On the 2005 team I mostly wrenched on crap. Since I was working in a machine shop at the time and had some experience there, I got to do a bit of fabrication for the car. Wound up spending a good bit of time getting to know the ins and outs of the chassis, and went to competition. Tough break for our can-do-it-all team captain, problem in enduro and a low finish (after the 2004 team's best-place 23rd).
As a junior on the 2006 team I decided to get more involved and did a design-related independent study. The previous upright design took one or two guys about a week each to CNC machine on campus. Having them outsourced took a couple days each and $1500 for a pair. I thought this was ridiculous. I designed a new, modular upright with "DFM at all costs" as a goal. Pulled some weight out and reduced to fabrication time to probably 3 hours each. There were some wheel bearing "issues" and a lot of joint stiffness compliance, but it just barely held through competition and we held a school-best 22nd place finish.
2007 rolled around and I found myself as one of the co-captains. We started with a budget of -$5000 (that is a negative sign) and 9 senior design members, down from 11 in '06 and 13 in '05. Once again I designed the wheel assembly, and once again had compliance issues. I also CNC machined the vast majority of complex parts on the car, welded the frame, and did some of the DAQ wiring. This had been 3 people's work a few years previous. Bad decision. Needless to say I was pretty busy and did a pretty poor job as a project manager. Got the car done, got to competition, but had a driveshaft "issue" in enduro. Still, I learned a lot, and the judges liked some of the tire data work I had done.
Afterwards I traded in beautiful, sunny, no-humidity Boulder, CO for grey, rainy Akron, OH. Why? Great question. I'm still not sure that was a wise decision. But in any event I'm here, working as a tire/vehicle dynamics engineer, and I feel like building another racecar. Which brings me to my next topic...

Looks pretty bad ass. I hope you get to build it.
