the steel tubing 12 inches in length. Weld it across the top end of the 5-foot piece of steel tubing.
-
10
Slide a 1-inch-square rubber crutch tip on the bottom end of the steel tube. Slide 1 1/2-inch-diameter bicycle handlebar grips onto the ends of the top-mounted piece of steel tubing.
