tube sizes.

well this is a very general quiestion so ill try to make it more specific. the quiestion is what size tube will be suitiable for a roll cage, it will be dom of couse, but what size. i plan to build a buggy i have access to a bender with a 1.5" die. i can buy a bigger die. so what are your thoughts. i plan to make the blazer at least a foot narrower, and hopefully alot lighter. as in no roof glass interior jive. but it will probablly end up being heavy. oh and i plan to roll it alot.

If you are at all doubtfull about your engineering skills use bigger tube. Like 2".

I will be building my cage out of 1- 3/4 in DOM.

do a search, you will find a ton of discussion on this subject.

i am using 2 inch DOM for my exo cage and flatbed frame, with lots of bracing and gusseting. i think it will hold. i am a master welder of sorts. everything but tig.

im not to doubt full of my engineering, i do plan to use alot of triangles. and what not. like i said i realized that my quiestion is very vague, i may just buy a 1.75 die for the bender, but that still leaves me to choose what thickness of tubing. i just wanted to know what people have used and what works and well dosent. what im building will not be the same size as a fullsize, it will have d44front gm 9.5 rear. dana 300,700r4 sbc and link suspension front and rear. i plan to run 37s with superiors and ctm. but as of now i have a severe time crunch and basically the faster i start welding and making the main frame the better off i am.

1 3/4 .120 wall DOM is what I would use. some guys dont like the extra cost and use .120 HREW tube.

Well, I've used 1.5" x .120 wall HREW tube on 2 rigs I've built - this one being the latest:
