Hey, I talked a lot last season asking for advice about my backyard terrain park plans. Well, the first jib got built, and there is a couple more in the making. But over a 100$ worth of HDPE, so pretty stoked about that. Anyway, here's the rail.
It's about 3 1/2" wide on the top. When we were building it the braces looked like if you fell off your board might catch them and you would go flying, so we put a sheet of plywood over them and we are going to put like 20 coats of ultra glossy polyurethane on it too slicken it up. Should be pretty fun. Cost close to 90$ to build.
