When I decided to build my roll cage I wanted to be able to make the welds to satisfy myself, be able to paint it and also to remove it and put it in another XJ just in case I ever had too much body damage. I decided to put some "connectors" in mine which would allow me to tack the bars together, remove them and weld them up outside the Jeep. The connectors have two 1/2 bolts holding them together and they are machined very closely so that the ends just touch each other. Those are not the bolts that will end up in it, just used them to hold it together while welding. Here are some pictures as I went. I will load the painted pictures later today and the installed painted pictures Monday. I plan to put it back in the Jeep when I get home today because they are calling for a little snow at Windrock tomorrow and I love to play in the snow!
