blue print for a spiral

[xtrememtbkr]

do any of you have a diagram of a spiral? we
have to submit a plan for every thing we build to at our
bike park to a committee and it would be great if any one could
help out.

by spiral you mean?

Like the thing Matt Hunter goes down in, In his UFC video......Kinda like a spiral staircase but northe shore ladder style :thepimp:

omg i was thinking about a huge spiral thing thats like 50 feet high, pretty wide so you could get some speed and control and you just fly down, around......like a constant berm:) you could put the entrance at the top of a small cliff face, go down and exit below..........that would be so nice....that would probably get you in a big vid (like that hampster wheel, or cowans loop did)


wow......loops, hampsterwheels, spirals.....haha good stuff:D

I don't think too many have been built, But I don't think the plans would be that hard to draft up yourself...

[sir HUCK-A-LOT]

basically the concept is getting a good center piece.
i dunno what matt hunters was built around but the center piece is the key.
imagine building it around a tree.....then you basically have runs going outward from the tree at slightly different levels to create the downhill spiral.

even if you dont use a tree if you can get some solid wood that is deep into the ground then you have a good center area and somthing stable to build off of.

it would actually be really easy using a tree lol

[D|-| D@|\|]

it would be a like twirly slide:lol:YAY!:rolleyes:

We have one of those, but the guy was drunk when he built it, so it's not the right angles to ride :(

ahem...

BAHAHAHAHA

Sorry man...this is the first thing that's made me chuckle out loud in a while. *still snickering*

The woodlot has one...woodlot gold I believe. Big stump, make sure it's pretty tall at the top since you need enough space to make it under without hitting your head. More than one turn would require a LARGE main post.
