How To Build A Grind Box For Skateboard?

Here are the necessary steps in the method to build the grind boxes for skateboard

  • Prepare materials needed
  • Cutting the legs
  • Put the frame together
  • Add the top
  • Paint grind box
  • Install the angle iron

Step 1: Prepare

Fortunately, all the components needed for making grind boxes are around your house. The preparation step may be simple.


  • 2 x 4” wood board
  • Plywood
  • Angle iron
  • Screws


  • Driver
  • Drill
  • Saw
  • Pencil
  • Tape measure

Step 2: Cut the legs

Start your project by cutting the legs on one of your 2 x 4s. You have to take a measurement of 9″ on the 2 x 4 to get the height you’ll want for the legs. 

The grind box needs six 9-inch legs. After finishing the cutting job, you can move to the frame part.

Step 3: Put the frame together

To build the frame, align two 2 x 4s in a straight line. Then, put a leg between them at each end. 

Next, you need to pre-drill two holes through the 2 x 4. Insert the screws to keep the wood board in place. This step needs repetition. You have to pre-drill all the 2 x 4 pieces.

Each end of the 2 x 4 now has two legs. This is where your frame’s bottom would be. It’s time to put the frame’s top element together.

Pre-drill and screw other 2 x 4 pieces to the top with the same method as before.

Now, you may finish the frame with the addition of the middle leg. To begin, measure the midpoint of your frame. Then, at both ends, pre-drill, then screw the middle leg into the center of the frame. Half of the frame is now complete. For the next frame, repeat the same steps above.

After you have screwed all the legs, you’ll have two similar frames that are waiting for the plywood to be placed on top.

Step 4: Add the top

The plywood should be 6 feet in length and 16″ in width. After cutting, lay it on the frame. You need to line the plywood up at both ends.


Start nailing the plywood to the frame in all the corners, as well as the center legs. If necessary, use more screws.

The next step is adding braces at the base of the frame. The two braces need to be 16″ long.

After trimming the braces, put them on the bottom of the frame at each end. The frame will be sturdy and solid after you insert the braces.

Step 5: Paint the grind box

Now your work has grind boxes form. This step is not compulsory. However, the painting coat serves as a weather barrier. Painting can also make your box more stunning. You should try it. 

You may apply whatever paint you have on hand or go to the hardware shop to get some.

Painting the grind boxes is not compulsory but advisable

Step 6: Install the angle iron

In the last stage, you need to trim the angle iron to fit exactly on the ledge. This procedure can be hazardous since it creates a lot of sparks. Ensure you’re outside and far from anything combustible.

Wherever you buy the angle iron, you may have it cut to size.T his approach will save you money and time.

You need to pre-drill the screw holes. After that, secure the angle iron to the ledge. Create a pilot hole with a smaller drill bit. 

Ensure you don’t drill through the iron with the bigger drill bit. The goal is to merely countersink the screw flush with the iron. It ensures that skateboard trucks may grind over without getting hooked up on the screw head.

Next, drill three screw holes on the top side of the angle iron and two on the side of the angle iron. 

Set the iron on the ledge. Make sure it’s flush on both ends. The angle iron must be the last to screw.

After all the screwing tasks are done, you’ll have a DIY grind box.
