So my school is having a run-what-you-brung type soap box derby race in a couple weeks. Since I'm home on spring break this week a friend and I decided to throw something together.
The only rules they set as far as design was mechanical steering and stopping capability, gravity power only.
We're going for a late '50s Front Engine Dragster look.
Started by lopping the front suspension and steering off an old golf kart with the gas axe. Cut a big chunk of oilfield pipe in half, sleeved it onto the stub, and arc welded it up.
Chopped up a stick of holey square tube (sign post) for various crossmembers. Also made some adapters from angle iron to mount 20" bmx wheels and tires to the golf kart spindles. We also welded on a school chair we procured during our last year in HS shop class.
He had some S10 wheels and tires laying around, so tomorrow when we take in scrap we're going to pick up a pair of front spindles and hubs, and one rotor and caliper from a 2WD S10/Sonoma. We're going to run that caliper off a motorcycle/atv master cylinder, on a hand control. Should provide plenty stout stopping power.
Yeah, it's a little janky right now, but we've got a little more refinement in store, and it'll get some attention from a grinder and a little paint before it's done.
