The fabrication thread.

[feito]

does my own rotisserie count?

[C. Anderson]

I wish I could find a shell with that little rust.

[knifedag007]

My shell is just like that, if not less rust...same color too.
Where in Texas are you located?

[feito]

san antonio, and i didnt get it as a shell




today, or last night actually i started the other side, i figured i kinda messed up at getting the feel on the engine bay where it'd be all visible and making ugly welds so i had to make it even on both sides

[knifedag007]

Oh mine is a S13, but its that exact same color...hopefully i can be posting some stuff on this thread soon. I am nowhere near as talented as some of the people on here but I am learning

[feito]

my own coldpipe.

@jordaninnovations - Could you please clear a spot for a new PM?

[jilo]

found a good home for my sr. 91 cressida with minimal rust.

[Acidz]

Made this setup for a customer with an LS1 in a 180sx.

[IIIXziuR]

That looks great, Acidz!
What material did you use, 304?

[koukistylejdm]

so at the end of this tread i want to marry blu808

Whats up with that coating on the DOM? I see that all the time but I'd be so pissed if I got a batch with that crap all over it.

[G5SR20240]

I just recently finished the cage on our road race evo 9 mr

[D.Adams]

That sir is one hell of a good looking cage. You use JMR dimples ?

It all depends on what kind of DOM you get i guess. I only use USA DOM and its always brown the indonisia shit is silver but i hate using it. I clean the ends with a wire wheel just for a better weld. Even though i mig welded this cage i cary most my TIG welding techniques over.

Thanks! And yea all my dies but one are JMR, great quality

Yeah, its just weird, all the DOM comes all greasy and dark grey/black but I take it off with alcohol and a scotchbrite red pretty easy.

that stuff seems almost like a lacquer paint.

What are you guys paying for DOM?

Its 4.80 bulk 100+ft price in Austin, but 3.80 a foot just being some shmo in Houston.

[McRussellPants]

latest tinkerings.

Yea its all just rust inhibitor and it also depends on whether or not its china dom, and we usually pay about 90 bucks for 24ft stick. We buy in around 300ft at a time for 1 3/4 inch .120 wall

I pay $2.88 per ft if i order more then 100ft. I just placed an order for 160ft of 1.5'' .120 wall and it was $460.80 and its USA DOM i refuse to use the indonesia shit. The carbon make up is diff and i get all my dom certified.

here is the flickr i made for the car

this is the finished product did everything i could before returning the car 250miles away

Why do you tack weld your cages?

I also am wondering why you used trigger welding on such important parts of the cage, my guess is that xraying those joints you'll see poor penetration. Its a lot better to run a single bead and if possible all the way around the joint. Wouldn't put my life on line in that cage. There is no argument to this topic either, there is no physical way to put enough heat and penetration on that joint with that method

Not understanding where you guys are seeing the cages tack welded.
From the photos I see, only thing tacked in is the plates which doesnt need to be a complete weld all the way around, just good strong stitches to stiffen the car.

If you look at the welds, you will notice the weld is not welded with a consistent bead. They are done by squeezing the gun (trigger weld, stitch weld) and making a round weld and letting off the trigger
Good weld, good penetration
Poor weld, lack of penetration on thicker metal
If you weld you will see that when you start a bead, the heat transfer is less at the beginning of the weld then within the next 2-3 sweeps you do, that is what essentially is happening when you trigger weld, lack of heat on thicker metals like .120 wall dom gives poor pentration

Case in point, these are trigger welds. I usually would not blast anyone on this forum, but when people are building cages to save peoples lives in an event of a crash, i feel the need to point things out.

But it looks just like a tig weld

You have to know what youre looking at. What may look pretty really isnt.

Full beads around tube like so

[tauntdevil]

Thanks for specifying it. I didnt look at the images in full view or in detail, just looked at them them from regular view. Thought he meant tack welds like the ones used for holding parts together every 4 inches
