I have one that costs less than $100.00 that I bought at Harbor Frieght and it is a pipe bender not a tubing bender. It does not work on thin wall .095 roll bar tubing. It just folds it and does not bend it. It might bend water or gas pipe but not tubing. Save you money.

If you fill the tube with sand before bending, it should'nt kink.

Pipe bender: The $100 one you saw is for pipe. You can put a shim in it to get to tubing size and make bends without kinking (must be THE right size shim). However it will bend tubing the same way a muffler shop will -- it will reduce the diameter of the tube in the bend.. This loses some of your strength.

Tilley mentioned filling the tube with sand. Yes this will work. Fill it with very dry sand, plug both ends securely. Heat using a torch with a rosebud tip and you can bend the tube around any two substantial points. Sure is lots of work. SLEEPY

I should have posted pipe and not tubing.
I was looking for a way to bend roll cage pipe,and it sounds like 15a didnt have much luck with it. so how do you guys bend your roll cages?

roll cages are built out of tubing. pipe is what****runs thru.

ez bend bender with 4 dies is only 800 bucks makes nice bends every time and bends upright so you can just put a magnetic angle finder on the pipe and read your angles directly of it.

thats what I have.

I use .095 schedule 40 pipe. The bender works great. The pipe size is 1 1/4" in side and a touch under 1 1/2" outside. Most cages these guys build are not suitable for racing. Many are only .047 thick. They will crush in a roll over. Life is already to short,

schedule 40 like your saying you use would not be .095 thick it would be, .22, theres a huge difference.

.095 DOM is .095 thick.
.095 EW is .088-.100 thick.
schedule 40 is for a sink.

just so you know 1/8 is .125
1/4 is .25

DO NOT USE PIPE FOR A CAGE!

Pipe is made from re cycled steels, which includes axles, ball bearings, tin, chrome and even some aluminum. You will never know what the alloy is unless you take each joint for a lab analysis. Pipe is designed to hold 60 pounds of water pressure.

The schedule 40 pipe I use is not junk pipe bought at home depot. This is quality cold rolled and welded. I looked up the actual thickness is .140 and makes a very nice cage.

Bigcityracer, I have never seen quality cold rolled welded schedule 40 pipe. MEASURE the wall thickness and the outside diameter. Then let me know where to find it. I would be interested to have a source. SLEEPY

I have seen this topic go on long enough and I feel like I have to speak up now. What i learned working for Harris Auto Racing from 93-late 97 is so much that most of you wont learn what I did for many years to come. One thing that was always stressed and checked from time to time was QUALITY OF MATERIALS AND EQUIPMENT.

I cant stress enough the use of the proper materials and equipment to build chassis cause you or someone elses life may depend on it. I also want to add if ones welding is not up to par at least tack the cage together and get someone else to weld it up, I have seen a few guys get hurt from collapsed cages or from broken welds due poor materials and or welding.

The materials come from D. Wexler & Sons, Inc 4821 S Aberdeen St, Chicago, Il 60609, ph 773.927.0440. I don't need to measure these are the size from there Steel Products Catalog. They are a small local company I don't think they have a web page.

I have to agree with custom on the welding.I tacked my cage together and had a friend that welds for a living finish it. my car rolled 4 times and the top halo bent but not one weld let loose. I walked away because of good welding.
