ya know those fold out tables. i think that wood work, just get a 4'x4' piece of plywood and put those fold out legs on it, then get some hinges and put another piece of plywood off the side for a ramp.
dude hes asian, asians think about this fucked up shit
don't worry im not racist i have a colored tv
I think the best thing to do would to be to make like an inrun or whatever, jumps are pretty simple to make for rails. You really dont need that much height out of them so it shouldnt take long to throw one together.
For portable, basically what I have done is just take a fairly long piece of plywood that is long enough to ski down and lean it against the top of a car or the tailgate of a truck. Nothing to high-tech but it does thr trick.
A couple years ago my buddies and I built a uni-booter out of ply-wood...real simple. Take a 4'x6' (1/2 in. thick works good) sheet of ply wood and put thumb tacks in it in the path you want the elevation of the ramp to follow then wrap some string around the tacks and trace it so you get a uniform line. Cut along the line. Trace that for the other side. Then get some 2x4s and make cross beams all up and down the ramp and some on the bottom and front for support. Then take some thinner ply wood, prolly 1/4 in thick and layer it on the top for the actual ramp. Screw it into the side pieces. This shit has sat outside for 4 winters and never rotted...guess that comes with treated wood though. MID-WEST ROCKS IT WITH FAKE SNOW AND WOODEN JUMPS!
Some people only see that I'm white ignoring skill cause I stand out like a green hat with an orange bill...
