Fast. Strong. Beautiful. Unique.
Did I say Fast? Extremely Fast!
How do you steer? By weight shifting.
How do you brake? You don't.
Brakes were invented by cowards.
This Extreme project is Extremely suited for the Extreme contest because your whole life would go Extremely fast before your eyes even if you close them bombing down that Extremely steep hill.
You can't buy anything like this but it's Extremely cheap and easy to build yourself.
Step 1: Parts & Materials
This particular sled is comfortable for two adults or one adult with two kids but building technology is easily adaptable for smaller or bigger designs. For the smaller and lighter one person sled two support arches is sufficient. Start designing with the skies. Shorter downhill skies are harder to find but cutting the long ones would probably compromise it's structural strength and shape.
You will need:
Pair of used downhill skies you can buy cheap at second hand store. Take off all bindings.
Piece of plywood for the seat. I used cushioned seat from the old automotive creeper. Be creative.
1-1/4" Gray PVC 90deg Elbow, Schedule 80 - 3 pc (Look for electrical conduit)
1-1/4" PVC plug - 6 pc (look in plumbing, not all hardware stores have them)
1-1/2 x 1-1/2 x 1/16 thick Aluminum Angle - 6" long - 6 pc
Various nuts and bolts.
