Nice. I see you used a wire coat hangar as a filler rod. I like to JB Weld cages to save myself from welding fumes. Good old racers tape does a good job holding tubes together for the 5 minutes it takes for the epoxy to dry.

sexy, how much to do one up for me like that!?!?!

JB Weld? Bah, PVC pipe FTW!

To this day, I WISH I would've had a camera with me the day that I saw a Honda Civic driving around witha a PVC pipe cage in it... You could see the cage moving! It was FANtastic!!

Tech inspection at Englishtown (http://www.racewaypark.com/) requires all PVC cages to be painted black. Muffler tubing and stove pipe cages can be run bare.

Interesting, per tech inspection how think do the rubber bands holding them together have to be?

I think you did real good. It's tough welding the pipe enough that you hide the threads:D

You guys are idiots. Use this stuff:

I have some custom roll cage tubing that can hide those welds

Just out of curiousity, why the asymmetry in the back? Is there a reason to have it offset to the left?

That's an e30, as far as I can tell...
And in the e30, that's where the diff mount is...

Yup, thats where it is.

God damn that is hawt! :buttrock By the way, thats copyright infringement, where is my royalty check?

Also, what is with the internet slang of spelling "the" "teh"...I don't get it. Other than implying the person is dumb, what's the point? I know its common to be used as an insult, but seriously, thats one of the worst internet slangs, up there with "pwn."

LOL, I thought someone just misspelled it on the diagram and then everyone was making fun of it.
But, there it is in wikipedia ... http://en.wikipedia.org/wiki/Teh

Work in progress.

You've got some good and bad going there. Is this for a particular race series? Because you're actually not meeting certain rules. For example the rear down tube should be attached to your 'plinth'/rear fabbed up shock tower not to another tube. A bit of a load path problem I'd say mounting tubes in such a fashion. You are also not connecting the tubes at the nodes. The welding looks a bit questionable in a few places, the one picture perhaps because of the resolution makes it look like you have a crack in the weld but for sure the other tube isn't welded all the way around. Those are just a few things you can clearly see, an actual inspection may reveal more. Is this a home project? I'd try to get an inspector to give you some input as this cage may not pass tech depending how strict the inspection is.

Sorry dude.

-Carlos.

do the BMW CR modified cage rules remove the requirement for all tubes to end on plates?
thanks,

Eye am teh pwn.

Trust me, the welds are fine. As for the rear down tube, many have been done in this manner. The rest of the body will tear away before this tube comes off. The pic below is not mine but from another well known cage builder. I have built many cages. All have passed tech and some have even been "tested". This one just happens to be in my garage.

Personally, i'd prefer not to have the body tear away from anything.

No offense, but what is the cage builder of the above picture "well known for?"

Do you have any pictures of cages you built that have been tested? I'm interested to see how they deformed (including the chassis itself), thanks.

Obviously the picture you last posted was an existing cage being modified, is that Jareds? The second builder did a good job, but he was forced to use the existing cage, which has obvious drawbacks.

Also, on your car, i would suggest looking into a collapsible steering column, or a telescoping universal shaft to go from the steering column to the rack. God forbid there was a front impact, that would become a very strong thin object pointed right at your chest.

Actually, that was the wrong pic. I will post the correct one. I think that is Jared's though.

Yea. He made the best of his situation, Kfab does very nice work.

I guess its just a pet peeve of mine, but when its so easy to make tubes intesect and create much stronger nodes, I hate to see it not be done, as I see it in multiple locations on the cage posted on the last page.

And in regards to the first joke weld picture...unfortunately, we cut out a cage or two at RRT from customers who had us redo their cages and they looked like that, actually worse b/c some tubes only had the weld bead go half away around!

Well, Im pretty sure that wouldn't be legal in BMW or NASA if the right inspector looks at it. The required tubes must end at the plate and have a 360 degree weld. The rear down tubes are Required in the rules. Those rear down tubes and the ones from your other pic's end at the cross tube. It's all in the rules, just read them a few times. I know PCA allows about anything after reading their rules. Don't know about other sanctioning bodies. Just my opinion and I'm not that smart..;)

I know "tear away" probably wasn't the best description. The steering column IS a collapsible unit. I do have some pics somewhere of the "tested" cages. The tested cages all resulted the drivers walking away unhurt. IMO, criticism can be constructive. Will this be a safe cage when I am finished? I believe it will be or I wouldn't get in it. Is it the perfect cage? I don't think there is a perfect cage.

I barely call this criticism, its a constructive analysis :)

I agree, no such thing as perfect, but I do think there are easy ways to make it safer/stronger with minimal design changes.

Oh is there a collapsible section under the towel? I see now, thanks.

How far is the steering wheel from the Rod end support?

12". I was worried it might move around a bit but it is rock solid. I considered the Woodward column but went with the Sweet column. Pretty nice piece for the price. I am trying to work within a "budget". The Woodward was not in it.
