Introduction: Easy DIY BMX Jump

By

This jump is a small, easy to store, portable jump for BMX. It is easy to make but requires a planer. I would recommend it to any BMXer, and would say that an intermediate to advanced builder could make it.

Supplies

To Make This Project, You Will Need:

  • x2 15mm ply offcuts, 300mm x 1200mm. These will be the side pieces.
  • x1 15mm ply offcut, 500mm x 840mm. This will be the ramp.
  • x6 70mm x 35mm construction pine, 467mm long. These will be the supports.
  • A circular saw
  • A planer
  • A pencil
  • A tape measure
  • A set square
  • A metre ruler
  • A drill
  • A countersink drill bit
  • A screwdriver drill bit
  • Screws (About 60)

Step 1: Cut the Side Pieces

  1. Get your 2 pieces of ply that are 300mm x 1200mm. Lay them out on your workbench so that the longer sides are facing you.
  2. On the edge closest to you, mark a point 800mm fro the top right corner. This will be point A. Draw a line from the top right corner to point A
  3. From point A, use a set square to draw a dotted line across the ply.
  4. Mesure a point 10mm from the top of the line. This point will be point B
  5. Draw a line between point A and point B.
  6. Cut along all of the solid lines, not the dotted lines, using a circular saw.
  7. Set your side pieces aside.

Step 2: Make the Ramp

  1. Get your 500mm x 840mm piece of ply and clamp it to your workbench so that one of the 500mm sides overhangs the workbench.
  2. Using your planer, cut a 25-degree chamfer in the overhanging edge.
  3. Set your ramp aside.

Step 3: Screw It All Together

  1. Screw the two side pieces together, using the 6 pieces of 70mm x 35mm construction pine that are 467mm long, according to the diagram and images. You can use as many screws you want at this stage, but I recommend 6 screws per piece of wood, 3 on each end.
  2. Screw the top on by placing it on the assembled frame and lining it up flush with the ground, and then screwing into the pieces of pine, remembering to counter-sink your screw holes.

Step 4: Done!

Your ramp is now done, ready for tonnes of fun, and probably a few scrapes and bruises along the way!
