Being that the vehicle only weighs something like 2400 pounds. I'd like to make it safe & secure, but I don't want to go over kill and end up with a jungle gym that isn't enjoyable/practical to drive around town in.





If you have the space to pull that off I think you will be golden. I was unable to do a X in the back since I didn't have access the a bender. For a flop to mild roll I think this design will be pretty trick. Planning on going a windsheild ^?

I'll just be leaving the factory windshield there, and strapping it down to the cage, with some rubber bump stops or something.

My factory cage with a front add on survived and saved my wife and i during a 60mph rollover, we rolled 3 times and walked away. Rolling a different way may have had a different outcome but you cannot plan for everything.

Jesus! This spring I'm planning to reweld and gusset / support my already modified cage. Stories like this make me prioritize that.

How did your seat mounts hold up? Any recommendations concerning factory seat mounts and seat belts after the 60mph roll? (Question not directly related to cage pics but relevant to everyone following)

Not into the gore factor, but can you post carnage pics so we can see how things held up ? What tore, ripped, bent ...

Sorry I meant a windsheild spreader from the lateral bars to prevent any flex in the event of a flop. Hope that makes sense

still not sure what you are referring to, sorry! Right now the plan is to have a bar going from the top of the A-pillar to the top of the A-pillar from driver to passenger side, right along the windshield top line.

He is referring to tubes that run from the bar you are describing (from top of A to top of A) down to the bar across the dash. Usually configured in an upside-down "V" like so "^" for triangulation and to spread the forces through the dash bar. They add a lot of strength to the front of the A-pillar and prevent the windshield area from deforming into a rhombus in a flop or roll.

Here is a picture from Google to help.


I would also suggest adding some triangulation to the overhead spreaders (tubes from the windshield top bar to the B-pillar) that currently run straight front to back in your rendering. That would help prevent the a-pillars from shifting left or right in a roll.

As far as the X in the b-pillar goes, it ads a substantial amount of strength to the cage in a rollover and helps prevent the b-pillar above your head from shifting. You have to decide what is more important to you, ultimate strength and protection or a usable back seat/storage area and compromise one or the other.

Your rendering looks like a good start though

Pretty much what Mike said thanks for the Google upload

Hossfeld Hydraulic bender!!

Well, I managed to get my hands on my buddy's Hydraulic bender this weekend. It is the coolest tool. I decided rather than jump right in and start messing up 2" DOM, I would tackle a few smaller projects using 1.5" ERW. I started with some rear tube fenders. I will put some diamond plate on them for a dual step/slider, this way the kid can climb in from the back. I made a few "bad bends" but I found other uses for them. When I get around to my front bumper, the stinger is ready LOL. I had a four year old helper this weekend. This is going to be great family project

here's mine as of now.

i still need to add a couple pieces to the inside, like harness mounts, seat mounting frame, and another couple pieces in the back .

and on the outside i still need to add a b pillar bar and then another bar to go from the bpiller to the rear pillar right under the back window.


as it sits now the cage is tied into 6 frame rail (adding 2 more), tied into 4 plates on the roof, 4 spots on the floor board (adding 4 more)

I am wondering why some put center bends in their A pillar like shown in the pics? Is it for a gain in triangulation?

THX!

I would think it's for looks. If anything it would hinder the tube's ablility to stay straight. I may be wrong here but a tube with a bend in it is more likely to bend in that area than anywhere else.

It is for the Angry Brow look. If properly gusseted they do not seem to be a major weak point, but un-gusseted would be a bad idea.

Actually I am glad it is for looks. I can skip it. The fewer bends the better for me, means less wasted tube! I will add the inverted "V" though.

Thanks for the help guys!
