feasibility of a DIY Roll Bar

Ok, so we all saw the thread where the dude built a horrible looking roll bar.

Seems to me, that with a harbor freight, welder, and a bunch of pipe, you could build one DIY style.

Is it feasible?

Would it be safe?

Lets make some assumptions here.

  • Average at-home welder
  • Materials are to the proper specification
  • Builder is following some sanctioned club’s(scca,nasa,etc…) guidlines.

Also, keep in mind this is a roll-bar, not a full cage.

It’s much easier and safer (maybe even cheaper) to just buy a bolt in roll bar.

unless they don’t make one for your car…

Don’t ruin your Z

You were just trying to sell it now you want to put a roll bar that can’t be removed in it…

no, not wanting to. Just a thought, seriously.

But the thread from yesterday has me wondering if people ever do this as a DIY.

edit: I don’t even own a welder anymore. I sold it before I moved(bad judgment call) :frowning:

A pipe bender is not a tube bender. There will be noticeable differences in the bend quality.

A proper weld is a proper weld, there should be no grey area. If you have to question it, chances are it is not done correctly.

Material is pretty straight forward.

Even building a full custom cage buying a premade main hoop from a reputable company is a good idea.

I’m all for DIY projects, but this is an area you probably just shouldn’t mess with.

Bars and cages should never be a DIY for the average person. You should always leave that in the hands of a person that has experience. You may never need it, but when you do, you will be grateful that you paid an experience person to fab it.

You need expensive tools to make any part of a cage. Benders, notchers, and a good welder are needed. Crappy HF tools will yield crap results.

yeah, I wasn’t really sure what the capabilities of the HF benders are.

talk to mike at innovative. His cage guy does really good work, and is VERY VERY inexpensive.

I’ll cost more in tools/materials to build it than this guy charges, thus saving yourself the time and having it done by a true professional who knows specifics about certain sanction’s rules.

i have a HF bender, i used it to make the strut bars… it made OK bends, but i really made sub 45 degree bends with it…

you would need to spend the ~ 4-500 bux on a j2 bender to be able to make a good cage bend…

and then you are already into the price area of somebody making one for you…

doesnt your Z have factory roll over protection anyways?

I am not putting a roll bar in my car. For several reasons.

That was not the point of this thread

what?

not gonna lie i laughed.

me too…

Victor Puglia Jr. and Jason Vitez do great work. I’ve had great experiences with both. I’ll get some close-ups of the TIGs when i get a chance
