need some advice on chassis build

would like some advice on tube bender dies. gonna build a rock bouncing style chassis with ATV/UTV running gear. i'll be using 3/4"-1 1/4" DOM tubing. my question is for this pipe size what would be the best CLR/RADIUS dies, 3.5", 4.5" or 6"? thanks

When I bought my dies I read somewhere that the bigger the clr the stronger the bend would be because the tube won't stretch as much. But the smaller the radius the easier it is to fit into smaller spaces or keep it tight wrapping around something.

I've been wanting to make a small buggy like this for a while just have to many other projects I have to finish first.

For those sizes of tube, I wouldn't go bigger than a 4.5" radius. I've bent a bunch of 1-1/4" x 0.065" wall on a 4.5" die without a problem. My 1" die is a 3" radius and my 3/4" is a 2.25". Sometimes I've wished for a 3.5" or 4.5" 1" die because it distorts the tube more than I would like.

Check with your die supplier and make sure you do not get a smaller radius than they recommend for the wall thickness. The thinner the wall the larger the radius to not distort the material.
