| Bend Tech software
Does anyone use it? Bend-Tech Products I'm going to be building a cage for my mj either this summer or next summer. (Depends how much time and money i have left after i get all the critical stuff done to it)...and there's 4 other jeeps that needs a good cage built and i'm guessing that'll be this winters project for afew of them. So, i'm thinking some software may be a good investment so we don't waste aton of dom with bad bends. We have a pipe bender that looks something like this, i'm not sure exactly what brand/model it is....but so far all its/we've done is coilover hoops, stingers, and other misc stuff....Biggest i think we can bend with it is 1.75" 120 wall DOM |

I used it a couple times, but usually had better results using a tape measure, marker and eyeball.

Disclaimer: I built nhra chassis for a while but I have never directly used bendtech although I do have some cad experience. I really don't think it makes sense to draw a cage unless you are planning to mass produce them. Chances are that unless you spend a LOT of time in front of the computer then your first drawing won't fit quite right and you will want to make revisions. Cad software is great if you want to invest the time into it with the intention of making identical production pieces. If I am just building one cage then I'll attack it with a tape measure, a digital angle finder, and a couple pieces of tig rod so that I can rough out a bend without bending tube. |

Well, i'm not really sure what i want yet cage wise and it'll let me tinker and see how stuff will look. But, the main purpose of it is to get the bends correct because it tells you exactly how to position that pipe in the bender to make it come out right....Having to bend up 5+ cages in the next few years i'm sure it'll pay for itself in wasted pipe. I'm also pretty proficient with cad software...i've got experience with AutoCad, Inventor, SolidWorks, FeatureCam, and a couple circuit board cad programs. So i'm not worried about the learning curve, i'm just wondering if it is actually useful for making the bend correct the first time (From the few misc things we've done we usually have to throw it in the bender afew times to get them right....and have had to scrap some stuff before) i'm not too worried about the modeling because i have solidworks and i know it can model cages (I haven't tried to figure out how yet though).... i just think it'll save time and money when bending the cage, it be awesome to have it all on the computer; bend a piece then tack it on vs having to figure out how you think you want the pipe, try and get the bend right in the bender, test fit, throw it back in the bender, test fit....etc. |

No--all my bending is from inside my head.... Also don't confused between pipe and tube---2 different materials. |

No, i don't even think theres any tig rod in the garage, if there is i don't know where its at. We just use a mig for everything (Have a Hobart ironman). And, we have scrap/junked pieces for looking at the radius....its just getting the bends in the right place and accounting for the spring back correctly (and not over bending the tube). I think this software will help make the bends correct the first time and save alot of wasted tube, but i'm looking to see if anyone can confirm it. |

Edit: Tube vs Pipe isn't material difference, its a manufacturing difference. Tube is made with tighter tolerances than pipe, usually pipe is simply to transport something (like water) and tube is for structural applications Last edited by losikid; 05-20-2013 at 01:46 PM. | |

I do remember one time it failed us, we were bending a simple hoop roll bar for a truggy. The owner wanted it to run from one slider to the other and be just proud of the cab. We plugged all the measurements in, then bent the tube according to the program. it came out 6" to wide. It all worked out though, we just added 2 more bends about a foot above the sliders to kick the legs back in. |

Did you double check the dims entered into the program? | |

I can tell you (by running thousands of feet of tube thru my bender) is they may say they use the same material to make DOM/HREW but the end result is different between the 2. ANother thing is the spring back is different from not only material but also the wall thickness and each tool is a little different. | |

| Re: Bend Tech software Yes/no. I understand the wall thickness plays a part in OD but all the stuff I use (off-road) is based off ID (where I understand the industry has changed over to OD). Plus all your fittings/couplers are based off OD of whatever material you are using. Personally I could care less about PIPE as 99% of what I use is tube. |

| Re: Bend Tech software I had a dune buggy built out of pipe (it was scrapped out of a remodel). That thing weighed a ton and it was far from rigid. But it held together. On the sides there were like sliders so if you got to close to a rock or tree it slide the buggy over so the rear tire didn't hit it straight on (the rear was like 2 ft wider than the front). I pulled the cutting brake a wee bit too long going around this corner at like 30-40mph and slammed into a massive boulder really hard (if the harnesses weren't on we probably would've went to the hospital). And i actually think the pipe made it a softer hit, as it bent in the pipe like a foot (till it touched the main chassis). Also, when i launched it afew feet in the air or if you watch it (as a spectator) in the whoops the whole front end would act like a spring, lots of flex/deflection...kinda scary, i was always afraid that one day the front end would just snap off.
