Me and my dad have been building obstacles like banks and stairs out of wood and we don't really have problems building those obstacles but we cant think of a way of how to build a quarter pipe or tranny obstacle. If any one has any ideas please tell me. thank you.

You can use veneer and bend it

Ok thanks that makes sense.

Use flexible plywood. It's like a thick venner, mesh, thin veneer, mesh then thck veneer. It's the same stuff BRR uses, I nicked some from tech and i'm gonna make some soon

Thanks this will really help.

I'm sure you could also add more then just one piece of veneer? You could stack the plies like you would a fingerboard so it would be strong? I have no idea if it will work though.

Google Bending Plywood (Flexply, Wacky Wood and Wiggle wood) - this is the stuff you are after..

I made mine out of plywood and hardboard (masonite, I think it's called).  It's not the greatest, but it was very cheap to make and rides well.  Don't wet it too much, or you'll end up with a break in the ramp like mine.  I used a vice to put the three pieces of plywood together so I could make an even cut.  After a lot of sanding, it came out almost perfectly even.  Also, the drill was dying so I didn't get a chance to countersink the screws.
