minimum rollcage tube size

[LandC1973]

FYI - Because of the link below (and others) and computer modeling I went with 2" standard schedule 40 pipe for my cage because of price, welding considerations, and I not racing fast on dirt tracks.

tube strength vs schedule pipe

Is schedule 40 pipe strong enough? [Archive] - CK5 Forums

Brute Muscle strength...I've been hitting the gym real hard and eating all my veggies, lol.

Hydraulically via some fancy overpriced bender. I'm learning about bending, a friend is instructing me on the how to.

2" .120 Dom will hold up just fine in a violent 80 roll (multiple) as long as the cage is built right. I beleive Nascar only allows Dom to be used because chromo is too brittle?

Mark was that the size for the Baja80 you boys built?

i built my whole cage out of 1 7/8" schedule 40 i believe, i rolled it and it didnt budge. you just have to put gussets in the right places and keep as many bars straight as you can. i only have 4 bends on my entire cage. also if you use an exhaust bender it makes a stronger tighter bend. thats what i was told and it worked for me.

please don't use an exhaust bender......

It depends I think on how big of a dick you are to people.

If your a big dick= sch 40 PVC

Not a dick= DOM/HREW


So to decide what you should make your cage out of, you must first find out how big of a dick you are

A cage is not something to cheep out on...

Now... DOM or Seamless? 1010 or 1020? Or is it A513? Normalized is which? I am not looking for a chemical brakdown of these materials, but what is it I am looking for again?!!

Have you read this article on Pirate??
Pirate4x4.com - The largest off roading website in the world.
Its mostly about Suspension Links but has some good info on differences in steel , Somewhere there is an article on the bible of metal strength, but i cant find it now

You mean i shouldn't build a cage out of Poop Pipe (Sch 40) with a Harbor Freight Kinker ?? Its just a Safety Item

I hadn't seent that article. That is exactly what I was looking for.

Muddogbob, I appreciate the lead. I'll give 'em a call.

lowtideride -- Wait…who the hel- said PVC (Polyvinyl chloride) pipe would work. Yes that is a really, really bad idea. I’m talking about Steel Sch 40 NOT PVC Sch 40.

PVC = Death

Yulp I Know what I said.

It was a joke.

On “Trucks” (the TV show on Spike TV) they actually got an old Bronco and someone used PVC to make the roll cage and painted it black. That’s why I didn’t know if you were joking or not, it’s happened before.

DOM and HREW are definitely stronger per the weight but Pipe is easyer to bend, weld, and cheaper per the strength… If you don’t care to much about the weight Sch 40 or 80 could be a good option.
