Hey guys,

It's Shane from Baileigh here in Wisconsin. As you know, we deal with the Racing crowd on a daily basis and would love to get a little more involved on the board and help out in our area of expertise....Tube bending.

So, I will start this tube bending thread. If you have any questions about roll cages, bending tube, what the tightest you can bend 1 1/2" tube, application issues, what wall thickness will work or not, wall thickness vs. center line Radius or what material will bend, home made tube benders, home made dies, counter bend die positioning, true radius cut dies, vs elliptical cut dies.

Pretty much anything related to tube bending......ask away. We are here to help.

I have a stupid question. What tool is required to make the roll/radius at the top of a typical Dirt Late Model Door? I've always wondered what the best way to do that is or how it should be done.

Thanks,
Chip

Do you have a picture? I can tell you in a second what type of machine was used.

That is more of a sheet metal break tool than a tubing bending tool. A lot of your breaks have the ability to set the top part of the break back 1" to allow for a radius tube to be used that will put a roll at the top of the door. You can create the same type of effect by putting 3 30* spaced 1/4" apart.

Shane, he is talking about the area where the top of the door attached to the chassis

Chip,

There are a couple of ways to do it the most economical way is to clamp a tube with the correct radius that you want to achieve to a table with the panel under it and bend it around the tube.

Second there are a couple of options out there for doing this application with a brake

There is a video of how the last one works

How do you get the cheap benders to work without caving in the pipe?

The bender we have destroys chrome-moly. It doesnt matter how thick or thin. What bender is the most affordable that will do a nice job on crome- moly?

I have always went by the rule of thumb for minimum bend radius to be 4x the outside diameter of the tubing. ex., 1.5-in. tubing min. 6-in. radius. as not to stretch the tubing too thin at the outside of the radius. I build cages for cars that need to pass SCCA and NHRA inspections and have never had a recall. Is my rule of thumb correct?

Sorry, I went to your website and saw you did breaks and overlooked your question. My bad.

Whats the most economical tubign bender for the average team that yields flawless results? also not bending but notching same question? need to be able to reproduce the same bend and notches every time with measurable 3 axis measurements. tahnks in advance

What size tube? What is the wall thickness? What kind of bender is it?

First, decide whether you want a manual bender or a powered one, then the next question is about the operator. If it is going to be the same person running the machine all the time then there are a lot of economical choices that could get you by.

Manual
With these two make sure that you get the degree rings for accuracy
http://www.pro-tools.com/105.htm
http://www.jd2.com/shop/custom.aspx?recid=1
This one includes the degree ring as part of the bender
http://www.bii1.com/benders/manual-tubing-bender-050.php

Hydraulic
http://www.jd2.com/shop/custom.aspx?recid=6
http://www.bii1.com/benders/tube-pipe-bender-125.php


But if you want it to be foolproof and get the same results every time, you need to go a little more higher end and get something that has either and auto stop for the end of the bend or something with a programmers on it.

This is the same machine that Mars Racing, Mark Richards Racing, GRT and Bernheisel Race Cars has
http://www.bii1.com/benders/tube-pipe-bender-rdb250.php

As for notchers, again there are a number of choices out there. It comes down to the cost verse benefit of it.

The jd2 is the best bang for the buck in my mind. They also have bend software that is free to download.

Right on Jim, looks like you have been doing your homework.

Anyone ever wonder how to figure out how much tube is consumed in a bend?

CLR (center line radius) x degree of bend x .0175

Can try these two places for benders aswell. I made my own upright bender from some pro-tools diagrams I found online.

Also Cliff at http://www.tubetek.net/ He can make you dies in any style you want and makes benders.

Tons of people build the got trykes bender.

It indeed is a great buy, but one thing to remember is that if your working with Chromoly, it can be a finicky metal. It has a tendency to do things that DOM does not.
Who ever you buy from, call and talk to them to make sure that you are getting the correct dies for the application

Also keep in mind that tube bending is only as accurate as the material being bent. Most bend accuracy problems are because of material differences, such as different mill runs and different mills.

I use a Pro Tools manual bender. It has heavy solid steel billet dies and makes perfect bends! I have owned this from about 1991. It was in my budget at the time. (cheap) It could never wear out or break! I am happy!
