Building Jumps.
« on: May 23, 2007, 03:48:52 PM »
I just moved into my new house and was hoping to build a Pump track in the back yard before we put down sod. Not surprisingly, my parents didn't exactly jump at the idea. So I'm just going to do a jump or 2. I was thinking that with this florida sand that I should put some logs in the center as filler. Does anyone have any or tricks on what I should make sure to do... or not do?

I'm not a jumper, but I would think that building a ramp out of wood and plywood is the way to go. My knowledge is all based on the Napolean Dynamite movie, so take it for what it's worth.  I remember they were skyin' pretty good in that movie.   ;D

Check out the May issue of Mountain Bike Action.  The had a section in the back about bruilding jumps/Ramps.  Best bet don't use sand, It won't stick well and erodes easily.  Go with a clay mix.  I hope that helps.

It would seem to me that you could do a lot of work with sandbags as the basic filler of the jump, and then only have to hard-pack the surface of the feature.

You could also build a rather light-weight wooden frame, with wooden battens about where the surface would be. Sand-bag under/around it for support, then lay the clay down between and over the battens. This should help keep erosion to a minimum and would let you know when the surface needs more covering (the battens would begin showing).
We see the world not as it is, but as we are.

I started working on it. Im starting off pretty small as I can get alot of speed going up the drive way. Im just using the soil right now and packing it down alot. I might go wooden though. One of the good things about sand is that it doesn't hurt to land on.
