1
Ride as many jump ramps as you can to figure out what you like and dislike about other ramps.
-
2
Draw a design of your ramp on paper to get an idea of what you want to build. Determine how much transition you want and how high you want to go.
-
-
3
Tie a string to a pencil. The length of the string will be the transition of the ramp. A longer string equals less transition, and a shorter string equals more transition. An 8-foot string is a good general length, but after you draw it out, double check to see if that's what you want. It's easy to change or re-do your transition prior to cutting.
-
4
Place the tip of the pencil on the corner of a sheet of plywood and hold the string out straight along the short edge (the 4-foot edge) of the plywood. Hold the string taut so that it it extends well beyond the plywood, parallel to the edge of the plywood.
-
5
Anchor the string at the non-pencil end, keeping it taut, and draw the pencil along the plywood to sketch your transition.
-
6
Look at what you drew and decide if it is the right transition for your jump ramp.
-
7
Cut the transition out of the plywood with a skill saw.
-
8
Trace you transition piece onto another piece of plywood and cut that one out too. You should now have two identical pieces.
-
9
Use two-by-fours of equal length to brace the transitions together at each corner. Drive nails from the outside in.
-
10
Use more two-fy-fours to brace along the curve of the transition, to support the riding surface of the ramp.
-
11
Nail a flexible piece of plywood onto the top surface of the jump ramp. Double ply is even better.
-
12
Use a flat, thin piece of metal to make a smooth connection from the base of the jump ramp to the ground. Make sure there are no exposed screws or nails on the riding surface of the jump ramp.
-
13
Test the strength of the ramp with your body weight before launching off it.

Tips & Warnings
By making the ramp four feet wide, you can save yourself from having to cut the plywood for the riding surface.
If you plan it right, you might be able to get both sides of the transition out of the one piece of plywood.
The stronger you make your jump ramp, the longer it will last. However, you may need to consider how much you're going to be moving the ramp around. Stronger often means heavier.
Make sure people wear proper padding when riding your jump ramp.

Where can I come across a "flat, thin piece of metal to make a smooth connection from the base of the jump ramp to the ground"?? I've just built a quarter pipe and need one for the transition from ground to ramp. I've been scouring home depot and lowes with no luck. Any help is most appreciated. -

We use scrap wood and some concrete blocks. You pile a few concrete blocks on top of each other until they reach the height you want the ramp. Now you have to decide if you want a scary big air ramp or just a little jump for fun. If you want big air, don't put any supports under the wood for the ramp. If you want the little one, support the middle of the ramp by putting blocks underneath it.

Make the base a triangle: __ /\\ \\ __ / \\ \\__ Making the triangle made of 2 peices of plywood nailed together.Then a greater peice of ply wood for the ramp, then 2 peices of plywood for a more griped landing.

It is really easy. Make it vertical (but don't go too far). Make sure it is flat, or you will lose your balance and not jump as high.
