Back on my old website I had years of content posted but I tore it all down and am now trying to slowly bring some of it back to the new site. One of those is the old skateboard halfpipe I built in my backyard. I built it out of (9) 4X8 sections and bolted them all together. You can see the full build process and picture gallery here. I spent more time researching the project than I did building it. It took about 3 full weekends to build it. We used it for about 3 years and then sold it when we decided to build a retaining wall and pour a cement patio.
