CJ Roll bar / cage question

I'm mid stream trying to figure out what to do about my roll bar situation. Since my CJ is a 78, it has the roll bar that just sits on top of the fender wells. I can locate a later model CJ roll bar that goes to the floor. Eventually, I will add a full cage but for now, would it be worthwhile to put in the later model CJ roll bar that goes to the floor? Or better yet, use the later model CJ roll bar as a front hoop and add some spreaders. Has anyone tried this?

Re: CJ Roll bar / cage question

I'm not sure about your question exactly, but I have the early style roll bar which sits on the fender wells, and I have a full cage which is tied into the frame at 4 points. On mine, there is a 1/4 inch steel plate on the underside of the fender well, which is bolted to the roll bar. That plate is then tied into the frame with some tubing.

Re: CJ Roll bar / cage question

I'm curious if anyone has used a second CJ roll bar as a front hoop to make thier cage. If so, I'd like to know how well it fit.

I found a 92-95 YJ roll bar and installed it in my 78 CJ7. Perfect fit and I am now welding in a front hoop. The YJ bar also allowed me to add shoulder/lap belts for rear passengers.

Re: CJ Roll bar / cage question

This is my 79 with the roll bar on the wheel wells. I made a front and rear hoop and welded them to the stock bar with a few spreader bars and gussets. Welding a front hoop to your stock bar is fine. Just be sure you tie into the frame.

Re: CJ Roll bar / cage question

Looks good. I like how you bent the tubes out. I still have one last problem. I can't quite figure out the best way to notch the spreader tubes. What's the best way to notch them to get a good fit to the stock roll bar?

Re: CJ Roll bar / cage question

I'm using a vise to hold the bars and a drill press with a hole saw to notch the ends.

[/ QUOTE ]1. Ok, I can see the drill plress for fishmouthing, however,
2. How are you going to bend that tubing without destroing the radius?
3. I've heard of packing with sand, etc,
4. But that makes it almost impossible to bend with a vice.
5. I'm interested in this one... because I don't think it's gonna work... [img]images/graemlins/confused.gif[/img]
6. IMHO... it's better to have the tube professionally bent.

Re: CJ Roll bar / cage question

I'm bending this weekend..

I think what he's trying to say is that he's moved his vise, so it will hold the tube in the press.

The press and hole saw is exactly what I'm doing, only I'm using a little jig a friend built to hold the pipe at any angle.

That way we can get absolutely any pipe -> pipe connection perfect.
Just have to have a saw that will match the diamiter of the pipe.

Re: CJ Roll bar / cage question

The later model that goes to the floor is stronger, but the main deciding factor is how good your body is since that's where both styles of factory bars attach. You could have the best roll cage in the world, but if it's not properly secured to the frame then you're asking for trouble. Even brand new sheet metal doesn't hold up well to a roll, the roll bar tends to get pushed right through the floor. Whatever style you choose make sure to tie it into the frame.

Using a factory rear bar as a front hoop wouldn't work unless you could add some bends to it to conform to the shape of your windshield frame.
