CJ Factory Roll Bar question

I had my roll cage pieces bent, and I am ready to start welding it together. I plan to cut off the existing diagnal pieces that go down to the fenders, and replace them with the "TJ style" bars.

My question is if I cut these pieces off about 1" back from where they attach to the main hoop, is the main hoop a solid piece with no holes cut in it where the two pieces join? I ask because I was hoping I could grind it smooth and not see where they joined previously.

Thanks

Re: CJ Factory Roll Bar question

If I'm reading your post right, that is pretty much the same thing I did. Here is what it looks like. Note the extra metal on the rear hoops--that is to help with the mounting of the rear shoulder belts when I finish the seat and get the belts installed.

Re: CJ Factory Roll Bar question

Oh, I cut off the old "kicker" bars with a cutoff wheel on a diegrinder. I cut them as close to the main hoop that I could. (mainly I cut the weld) Then carefully ground away what was left, careful not to heat the main hoop up. For the welding....I must confess I didn't do it. Since my father is a mechanic and certified welder (coast guard certified for oil field work over water on tube and pipe among other things) I had him do it since I wanted the best welds I could get on a piece of safety equipment. Hope this helps!

Re: CJ Factory Roll Bar question

Thanks, I'm glad I just have to grind it smooth. I didn't want to have to put a piece in, weld it, grind it smooth.
Did your dad weld it under water? [img]images/graemlins/grin.gif[/img] J/K

My dad is welding mine too. [img]images/graemlins/smirk.gif[/img]

Re: CJ Factory Roll Bar question

Just be careful with the grinding, not to heat the metal up too much.

Naw, he didn't weld it underwater--though he can do that (he learned to weld 40 odd years ago in the navy, and has been welding ever since--he used to be a salvage diver).

Dad's are great aren't they? Sometimes I'm really annoyed at myself for waiting until I was in my mid-20s for noticing. Now at nearly 31, I frequently ask him for advice....don't always take it, but I do ask for it!

Re: CJ Factory Roll Bar question

I wouldnt cut them out. I would leave them there for extra strength. Have the bar on that angle adds so much strength to the cage. I would just fish mouth the new ones to fit over the orginal ones and go with it.
