Soap Box Derby Racer

So if you’ve ever read this blog before or met any of us, you already know that if it has wheels, we dig it. Better still, we’d probably like to rebuild it, change it or even make it from scratch. Not that motorcycles ever get boring, but it’s nice to mix it up from time to time.

We’re having a father’s day soap box derby on our block this weekend so Casey and I decided we should put something together for it. We talked about it sporadically over the last few weeks but didn’t actually get anything done. Last week, when we intended to build it, we sat around the shop sidewalk drinking beer with our friends and neighbors all night rather than actually accomplish anything. This was apparently much needed as we’ve all been working our asses off at our jobs lately and just didn’t have it in us to exert any effort on a project.

This left us with four days remaining to come up with something, sketch it out and build it. We started Tuesday night and ended up staying until 2am. We didn’t want to leave until we had a rolling chassis. I think that was an important decision, otherwise it might never have gotten finished.

Our friend Al up the street donated an old beater bicycle to the cause and I snatched the wheels off my old Stump Jumper which hasn’t been ridden in years. Using a single length of square tube we had laying around, we created the entire frame. The bicycle was cut up to yield three forks: The original front fork, the rear seat stays serving as a pair and finally, the rear chain stays with the drop out tabs serving as a pair. We notched the square pipe after marking our angles, bent it upward into place and welded it shut. We flattened out the notches we removed to use as gussets on those joints.

Last night we added handlebars, a deck, a brake and welded a cantilevered seat the rear section so that two people could ride it. As this race is for neighborhood kids, we set it up so kids could sit on the deck with the adult on the seat doing the steering and braking. Not shown is a foot rest/wheel guard on the front to keep small feet out of the front tire.

We had a great time making this together and look forward to running it this Sunday.

Finished product, less the foot rest we added at the very end.

Gotta sign your work, right?

Bottom bracket and chain stays now serve as rear fork.

Seat stays serving as other rear fork. A little "smash & weld" going on to make it fit.

Frankenstein neck tube. Strong like bull!

Rolling chassis at the end of the first night. Still figuring out seating arrangement.
