Tubing bender questions
Hi all,
I'm investigating buying a tubing bender. Eventually I'll want to bend tubing for a car chassis, but currently I have a need to do some decorative type bending of square and round tubing. I know that the Hossfield and its knockoffs will do a good job for the chassis tubes, but I'm wondering if they can do increasing or decreasing radius bends for the decorative stuff. I'm thinking that I could make a series of low angle bends, each one with a larger or smaller radius than the bend previous to "simulate" a long variable radius bend. Can the Hossfield type benders do this? The info I can glean from the various sites I've visited, makes me suspect that these benders can't, but since I've never used a tubing bender before, I could easily be wrong. Can someone enlighten me? Thanks, Peter |

Thanks, Peter The JD Squared and Protools benders are both very popular for car work. http://www.pro-tools.com/ http://www.jd2.com/ There are fancier benders, but the cost will escalate rapidly. The JD Squared Model 2 is a very affordable machine. The real cost is in the dies. |

Peter 2 very different concepts and applications. Draw benders are for making small radius bends in thin wall tube without collapsing the tube walls. Ring rollers (aka- angle rolls) are for making large radius bends in tubing and bar stock. To make a spiral tube usually requires a special CNC controlled power bender. |
