I want to make a 270 degree berm from some wood. It's ex floorboards and i need to know how many boards (there 6" wide x 3ft) i'll need and the best radius for the berm. It's on an downhill slope which is about 35 degrees. :)

it's not 270, but here's a pic of a wood berm at The Colonnade in Seattle:


another one at Duthie Hill under construction:

Wait, you want to put it on a slope that's 35 degrees? That's extremely steep. The slopestyle courses I've ridden looked like they were about 6-10 degrees when measured from top to bottom. Also, almost all berms are on areas which are flat or near flat (see the pictures above).

Could you give us a better description of where you want to put this berm? How fast will you be going when you get to it? Do you want to enter with the fall line and then exit across the fall line? Is there a good downslope after the berm? What comes before the berm?

Something to consider with a 270 berm is that it's going to eat up a bunch of speed compared to a 90-180 berm. If you watch this video starting at about 50 seconds in, you'll see how much speed their berm eats up. These guys are absolutely hauling when the enter the berm, and are struggling to clear the next jump afterwards.

thanks for the photos they have given me some idea. Also the whole point of the berm is to eat up speed because were exiting the previous dirt berm gunning it. The hill is on a 16 degree slope as i measured (sorry). I want the riders to stay on the fall line and exit on it as you said. After the berm is a downward slope which is a bit steeper then the berms building site.

Thanks Guys

Sounds like you are going to have to make it pretty big since it is on the fall-line like that. Otherwise you would slam into it and go OTB.
