Land of Ladders

This Video (http://www.youtube.com/watch?v=p62Hxd5-JuE) appears to have been around for a while, but it is still worth watching. Some of the sections are just outlandish!

That would be the end result if Busch Gardens and Home Depot were forced to propagate. Looks like they resorted to rippin' out Mom and Dad's kitchen cabinets for wood there at the end.

I think you've officially gone ladder crazy, Pie-writ!

Thats frickin awesome. I wish I had a backyard to build stuff in.

[Brizn]

Or even a front or side yard for that matter. Spkg of which.. Pirate, you should build more stuff in your backyard.. make a handful of ladders and boxes and stuff that you can reconfigure every so often!

Here's another link to footage of that yard, plus more sick MTB stunts.

Ouch! Check out the impact + bounce starting at 4:28.

If you want to spend a couple of weeks down in Georgia I've got a yard you can build it in. ;-)

Wow... Uncle Jimmi is over-the-TOP!

I think the drive-thru chick makes the whole video. :D

Yeah, I've thought about that... My building skills aren't all that great yet, though. What I'd really like to do is add some swoopy ups and downs... Almost like an elevated pump course. I just don't know how to make them smooth and curvy yet. Got any ideas?

I helped a friend build a half pipe in his warehouse many years ago. He had a very good method for conforming wood to the shapes that he wanted.

He used plywood to cut out the cross section shape of the curve. Then, he screwed 2x4s into the plywood at the points where he would screw the sheeting into the cross section. Two layers of plywood and he was done.

How is that relevant? I think that the cross sectional forms would come in really handy for you. With a jig saw, you can create whatever curve you want in cross section, then you can use 2x4s as the anchor pieces, and put whatever material you want to form the riding surface so it is substantial enough to ride on.

If that makes no sense, I'll draw a picture, or get SketchUp working to show you what I'm talking about.

Maybe a field trip to Ray's is in order?

You're talking about using the 2x4s as ribs, which sounds like a good idea for the vertical changes. (bikermiker and I built a few half pipes, quarter pipes, launch ramps and other assorted skate ramps back in the day). But the part I'm having trouble figuring out is how you make the transitions from right to left, etc. with any kind of banking. The plywood and 2x4s will only work (as in remain in one piece) if everything is squared up. Once you start slanting the plywood, things get more complicated. Especially if you're riding at high speed over it. It better be over built.

punga!

I think this is a conversation best had w/ pencil and paper in hand. I'm thinking that the plywood gives a fast way to create the form, then cross bracing is produced to provide structure. All the structure ends up squared and diagonally braced.

There are probably better ways to do more complicated transitions. But in terms of creating curved shapes, starting with a solid sheet of plywood and cutting out the shape of the curve that is desired it much easier than trying to build a bunch of 2x4s into the shape of the desired curve.
