    There is a tools to specifically bend tubing. One of the Four Wheel magazines had a tech on one. I can't find it must of put it in storage. One version was manual and one hydrolic. Maybe someone remembers which one and you can check there website. Or you can do a search for "tube benders"

    Specifically how big are you talking about? HF makes one that bends pipe up to 2" or so, maybe a little more. You can get it on sale for $69 or so. "Tube" benders (like most use for cages with *tube*) generally run $500 and up with one size die, each die will set you back another roughly $200. You can get pipe dies for the "tube" bender too. Sizes go up to something like 2.5" I think.(?) Anything bigger, I have no clue other than high $$$$ pro and industrial stuff...

    damn, dude -

    I've never seen anything that will bend stuff that big...not saying it doesn't exist, I've just never seen it.

    Anything I've seen done with pipe that big was done with pre-fabbed 90's or 45's and welded.

    If you do find somehting that will bend it, I can guarentee it's gonna be BIG $$$.


    You do realize that 10 foot of 6 inch galvanized conduit weighs about 177 lbs. don't you? 8" will weigh somewhere in the neighborhood of 250 lbs per 10 foot.

    I have never heard of anyone wanting to bend anything that big, that big you cut it and weld it bag together. The stretching would make it to thin on the bends. Pro Tools
    The biggest they have a tool to do is 2" but they have a cool computer controlled one /forums/images/graemlins/tongue.gif

    Oh, you can bend it. You just need a bigger bender.

    That's the whole idea. Heavy pipe can take the beating when you hit trees and stuff. Who cares if your front bumper weighs 150 lbs?

    Some people don't like the look of the front sagging 6 inches lower than the rear? /forums/images/graemlins/rotfl.gif JK man. Maybe go thick alumimnum pipe of similar size? But then you would need to be damn good with a welder!

    I would say that 6" or 8" is going a little overboard... 2 or 3 inches should be sufficient

    The reason I said galvanized conduit was I'm an electrician and I got those weight quotes out of a conduit bending book

    it should fairly close unless you're talking about some kind of thin-wall stuff - all galvinized conduit is is steel pipe. I had to guess-timate that weight for 8 inch, since the book doesn't go that high. Of course, conduit is measured by the ID, not the OD, so there may be a differance.

    here's what I got (all are per 10 feet):

    1/2" = 7.9lbs
    3/4" = 10.5lbs
    1" = 15.3 lbs
    1 1/4" = 20.1 lbs
    1 1/2" = 24.9 lbs
    2" = 33.4 lbs
    2 1/2" = 52.7 lbs
    3" = 69 lbs
    3 1/2" = 83.2 lbs
    4" = 134.4 lbs
    5" = 134.4 lbs
    6" = 177lbs

    Ok - found a tubing/pipe manufacturer online. I see what you're talking about now...you're talking about the 16 guage stuff (41.2 lbs per 10 foot)
    (the conduit I was referring to is schedule 40 - thick stuff)

    here's a link to that chart

    Pipe Chart

    here's a place that can bend up to 8" for you, but I'll bet you'd have to mortgage your house to get it done

    Keep in mind that when you smack something hard with the "worlds strongest bumper" /forums/images/graemlins/wink.gif that it will transfer the impact to the frame instead of bending. I'd rather bend a bumper than buckle the frame. /forums/images/graemlins/shocked.gif
