Topic: To halo-bar, or to not halo-bar?
So, we've started the roll cage build. This is my first "from scratch" build. I've installed pre-bent/notched cages, figured this would be "more fun".
Main hoop is bent and fits great. John and I were thinking that we'd attempt to bend the a-pillar bars as a continuous piece that went from floor to main hoop.
I just attempted one, and it's quite difficult to attain 3 axis curves on a tube. My team mate feels that this is a bit safer, verses a "halo-bar" build.
Personally, I think a halo-bar with a-pillar uprights connected to the halo bar is an easier build, and will be just as strong. In my eyes; it's the same amount of welds, assuming that a upper crossmember bar is welded between the two a-pillar bars near the windshield.
Both of these assume that we'll gusset weld a-pillar at upper corners, and gusset bar to a-pillar of actual chassis.
What are your thoughts about this?
Thanks,
Tom.
