Use the proper welding techniques. Mig or Tig and you can't grind any of the welds it is forbidden to get the OK from Tech inspection.

Art Morrison (chassis builder) has a VHS tape you can buy for $20 that shows you how to back half it with a full frame or half, install and set up your four link, weld brackets for coil over shocks and panhard bar, install all the tin including wheel wells, and floor pan, package tray and rear fire wall for fuel cell and how to weld brackets, weld up an 8 point cage, tie it together for a ten point, and run down legs to front sub frame for a 12 point. He does all of this in a '72 Nova which is the same as a first gen Camaro, and would be similar (though you can not use his dimensions) for your second generation bird.

Best buy I ever saw for $20 bucks only because I already own a Nova and I'm thinking about cutting it up and gutting it for another project. Your value may vary.

fit-up is critical with TIG. you can weld a gap with a TIG but it is very difficult. for a roll cage i dont recomend it (filling gaps). if that is an issue go with MIG. how much time do you have under a hood (welding hood) ?

I'm a professional Tig welder and fabraciator, measuring and proper fitment is very important. The weakest point of any welded joint is going to be where you had to fill a gap because it was not fitted properly. I would say any gap of an 1/8 inch or less wold be ok. I would tig weld if you have the experance and the means. You have more control over the bead. Take it from me I have 1000's of hour under a hood. I would reccomend 3/32 size of filler rod. For proper weld penetraion you will nedd to weld at 130amps.

I would also have to ask if that kit was made of chromemoly tubing, which though very strong for it's weight is brittle and can be made even more brittle by excessive heat generated by gap filling. One would assume when buying a kit made for a car by professionals that all ends are fillet ground after being properly notched and will "fall" together. One hopes anyway. For a first time attempt I would recommend mild steel tubing as it is more malleable if you ever do need a cage and stronger over time.

That will be a mild steel cage. I would Mig weld it myself. If it was Chrome Molly Tig is the only way and no gaps.

the only experience i have is exhaust work 100% overhead and i think it definately gets easier (position wise) from there

i will be mig welding and its a mild steel cage not chrome

One important thing I forgot to say is use a 220 volt Mig! Rolling Eyes
The 110 takes too long to heat and go and will never have the penetration because of it!
Remember you are welding .135 not .055 as in exhaust.

I forgot the 110 volt migs are so popular these days? Shocked Crap

Wow! The thickest exhaust I have worked with is 16 GA at .065 aprox. .090 would last a life time!

Back to the 130 amp forget it welding a cage. I have seen it done and will never ride in or drive the car racing!

As stated earlier the penetration is not there until you are midway through the weld!

well its apparent im wrong about the thickness of our pipe
its probably the .065 you mentioned

im not a pro at welding (judging from my experience) Rolling Eyes
i suppose i could always tack it up and get a pro welder to weld it right

im thinking that would be better than getting the buisiness from tech inspectors Head Bang Head Bang

im getting ready for possibly 11.99 or better and i dont wana get kicked off the track Driving

I am so glad you didn't go ballistic on me as others have done! Laughing Laughing

I can see you want to learn as all of us do.

If you don't think you're welds are good enough, have someone that is good weld them!

The inspector is only looking for you're safety!

I witnessed a 70 Nova that crashed on the big end doing 100 mph and died from the 14 gauge exhaust pipe roll cage coming apart and stabbing HER multiple times! She would have been been better of not having one at all.

Use common sense is all I say!

If you are welding with the 130? NO way. If you are welding with the 175 yes!
