How To Build A Halfpipe?

By:


Before constructing your halfpipe you should figure out the full dimensions at the onset stage, that is, the length and width of the structure. A larger ramp would be more ideal for skaters who prefer a bit of challenge and/or who are very experienced. Building a halfpipe is not excruciatingly difficult, but will take a bit of carpentry know-how.

Required Materials

1/4 Plywood
3/4 Plywood

Required Tools

Jigsaw
Nail
Wood Glue
Wood Screws
Roller
Paint Tray
Carriage Bolts

Instructions

1.Begin by constructing a life-sized template of the quarterpipe. You will have to utilize this as a guide while constructing your halfpipe. Essentially you will be using this to make sure that all your end supports are identical in size. You may use 1/4 plywood to make your template.

2.Attach the pieces that you have formed using duct tape or if you feel like being a little bit more exact, use a bit of 3/4 ply to make scab plates that you then can attach together with normal wood screws.

3.Cut your ply in half along the vertical path, you will be getting more out of the wood by doing this.

4.Cut off a section of about 2 feet from one of your pieces of ply and join/scab it to the large piece that has been left uncut. By doing this you should now have a 2ft by 10ft rectangular base.

5.Then you will need to build a 5 foot square that you will then jin to your rectangular structure, it will look like a very large boot when you are done.

6.Mark out your radius utilizing your nail as a pivot. The radius should go from the top corner to the lower corner that falls just beneath the nail.

7.Utilizing a jigsaw cut out the radius for your template.

8.Now you can use your quarterpipe to create your end panels. Building your end panels by using two layers of 3/4 inch plywood. You will need to laminate the two together to make certain that it remains stable while in use. This can easily be done by using wood glue to join them together. Place some wood glue in a paint tray and get a roller and put a thin layer of one glue on the surface to be laminated. Place the top layer over this layer and ensure that the edges are flushed. Allow this to set overnight. When it has dried you may use your template to build the end panels. Cut these out using a jigsaw.

9.Again you will use your template, this time to create intermediate supports. Make scab plates from 3/4 ply joined together, make sure that the scab plates are no less than two inches away from the edges.

10.Cut a few 2 by 4s into about 3feet by 9 inches in length. Ensure they are cut equally.

11.These 2 by 4s can then be laid on your structure to create the flooring. Nail these in properly with a hammer and a few wood nails.

12.The most important part of the process is creating your support frame. This will allow the halfpipe to support your weight. You may choose to create additional support by anchoring your structure to a building. When you have figured the type of framing you will utilize, anchor this to the almost complete structure utilizing carriage bolts.

13.Then construct your riding surface using 3/8 inch cdx ply for greater flexibility. Run the layers in the same direction making sure that the end joints are set up unevenly for additional strength. Screw these layers unto your flooring once you have set them up correctly.

Tips and Warnings

You can actually get your ground more level by shimming beneath the framing. However, if you are doing this make sure it is done properly as this can result in a unstable overall structure.

Your halfpipe should not shaky, if this happens you may need to anchor it with a bit of concrete. You may do this by placing your quarter pipes into the ground for extra stability.
