Free pump track build training!
« on: February 14, 2012, 11:01:03 AM »
Hi All, we need volunteers to help Alex build a pump track at The Fairgrounds on Thursday this week. It's possible we could be ready as early as Weds evening. More details to follow.
Thanks, Griff.

I'll be up there for the "free pump track building class"...I'm bringing my bike too and as a service to the mtb community I'll put on a "free class" on how to rip!

I'm heading to the fairgrounds this afternoon to orchestrate the dirt placement.  They are nice enough to provide us with a big loader (w operator) to bring dirt from a nearby barn.  Even with the big machine it takes many hours and multiple trips to give us enough dirt for even a basic track.

Here is the loader (photos from last year):


Last year they tried to help us with the rough shaping with a skid loader.  Unfortunately it easily got stuck in the loose dirt piles.



We were left with this to be shaped by hand:



It took a lot of labor hours by many people to carve out the most basic track last year:



I'm not sure what we are going to be able to do exactly but i did sketch out a few ideas:

Based on the amount of dirt and time it took to do even the most basic track last year, I'm guessing we'll be doing something very basic this year.  Probably a kidney or an oval shape.  The space is 40x100 but after accounting for our booth, bike staging and buffer zone the track area is probably more like 30'x60'.

On of the most important considerations is that this is intended and will be most used by kids, many with limited bike skills.  We need to keep the rollers and berms somewhat tame (at least for the main line) and have everything tapered to the floor along the sides - no abrupt edges to fall from.  Ideally, we'll be able to create a mellow inner line with a more aggressive outer line.  I want this to be fun for the volunteers as well!

For those offering to help tomorrow, thank you, we will need all the help we can get.  Griff will be coordinating volunteers and keeping this thread updated.  We won't know the exact times and directions until after we get a better sense of the logistics this afternoon.

If you're coming to help please do a little online research on pump tracks.  It's not too complicated but it will require quite a bit of shaping to make things really pop.  The "training" Griff refers to in the title of this thread is a bit misleading.  This will be a group learning and experimentation exercise.  Hopefully we can transfer what we learn from this to a permanent track in one of our parks this summer.

If you are still in need of volunteers I'd love an excuse to get out of the office and get dirty.  I have been wanting to make it over and meet you all too and thought this would be a good opportunity.  Let me know if you still need competent bodies, both machine and hand tools/shaping, and where to be when. 


My email is andy.williamson@imba.com

I'm there... I'll keep an eye open for updates.
My girls would probably love to help too.

We're here now unloading dirt and Alex is moving it around. Tomorrow be here around 09:00 in the rear of the Champions Hall. Just drive in and park near the grandstand. All help appreciated tomorrow. Today we'll just be rough shaping and anyone is welcome to come take a look but we're not sure how much work there'll be this afternoon and evening. We will need a hose to damp down the dirt around 50 feet long if anyone has got one. All handtools are here.

I can bring some hose, if it is still needed.  Not sure if it is 50 feet or not, but probably close.
Thanks,
Lee J.

I will be there in the morning.  Do I need to bring anything in particular other than work gloves?
