Re: CJ-5 cage tie in Q
That's probably a good idea. You often see that setup on race cars.
Anythings better than nothing in the frame tie in , but it's hard to do. You just do the best you can with the constraints imposed on us by the wheel well, frame width, etc.
There are typically outrigging curved tubes (J shaped) welded to the frame at the rear. Problem with that design is that tubing has it's best strength in compression, so straight tubes are far stonger. But a straight line from the rear most bar on my jeep would put the end outside the frame. I see those cage tie in kits sold in the catalogs, and I picture how weak it must be to have an angled roll bar terminate on top of a verticle tube. Any impact would simply bend the vertical tubing, something which it has little resistance to. I think if you wanted to build the cage really strong, you could have to triangulate the cage to frame tie in's. Either that, or you are only building for an upside down pure vertical impact.
If someone has a good rear tie in design and could post some pictures, we would all benefit from your knowledge. Thanks.
