I started fab about a week ago with the help of a few others.  We have less than 6 months to build test and tune this thing. 

Were using a water jet cut jig to hold suspension points and the base of the chassis in place.


















more to follow...

I'm just curious, what is the point of FSAE? To spend the most time building it, making the most intricate car, or winning the actual race?

I would presume they deduct if you arrived sporting fluxcore welds.

[Passenger]

I dig your table, Acorn?

[DSharp]

The point of FSAE is to develop better engineers.  I do it cause I love to build shit and i can waste time doing something other than class work.  I also learn a lot of shit in the process, and I get to use tools, programs, etc that I otherwise would never learn about. 

I don't know if they would let you race if your chassis was all boogered up with some RMHT style fluxcore.

yea that table is awesome.  I think its an acorn.

Do all the cars look different? I have all these posters from all our fsae sponsorships and none of them have that big hoop in the back.

The current and past cars for our FSAE team uses a pretty significant hoop although not as tall as that one appears to be.

I really need to make time to contribute. It could make the whole school experience a bit more interesting.

Im more interested in your guys motor program. So do you guys actually build the motors/design motor parts/flowbench etc

[DSharp]

yea this car is big.  We have big drivers too. At least half of our potential drivers are over 6' tall.

I'm going to need some U bends pretty soon for this header.  I'm going to build it once I have verified it on the dyno.


I got all the main tubes in the chassis in place today and started welding.





We have a engine dyno and a chassis dyno and some good CFD stuff.  This is our first car since the program ended in 2001, so we don't have as much as I would like.

[Foowee]

Is the rear of the chassis supposed to be a sort of passive suspension?  The square "X" in the back looks as if it's gonna allow a bit of movement independent of the front end...

[DSharp]

I didn't design the frame, I have been arguing to add tubes here cause I don't like it either.

Draw it up Engineering paper and use what ya learned in Dynamics and Statics and prove them wrong. 

(Assuming use already took Vector Mechanics, or Statics and Dynamics)

[mandrel-bends]

You guys seem to be pretty well equipped compared to most universities.

I might just add it in and be done with it.

We have had a baja program for a while, and a few failed attempts at a formula car recently, so we have a lot of cool stuff, but there is only about 5 people who work on the project..... so my grades really suck.  I have designed about half of this car and I'm the main fab guy at the moment, and I have to do better than a B average next semester or declare my major as something other than engineering, its bullshit if you ask me.  Hopefully this will count for something if it comes down to it.

I am going to need some parts from you guys here pretty soon when I start building the header.

[Phate]

I'm on my school's baja team, we deemed FSAE too expensive.  Hopefully the dipshits in charge of the club will get their shit in order so we can actually get our money for next semester and buy steel.  I'm hoping to make a build thread as well.

Baja doesn't get to play with the engines, but we can do just about anything else.

[Passenger]

Add the bars and be done with it.
Looks like it is coming along nicely, and I agree, you guys are very well setup.

This.  If that section is not supposed to allow flexure, then whoever designed it doesn't really understand how to properly utilize triangles.

Just my uneducated $0.02.

[Passenger]

In case I wasn't clear, I meant just add the bars, don't ask, don't tell, do it when no one is around. Its one of those its easier to ask for forgiveness then permission situations.

Passenger is completely wrong.  You should not ask forgiveness, you should tell them FUCK YOU if they don't like it.

Anyway, what's the end-life use for a decommissioned FSAE car?  Looks like a cheap auto-x rig that would make the short course a lot more fun, and challenging, than a traditional car.

I think some do get sold eventually.  Our team tends to keep them around for development and driver training.

baja seems to be more fun and laid back, but I love tinkering with engines and going fast.... this doesn't happen in baja.

Now when I wanna go get muddy and jump shit out in the woods, I get on my bike and go to the trails.  thats close enough to baja for me.

The problem is getting one.  Our cars are "state owned" and cannot be sold except through state auction.  I'm sure some just turn up missing every now and then.

Another problem is how much these cars break.  not very many of the cars make it through all the events at the competition.

What typically goes wrong?

What typically goes wrong?

They are built by university students?

They are designed and built by inexperienced students?

That sounds redundant to me, a student by definition is someone that is inexperienced.

[Joseph Davis]

Well, I can't see a chassis that's undergone even halfassed FEA collapsing under itself, so I figured the kids were blowing the engines up because they lack the ear, or experience, to know that instrumentation can only be trusted so far.

If you need a tune or consultation, LMK.

[DSharp]

not all students are inexperienced.  Some of us just need that sheet of paper so we can get jobs.

here's some more shit I spent countless hours on....

You should come check it out sometime.  Our engine dyno needs a little bit more work, and our only running engine is low on compression, was built from a pile of parts by some students who dont have much experience with engines.  Ive seen a few shitty Engine Management setups on these cars and quite a few who had engine related problems.

If its fit and welded by a knob its not a stretch.
