So, here's a rough design for the cage that will be made for my Willys. It will probably change a little bit, but this is what I'm thinking. (1 3/4" tubing) I've got a few questions though! My design is based off of the common 6 point cage, very simple. But I don't know much about cages, so I've got some questions :-)
I've been wondering if it's better to have the b-pillar tube on both sides of the jeep be one piece of tube? (like I have in this design) or if it's better to have the a-pillar bar and c-pillar bar be all one piece of tube with the b-pillar being welded in to that? (if that makes sense)
Thinking about putting a connecting bar to connect the c-pilars (just above the tail gate area) but I'm not sure I want to do that, as I wouldn't be able to load anything big into the back of the jeep very easily that way. Does a connecting bar between the two c-pillars just above the tub line/tailgate add much for strength?
I'd like to get some triangulation in there somehow, but I don't want to turn it into a jungle gym. Any suggestions? I'm thinking maybe an X connecting the top corner of the B-pillars to the lower corners of the C-pillars. That probably wouldn't affect my rearward visibility. But it would limit what I could carry in the back, I don't know if I like that.
I will be welding sheet metal between the two bars that connect the b-pillar hoop to the windshield, so that I can mount my CB, dome light, and a few other things up there.
None of the seat mounting structure is present in these images. Rear fender wells will be cut to allow room for new seats.
This will NOT be a hard-core jeep, it will be a daily driver and a mild trail vehicle, not a stretched rock crawler or buggy on big axles and tires. But it will see offroad trails that are capable of doing with 31" tires. So keep that in mind with the suggestions
Suspension will be about 1" higher than stock, and tires are 31x9.5x15 superswampers. Cage will bet tied into the frame at all 6 points.
