more pics, mostly welding.
first off, our side body panels, in fiberglass. we molded this around our frame tubes and will be pulling a carbon fiber part off of this.
this years brake setup. just overall lighter, cleaner, and more easily maintained than last year's.
our engine mount. has about 3/4 inch or so adjustability for belt tensioning. all of the bracing not only holds the engine but also stiffens up those rear lower frame tubes.
now the welding pics. these welds were done with an old linde welding machine, 1/8" tungsten, and around hundred thousandths filler rod or less. not really sure on the size, but it's really small. all metal is 4130 chromoly
first is our tow hitch. this part is really visible, so i tried to lay down as good of a bead as i could. the tube it is welded to is .028" and the hitch was made with .032" sheet
fire extinguisher mount
a weld on the roll hoop bracing. this is .028" to .065" inch i think so the bead is a little wider.
some bench welds. this is .75 .028" thick tube. just messing around.
penetration

dang, no offense but I'd be on the formula team, that would be sweet!
Looking good though. Looks like too much fun. What degree are you working on? Mechanical Engineering?

^penetration?! haha!!!
clean work. do you guys have special people to do special jobs or does everyone sort of pitch in? at what point is it decided you need a new frame/hardware?
i remember doing stuff like this in middle school tech ed. would always get A's and beat the hell out of everyone else. and my co2 car flew into the ceiling across the room instead of its track and the egg was unscathed and the frowning teacher told me i was lucky. always dreamed of building these kinds of things.
i just finished watching beyond thunderdome. i was wondering what this thread reminded me of.

i planned to be on the formula team before i joined, but was assigned to the baja team b/c they were short on members.
glad i did. i would have never got to the point where people on both baja and formula ask my opinion or for help if i didn't get thrown right into the learning curve by being on short staffed baja team. most of the people on the formula team don't get to drive, and i've driven it before. we can drive the baja car whenever we want.
i'm actually a physical sciences major with my main area of concentration in mechanical engineering and secondaries in math and physics. i would be just a regular mech engineer if i wasn't screwed over with transfer stuff and the limited enrollment engineering department.
hkc, we build a new frame every year. it's pretty much required that you build a new car for each year's competitions. if you don't you have to show all these changes and it is a class and learning fabrication skills is part of that. with a new frame comes a big order from fastenal for all of our hardware, mostly 1/4-20 or 3/8-24.
i do just about everything seeing as how i am one of two people on a 8 person team that's already been to a competition. the only thing i haven't really done much with is testing, which the other guy from last year took care of. everyone else pretty much chips in where they can and with what they are interested in. we also have a few "mentors" for the baja and formula team that are students that graduated a few years back and really know what they are doing. they are the only ones that really know how to do the cnc work, but hopefully i will find some time to learn more of that too.
