rollcage question

I am fabbing up a rollcage. I was wondering between the front and rear hoop where would be a good spot to tie them in together. I got some pics of my current progress. I just want in agood spot so I don't hit my head on them I am six foot tall so anything impeeding me climbing in and out of my jeep is not good.

 

I'm not a pro at building roll cages, others might be better to explain strength at different points, but I've seen a lot of jeeps with the bars positioned at the inner edge of the seats. This would appear to be a compromise for head room.

 

Here's a couple of shots of mine

 

I'd put a pair on the outside and learn to duck. If you wheel anywhere near trees, they will tend to get hooked between the hoops.

 

Hi, the strongest place would most likely be putting the spreader bars out at the corners. It's harder to get in, but the point is that you are "in" the cage. I have seen some front hoops that bent in a roll that didn't have supports tied at the corners. A friend of mine came up with a compromise style for his jeep. He bent his two spreaders in a long arc and was able to join the cage at the corners for strength with the spreaders joined in the middle to strengthen each other, and still have it open above the doors to get in and out better. Not sure if I explained this well enough, I'll try and draw it below...

Well, I am not sure if that helps, but imagine that is a view from the top of the cage, the solid line up top is the hoop behind the seats, the dashed line is the hoop at the windshield, his spreaders had a gradual arc, and swooped between the cage corners and met in the middle, nice design for him, because he wanted easy entry and exit, and it also keeps the cage supported at the corners. Hope this helps.

I had a cage with inboard bars overhead, It was easy to get in and out, and Im 6'3. however, I would take into account what these other guys have said. I have gotten basically immobilized on a tree more than once. That involved basically winching the jeep completely sideways up the side of a gulley. More importantly, on a pretty serious endo rollover, the bars completely collapsed. It was the fault of both engineering, and welding, and it was completely destroyed. The problem was, that when the jeep went back wheels over front, the whole cage deflected off to one side. This was welded by a pro, but not properly tied to the frame. Bottom line, in a serious rollover, I think that even if it was tied properly, the design was poor. I would definitely recommend triangulating, or at least putting them as outboard as possible, and useing angles, or bends to keep the bars outside of your head. That was what I learned after a night in the ER, and a friend whos finger tips are finally starting to resemble real fingers. Not a good situation. The one coming out of the creek is the new one. Much better IMO

 

i like the way dennis has his, that is how i want mine to be done, i think it is the least bothersome....... my .02

 

It all depends on what you are doing with the Jeep. For everyday use, the bars like Dennis' work great, and I like the way it looks. Just remember if you are wheeling the jeep and that risk for a roll is always there, that is an inherently weak design structurally. No offense I had mine the same way cause I liked the way they looked. Its a form/function thing for everyone.

 

I mounted mine outboard for head room in front as well an in the rear, I am 6'1'' 280 so room is mandatory the rear bars were moved outboard also so my kids would not hit there heads I still need to cross brace the front and rear from side to side as well as a brace to triangulate the cage hope these help.
