Crazy Question, How much dirt would you need to build a small pump track? My berms will be 14ft. in diameter about 24"-28" in height. I am going to use some of the sod I am cutting up to reinforce the berms. The track will have 4 rollers total, each about 14" in height and 8' long. I guess I am aiming this question at 'Spence'.

Tony- Mani built a pump track in his yard with a sod cutter, rolled sod, and then the dirt in between with minimal extra dirt. You can contact him at the mtb site (www.ride-it.net) and go check it out, it's one of the funnest ones I've ridden

Tony,

Based on your description you will need approximately 60 yards of dirt (about 6 dump truck loads) to do the job. You might be able to get away with 50 yards. The sod will need to be capped pretty thick so you dont get that spongy feel. Rollers with 8' spacing and 14" tall is pretty tight, you might want to push it out to at least 10' to 12' peak to peak.

Here is a picture of the pump track I designed for Bernie U by his house in Cali'.


Just some ideas,

Now I'm home sick Steve. How did you like the sunny skies of Ridgecrest, Ca.? I graduated HS 22 miles East of Ridgecrest in Trona. I believe that view is from "College Heights"??? Does Bernie U live up by Cerro Coso Community College?

Steve-

WOW, that is a lot of earth! I am having 3 yds delivered friday to start. The dirt is top soil, screened, and packable. It's $21 a yrd. How does that sound for price? I have a little ebook from LeeLikesBikes.com that discusses the building of pump tracks, so hopefully that will help. That track you designed looks amazing! I wish I had that much property, I would do that in a heartbeat. What are the demensions of the rollers? I will only have two down each straight, a total of 21ft from berm-to-berm. Say, how much would you charge for a little track? Call me: 560-8589. I will have everything ready by this friday to start building.
