Building your own DIY skate ramps is not only fun but empowering. Get some friends together and get to building.
This grind box is 240cm(8′) long, 30cm(1′) high and 40cm(1′-3 3/4″) wide. These are the perfect dimensions for all your grind and slide combos. You can, of course, adjust the dimensions to suit your needs.
MATERIAL CUTTING LIST
WHERE TO BUY YOUR MATERIALS
You can find most of the wood, steel, and hardware that you will need at your local hardware store. If you based in South Africa, then the franchise Builders Warehouse has everything you need. Or if you don’t have a buck to spend, embrace the spirit of DIY and be resourceful. Old wood pallets make great framing material for the box.
Step 1: PREPARATION
Follow the cutting list above and gather all your materials together. Having some power tools like a drill and jigsaw make life easier. But they are not essential. You can get away with a good old hand saw and hammer. Just take note that screws do result in a more solid box that can be taken apart easily as apposed to nails which are a bit more permanent. Make sure you get screws or nails that are longer than 5cm to get a sold fasten on the wood. Course drywall screws are a great option.
Step 2: FRAMING THE BOTTOM
Let’s build the bottom of the box to look like this. You will use two 3.8×7.6’s at 240cm for the sides and three of the 36cm pieces for the framing.
When attaching the 36cm pieces, make sure to pre-drill the hole before inserting the screw to prevent splitting. Then insert two screws to attach each side of the timber.
Step 3: FRAMING THE TOP
Next, frame the top of the grind ledge to look like this. Use the last two of the 3.8×7.6’s at 240cm for the sides and nine of the 36cm pieces placed every 30cm on center as shown.
Step 4: ATTACHING THE SIDES
Attach the six pieces that are 30cm in length to the bottom of the box like shown here. Put four screws in each piece, two through each side.
Step 5: ATTACHING THE TOP
Place the top on the newly attached sides. This is much easier if you flip the bottom over or lay it on its side. Put four screws in each just like the bottom. Make sure the ledge is square. If you don’t the box will rock on the ground like a wobbly table.
Step 6: ATTACHING THE PLYWOOD
You’re done framing the box. Now you want to attach the plywood as shown in the picture.
Step 7: ATTACHING THE COPING
Place the angle iron on the edge of box like shown. Drill a 3/16″ hole on each end on both sides where shown. The top and bottom dimensions are offset so the screws won’t hit each other. On a box this length you need to place a couple more screws about 100cm apart on each side.
Once drilled, countersink each by using the 3/8″ drill bit to drill down just enough so the screw heads are flush with the coping. This will keep your trucks and board from hitting them when you grind or slide.
And that is all that goes into making a DIY Grind box. I hope you enjoyed building it, but most importantly I hope you enjoy skating it. Hit me up at josh@apexactionsports if have any questions.
