Home Made Roll Cages?????
ok well my cousin gave me a great idea... he said why not use a manual hydraulic pipe bender to bend the pipe in order to make our own rollcages.... and im thinking... holy ----.... thats fucken clever i would never have thought of that... now my question to you guys is do you think it would work... and what size pipe and gauge thickness do they usually use for rollcage setups
?
heres a pic... and heres the link... let me know if you guys think this would work, if its ever been done... or is it just a waste of time and money...

Re:Home Made Roll Cages?????
sure it'll work. If you buy a roll cage for an american car you get a bunch of tubing, some being bent, you get to make it fit yourself. Making the bends right and getting it to fit well is the tough part. You might want to look into ordering one from a company though beause some places you can get them to make you a cage just from measurements of the car, and they're not expensive
I wana see -------- make the roll cage, someone help him with the size piping/thckness. I am sure that thing wil bent the right size pipe,

This can be done, but there are a few point to be made.
- Better quality roll bars are generally constructed from 120 wall DOM tubing. Cheaper ones are from 090 wall non-DOM tubing. (What do you trust your life to? I'd want the best I can make)
- Tubing is sized by OD, pipe is sized by ID.
- That Harbor Freight bender is for pipe, not tubing.
- If you bend tubing in the pipe bender, it will create wrinkles in the back side of the tubing.
- Each wrinkle is a great place for a tube to collapse under stress, like when you roll the car.
- If you build your roll bar out of pipe, it will bend correctly in the pipe bender. But I have no clue what might happen under stress, and don't think I want to trust my life to it...
We have made rock rails for jeeps using that exact bender and pipe, and they have faired well. Just not sure I want to have a roll bar made from it....
Two cents from Craig

You need to take a class on strength and materials to learn how metal behaves when you deform it.

Can everyone quit quoting every single part of a post they are responding to? We just read the fucken post before yours, no need to try to make us re-read it. Damn. <rant>
Ghetto, I thought this was a good idea, but I think maybe we should buy the hoop from a manufacturer, and we'll add to it with straight pieces. Most bars I've seen in mild steel are 1 3/4 pipe with .134 thickness.
www.swracecars.com sells a 8 pt. hoop for like $150 plus shipping.
