I want to build a quarter pipe that is 8 feet wide, 6 feet tall, and im not sure about the radius yet. but anyway I want to transition to be made from 2x4s.. or any board for that matter maybe 1x6 or something. Not from plywood though, just strait up boards like a deck.
I've seen it done quite a few times, for example:
Kicker but same concept:
And basicly every ramp in the slopestyle part of this video (second part),Gornaya Karusel MTB open on Vimeo
Now heres where I need help, I've built a quarter pipe before but this is a harder to figure out, since I think if it just had the 2x4s laid across two boards they would have to much play in the middle. Im not sure. But doing a third support in the middle would be a damn lot of playwood, like 4 sheets of the thick expensive stuff. SO im thinking maybe not use playwood for the side supports and use something like 2x4s such as in the second two pictures and the video.
Any help or ideas on building something like this?
