How to Build a Quarter Pipe

How to Build a Quarter Pipe Ramp for Skateboarding?

So you want to learn how to build a quarter pipe ramp so you can practice at home? The good news is you can make a quarter pipe using simple tools and materials. It is easier and less costly to build compared to half pipes plus, you can move them around to anywhere you want to practice. But before we begin with a simple tutorial, consider the area where you’ll be using the quarter pipe ramp. It should be even, clear, and free from any obstructions. When you’ve found the right spot for your DIY ramp, start gathering your project materials. A ramp constructed properly will give you years of use.

Things You Need to Build a Quarter Pipe Ramp

You’ll need the following to build a quarter pipe ramp at home:

  • Pressure treated lumber – two 8 feet 2x8mm, one 8 feet 4×4, eleven 8 feet 2×6, eight 8 feet 2×4 
  • String and pencil – you need 6 ½ feet of string
  • Masonite – one 4×8 foot at ¼-inch thickness
  • Plywood sheets – four 4×8 ¾-inch, two 4×8 3/8-inch
  • Measuring Tape
  • Metal pipe – one 8 feet 1.5 inches
  • Electric jigsaw and drill
  • Screws – one box of 2 ¼-inch ramp putting screws
  • Metal drill bit – 11/64-inch and 21/64-inch metal drill bit
  • Thick sheet metal – this is optional – one 6×8 sheet metal, you may have this pre-made from steel fabrication shops
  • Safety gear –use safety goggles, gloves, and mask. Work on a fairly level surface.

Instructions

Cut the sides of the ramp

Place your 4×8 piece of plywood at ¾-inch on the ground and create a line down the plywood middle to cut the piece equally. Then, use the tape measure to get 6.5 feet from its top to the other side and across. Mark a point at 2.5 feet beyond the plywood sheet end.

Place a 6.5-foot piece of string to the spot with a small screw or nail. From the other end of the string, tie a pencil. Keep your string strong and tight and use your pencil to create a long arc on the surface of the plywood from one edge to another.

Use an electric jigsaw to cut the sides from the drawn lines. first, cut a semicircle at the arc and then, cut from the centerline to create identical pieces. 

Assemble the sides of the ramp and the curved side

It’s time to cut 8 pieces of 2×4 lumber to 94 ½ inches long. The lumber plus the two plywood pieces will make 8 feet across when these are assembled. Cut three lengths of 2×6 lumber pieces to make 94 ½ inches long.

Put a 2×4 piece of lumber for every 10 inches across the transition radius of the ramp in between two sides and then connect the ends to the plywood using screws. Take note that the top part of the board will be flushed with the top ends of the sides and will be perpendicular to the ground. 

The bottom part of the board will be parallel from the ground. All the remaining boards will be angled to make them perpendicular to the transition curve. Put the 2×6 wooden boards in between the back of your cut sides from the bottom, middle part, and the top. User screws to connect these pieces.

Attach the coping and threshold material

Create four evenly-spaced holes on the 8×5 length metal pipe using a 21/64-inch metal bit. Never drill through the pipe! Create 4 smaller-sized holes through the other side of the metal pipe with an 11/64-inch metal bit. The bit must be placed into the large holes that were previously drilled and make smaller holes to the other part of the metal pipe. 

Attach the coping at the top part of the quarter pipe of the transition frame using pre-drilled large holes. Install 4 screws through the coping using the large and smaller drill holes through the wood so you can secure it. Take note that the screw heads must be large to catch the smaller hole from the other side of the wood. 

Install the transitions

Start from the top far left of your quarter pipe’s frame. Screw a 4×8 foot sheet with 3/8 inches plywood into every 2×4 piece of lumber. Work your way to the bottom part of the pipe. 

Install another 4×8 sheet of 3/8-inch plywood to the piece that you installed. Screw this on the 2×4. Cut another piece of 4×8 plywood that you cut from the top part of the plywood at the left part of the ramp.

Attach the 2×8-foot plywood piece that you cut from the top part of the plywood from the edge of the ramp. This layer will enhance the stability of your ramp. Attach another 4×8-foot sheet with 3/8-inch plywood right beside the 2×8-foot piece. 

Add the second 2×8-foot plywood sheet to your full piece to complete the ramp riding surface portion. Install the first 4×8-foot ¼-inch sheet Masonite piece on the second sheet of plywood. Add another 4×8-foot Masonite sheet right next to your first layer.

Now, it’s time to make the transition. Use a sheet metal piece 6 inches x 8 feet; screw this to the Masonite from the bottom part of the ramp. 

Construct the ramp platform

Use 12 pieces of 2×6 lumber that’s 4 feet long. Attach another 4-foot board from the side to the 2×6 from the top to the end of the ramp transition. Add another 4-foot board and install it from the other end of the ramp. This will complete the platform.

Cut 2×8 –mm long lumber into 8 feet. Screw this on the 4-foot boards at 2×6. This completes the back part of the platform. Make two 4-foot pieces from your 8-foot 4×4. Screw this in place inside the back part of the platform and attach these to your 2×8 and 2×6 boards. This will improve the support of the platform.

Next, measure 1-foot increments from the back of the 2×8 frame. Attach 7 of the 4-foot 2×6 boards from the 1-foot measurements on the 2×8  pieces. These will be the support for your ramp platform.

Cut your 2×8 lumber into 8 feet and attach these with screws from the bottom of your two 4×4 wood. Finally, screw the 4×8 plywood at ¾ – inch on the frame.
