I started my build with the obvious step of removing the factory roll bars. This was not as easy as it sounds. A couple of years ago, I herculined the inside of my jeep and I covered all the torx bolt heads and plates with that stuff. It took a long time to dig it out of the bolts and to cut it around the plates. I learned a lesson that day. Remove bolts before hercing. I also learned this stuff is tough.
Once the roll bar is out of the way, measure how wide you want your B pillar hoop to be. Remember to leave room for plates and leave a little gap around everything like the door latches and in the corner where the plates are. Take your time on this step because everything else is build around this hoop.
Thanks to Terry, I learned some new tubing tricks. Here is the first couple. It is difficult measure the legs of hoops because the top of the hoop is 7” away from the leg. The easiest thing to do is place another piece of tube to give you a spot to measure from.
When you bend hoops, it is almost impossible to be perfect. Most of the time your hoop is wider at the bottom of the legs then at the top. Use a racket strap to stuck in the width.
Once the hoop is complete, I went to work on the B pillar plates. Here was the plan: have a plate on the bottom side of the boat side rockers with a piece of 1.5” DOM tube welded to it. The 1.5” tube would go through the rocker, floor board, and top plate. Bolts (1/2”) would hold everything together.
The first step was to make the top plate (the one that sits on the floor board). It was drilled with 1/2" holes and a 1.75” hole to allow the 1.5” DOM to pass through it. The top plate was placed inside the jeep and used as a guide to drill the holes on the floor board, rocker, and bottom plate.
The rocker was drilled with a 1.75” hole and spacers were welded.
