If you wont go to the trouble of converting 17 measurements to metric you certainly wont go to the trouble of making this.

Thanks, Mad4Rnr, for sharing your design. I may build one of these.

I guess that I should post the one that I made. Mine is made out of steel and I have modified the design some. I switched the placement of the static pin and the swivile pin. I also made a couple of collars that get placed on the pin attached to the handle, this allows me to bend diferent thickness of material. I can also place the collers on the static pin to get a different size radious on the same thickness of matereail.

This type of bender design can work quite well if you add grooved rollers that go over the pins. This way you can better support the tube and adjust for different bend radii that you might want. One thing to remember is that the groove in the die does not always have to be round like the tube. A square groove can work just fine as long as the bend radius in not too small. When bending large tube for 1:1 cages the basic acceptable SMALLEST standard for bend radius is 2.25 times the tube diameter. So for 3/16 tube you would get a raduis of .42 or a 180 degree bend in just under 7/8". Everybody always tries for tighter bends but I tend to stick to the 1:1 rule. You can get tighter but the tube must be fully supported by die blocks in a rotary draw bender but even that depends on tube wall thickness. I have found that as long as you stick to 2.25 or 2.5 times the tube dia I can make bends flawless every time. But then again I have a really special bender that I built. I will post a picture later to give you guys some ideas. For inspiration take a look at professional cage building tools and see what you can come up with. I recommend trick-tools.com Fastball |

Fastball, that's exactly what I'm concerned with. I'm going to build a bender, but while I suspect these benders would be fine for rod, I bet bending tube might be tougher without kinking it (or filling it with sand to act as a mandrel). I was thinking of getting some rollers like War Pig used to help support the tube. That being said, do you think bending rod would require a supportive die? I'm planning on 5/32" rod for my next cage. After I design my bender in Pro/E I'll see about posting up some pics. |

Tommy R, You shouldn't need any supporting die just to bend rod. The biggest tip I can make when bending rod is to get the travelling pin as close as possible to the pin that you are bending the rod around. This way you get a more precise bend and not a sharp bend followed by a slightly arcing straight section. When the travelling pin is to far away from the center pin this is often the result if the forces to make the rod bend are high enough. You can always straighten out the arcing section by hand but I like things to be precise from the start. I'm with you on not having to use sand to pack the tube, why make it more work than it has to be. Fastball |

Here is how I bend tube. 2.5 x dia radius, 3/16 tube, same result on mild steel, stainless, chrome moly, brass, same results every time. Fastball |

Very nice!! Would you be interested in making/selling a few of those pieces (or all of them)? If so, please feel free to PM me. Very interested.
