Well it's that time again. Here's our junk so far. Big thanks to Cartesian Tube Profiling for making this year's build fly!
And with our newest model, Gage. |

I don't think the tech judges are going to like your SIM, Chris.

Actually, this is how its done. Our first attempt at welding we decided wouldn't pass tech, so we had to make a 2nd try at it. |

I see nothing but little red x's from Chris... but I like the use of the DTNW process, that is Duct Tape Nascar Welding.

Laser notched tubes? Frame looks a few inches shorter length wise than last year?

That's just because it doesn't have the back half yet, it really shortens up a car if you cut off those heavy rear wheels and that whole engine deal.
You gotta look at the details.

CNC bent and notched by the good folks at Cartesian Tube Profiling. Anybody got any new junk to show off for 2012?

We have a lot of new junk in the works and have recently started serious fabrication. Our team traditionally doesn't like showing things in advance though so no pics yet... It's all about the surprise.

Despite me saying, "the shoulder bar needs to be 5" lower this year" we added a second shoulder bar. |

I saw that, and was about to ask... But I like the use of ratchet straps to square up the frame, we did the same thing with our nose this year.

The MDF works excellent for a one off vehicle. 2 sheets of 1" MDF were purchased for our 2011 baja and so far it looks like we'll be able to get the 2012 baja out of them as well.
The frame has been extremely precise so far. One bar is out by 1/16" and that was due to a piece of tubing being fish mouthed short. |

Since it's mostly glue and the fibers are not lined up an any particular direction (i.e. wood), it ends up being pretty dimensionally stable with RH and temperature swings in your shop. I think a sheet of MDF on a sturdy table is great for making a fixture for the RRH and other stuff all in the same plane.

Nice frame vivlashay! Which nodes does your front suspension connect to?

pfft tradition, we just dont have anyone on the forums no harm in progress update. I have some pics, but I went back to CO and left my mini USB cord in NY so I cant pull them off my camera... yet. The frame should be totally done by this weds, minus tabs (at least thats the plan, it was missing about 6 bars when i left). Should also have most if not all control arms done by then too. Got some front uprights done in the CNC before I left. Rear suspension is a departure from what we've done, but nothing new to baja. Car should be much much lighter this year. theres also1-2 new things that I'm excited about (not my projects, wont spill the beans) is the central michigan with the clearanced LFS tubes? does that make fitting a seat a pain, and have you have problems getting high centered in the past? also (dont have the post in front of me) but i think its kettering, those sims are interesting. never thought of running them like that. we've always mitered all of our bars with air tool stones. Our tube bending sponsor also struggles getting our tubes properly bent (LFS were bent almost twice as much as the drawing said, at least they got the hard bars doen correctly) so we have to revert to bending some tubes ourselves. Also drastically improved our jigging set up this year, making everything a breeze to set correctly. Its nice to have a grid of holes all under your frame for fixturing too.

What clearance are you referring to on the LFS tubes? We haven't had any troubles with fitting a seat with the setup we run. We have run the rake in our frame for the past 3 years, it gives us more clearance and helps with ergonomics...the reasoning behind it is that when the driver is seated his legs are bent and the area under his legs is unused so the rake reduces this area and allows for more clearance over obstacles. |

just the fact they arent flat. probably the camera angle, that point where they are moved up looks close to the firewall

It doesn’t seem to comply with the rules the way I read them. How do you justify it? I could be interpreting it wrong. |

The sim doesn't have to be continuous. Check out last years thread, we did the same thing.

This is what we have have been working on. The frame is almost all tacked together. We still need to add the front part of the SIMs.

Haha, yeah probably, our car from the last year had a similar firewall. But the idea for it came from TTU. The lower side tubes which are kinda hard too see have some pretty wicked bends in them. It's one continuous tube from the firewall to the node the SIMs will go into.

yeah, bends like that usually take a few tries or someone with a bit of experience. Unless you have bending software and a bender that's calibrated.
I like the idea of using bends like you got, its something you can actually justify in design judging. Your reducing the frontal area and increasing top speed. I estimated last year that we were loosing close to 3 hp with a speed in the low 30's. Every little bit of that firewall you can get rid of helps.

I wasn't there when they bent the first set but I think they got the firewall bent on the first try. I think we figured last years firewall was about 1sq foot smaller than our previous design. The floor tubes were bent twice. There are two bend planes 34 degrees apart... It was kinda tense bending them and not bending them too far.

Dang it we need to stop throwing out all our old firewalls, they keep popping up on other people's cars. On a side note, when we did it, we made the bottom quite a bit narrower.

Only an unofficial one. It's called the "Try-to-move-the-frame-by-grabbing-a-freshly-welded-node". What you do is burn the shampoo out of your hand then flail around like a crack head on your way to the sink.
