How can an exo cage be built correctly?...is that a question that is allowed to be asked without useless commentary?!
As u know...my sheet metal is fawked so to save a life...if it can be done right...how so?! Its a simple enough question.
with structure that goes into the cab and at least lands on the body mounts. Tie your seats and belts to it as well and attach to the fame as good as possible. Lots of triangles and few rectangles... good node structuring. Material prefered is dom pipe tends to fracture HREW dents more easly and will bend with too much vertical load but will hold up ok if designed properly. last have some one who knows how to weld good glue it together for you. in your design think of the structure as a whole all in push pull senarios. ask yourself these questions (if it gets impact here where is the energy going to transfer to). cage sould try to take the impact through the wole cage and not one isolated area to dispurse the load. and last no real long spans.

Great advice but he has no frame.. It'll take a whole lotta plating of the unibode to make it strong and safe.

and "DOM" is not necesarily the right material.
:stirpot:
so your saying a cage made with hrew is ok if designed properly, even though it has half the tensile strength of SOME DOM? (1026 CRDOM is about 87Ksi, and HREW is about 45)
therefore you'll need twice the material, and with the added weight your safety factor goes down making it a mute point.
I want to see REAL information here, not speculation and hearsay.
Im not a cage designer, but i know steel. it doesn't matter how good your cage is designed if you use the wrong material. and "DOM" is not necesarily the right material.

Unibodies are strong as ****....the key is to land the tubes/legs in the right spots...when done properly the end result is insanly strong......go ahead and argue....but your wrong....this is the proof.

A picture of a stripped and tubed xj sure does make me wrong.. I have a buddy that is doing the exact same thing with an xj right now. Welding tube to plates and plated sheetmetal just doesn't smell like the hot setup to me. I guess I should throw my fully boxed frame away and start over with a stack of 18 gauge... :haha:
Ya, jeepmauler......so there, TAKE THAT......
My Jeep Grand Cherokee is hard as ****.:redneck:

Jeff..Please tell me that is up at the OM...
Iam all ears about your build up on that xj:awesomework:
So your just gonna land tube on on a stock Toy frame and burn it?.....with no plating to spread the load?....No wonder your last pile came apart after your little roll down the hill:haha:
