Title: Helmet bars with a 5 point cage ?
Post by: PSweeney on April 28, 2014, 02:58:18 AM
So how are you guys doing the angled bars in a 5 point cage ?  My chassis guy put right angled bars in on a 3" radius bend and they annoy the heck out of me.   Are large clr dies available for 1" tube ?  should this tube be ring rolled, or sand mandrel bent ?

Larger CLR dies are available, just a matter of spending the money. You could also use the existing die and bend the bars to something less than 90 degree's, lets just say 60, it gives the back of your car a less "squared off" look

biggest CLR I've seen for a JD2 bender was 5.5".   I reckon for a continuous bend I'd need a 7-8" CLR ?

I did consider less angle but on a 3-4 clr the straight  legs after the bend would join the cage vertical uprights at an angle.  I'd like them to be meet square so the bars flow without any sharp angles.

I agree. Some cages they look good, others not so much. A 6 point cage seems to be able to get away with it a little easier than a 5. If the car I'm building has a single bend shoulder hoop, I roll a 1" tube on the same clr, cut and fit it to the back bar on the 5 point cage and it comes out looking nice. But I also realize that not everybody has a 3 roll bender in their shop.

Neil and parks sells a 8'' radius helmet bar I used them on my 5 point
