Introduction: Easy DIY BMX Jump
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.
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
- 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.
- 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
- From point A, use a set square to draw a dotted line across the ply.
- Mesure a point 10mm from the top of the line. This point will be point B
- Draw a line between point A and point B.
- Cut along all of the solid lines, not the dotted lines, using a circular saw.
- Set your side pieces aside.
Step 2: Make the Ramp
- Get your 500mm x 840mm piece of ply and clamp it to your workbench so that one of the 500mm sides overhangs the workbench.
- Using your planer, cut a 25-degree chamfer in the overhanging edge.
- Set your ramp aside.
Step 3: Screw It All Together
- 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.
- 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!
