Outer Limits 4x4 Board

Ive just got myself a new 16 Ton 3" pipe bender and am going to make myself some bar work starting with rock sliders what pipe do you guys think will be best ?

I was thinking 2.5" 2.9mm gal pipe or is this overkill

now having a look at everyonr elses maybe 1.5" would be more realistic I just want to make sure its strong enough as im not sure how strong i need

how much was the bender and where did you get it from

About $260 from ebay including freight

use cdw or cds, 42nb ??? gal is a wast of time and pipe is shit

the shitty sliders that came with my patrol are 2.5inch x 2.9mm pipe and they have had the entire weight of the car dropped and held on each slider without any flex.

pipe is fine for sliders in my opinion. cages need to be tube for sure but its only sliders, just get a thicker pipe than you would use tube, pipe is half the price of tube.

can you post a pic of your bender please, Ive been looking for a 3" one but they all seem to be 2"

check the benders you are looking at, it may well be you can fit a 3€' die in to it, but comes with a " die?

had one of them for years......does limited and shitefull bends!

Ive got the same style of bender and have to agree its pretty ordinary.

Would love to find something better at an economical price for the DIY person.

Totally true. Is hugely improved with a proper Dawn die but still fairly limited. Can get easy 90 degree bends with the Dawn but it is a wide radius compared to a real tube bender. Without the Dawn I get a pimpin' 22 degrees before it kinks the tube.


Having said that, I think Wendle built his first buggy using the above combo which was hella sweet so I guess the user comes into play a bit. YMMV.

3 buggies thus far.
Plus some miscellaneous roll cages and bumper bars and stuff.
FWIW the Dawn die forms a tighter radius than a Speedwerx bender.
Can do 180° with the Dawn die, but it's a lot of trial and error and a good 10 minutes of actually loading the bender and cranking the handle

ive been told by others that a good die set makes a big difference

good luck with that.. but you should of saved ya coin and got a tube bender.

If you serious look at a JD bender and tube. Once you've played with "cheep" benders, wasted a few lengths of pipe and made your pride and joy look like a 30 yr old farm ute, you will think it was the best thing you bought (other than a cruiser).

whats the difference between pipe and tube

wall thickness

dirty dirty 4x4 wrote:whats the difference between pipe and tube

Very little.

There is more difference between the different grades of tube, or the different grades of pipe than what there is between the two. Both come in a huge range of wall thicknesses and manufacture type.

For someone to say that your car is gonna look like a farm hack if you use pipe, or your cage will fail and kill everyone is pretty uneducated. It's all about choosing the right size material (either pipe or tube, doesn't matter) and having the head for an intelligent design.
You'd be surprised how many of the buggies in Aus are made from pipe, and how many dozens of rollovers most of them have seen.

The problem with buying equipment for bending is that the range of sizes for tube have a different set of outside diameters to the range of sizes for pipe. So you need to decide what material you want to build with before you go buying your tools.

I wish i had a little more info before i got it but this is what ive got so im going pipe but thanks for the info. I dont suppose you could tell me the difference in sizes and what i should be lookig for

The sizes you will most probably want to use are underlined in green here. 25NB, 32NB and 40NB. You might even want to go up to 50NB if you're after that B+S roll bar type look
Outside diameter is marked just to the right of them, and wall thicknesses available next to that. Standard (approx 3.5mm) should be fine.

The Dawn dies are available from Blackwoods and are listed on this page - http://www2.blackwoods.com.au/infoBANKp ... &P=2026375 - note that you want to order them by the NB size of your steel.



Hope this helps someone.

thanks great help

pipe is measured by inside dia.. and is made to carry water and gas

DOM tube id measured by ouside dia.. and is made to be used in automotive fabrication

the question should be... are you a plumber?

anyway worth a go with your new bender,, post some pic's of how it goes.

but you may just be stirring the pot

Pipe is measured by in internal diameter as it is internal volume for passing fluids that is of most interest to people the buy it.

Tube is measure on its outside diameter for fabrication as this is important when working in a structural environment

It is a matter of what tooling you have to work with the material, most (including you) have a set of dies and notches and work with tube as the wall thickness doesn't change the outside diameter.

The discussion about which structurally should be used for an application involves the type of steel and its welding method and wall thickness. You can use low grade steel pipe just need to up the wall thickness to suit.
