Jump Frame

[BillanookRun]

Ok so i did a search and didn't find exactly wat i was looking for. So i decided to ask here and see what you guys think.

In an effort to minimise dirt wasting in my dirtjumps i was thinking about making a frame/mold for an upramp. The basic jist of it was that i would put a backing and sides on like a wooden upramp but leave the face open and the top. My question is do you think that if you just put all the dirt inside a frame like that and keep it nice and compacted and then once you've left filled it to the top, will you be able to pull the "mold" off and there will be a perfect square flat smooth upramp to use as you wish or do you think it will just crumble?

you will probably know, but the dirt will be cheaper then the wood in the end. i would have a look on a of the mtb dvds and just look at some of the down ramps as a few have a wooden frame.

i have thaught about doing this my self. i think that if you use very wet soil and pour it is like concrete it will work. you would then have to wait for it to set for you to shape it.

You could also use a dryer mixture and compact as you go. give it a go and see what hapens.

Hey brad where you thinking of using them on Ya mums snail trail?
I reckon it might work mainly if you made the frame sort of diagonal instead of vertical so its got something to fall back on.
Go brad

ive recently done sort of the same thing with the kicker of my four pack in my backyard but with bricks.... it seems to be fine so far although i havent hit it because it has no down ramp for the second. I used bricks to support the back of the kicker and then gradually built it up and as it got steep i made a muddy sort of mixture in the wheel barrow and poured it on to keep it steep and not crumble. ill let you know how it goes when ive finished the dr.
