Worked with a friend of mine to model this up. The dimensions are close but nothing to cut by.






Things to still be done that I don't know that I'm going to change on the model or not:
Shoulder harness bar
Straighten the A-Pillar (but that will for sure happen because not having to bend that is going to be awesome)
Move the 'ladder' step on the b-pillar up to meet the bend on the bend and also match up to the shoulder bar
Dash spreaders
Seat mounts

I've been toying with the idea of putting a diagonal from the B pillar to the top of the C pillar like you drew, minus the box. I was wondering if this would help protect my 2 year old better. I have the rest of the cage cut and ready to be welded in, but I haven't decided what to do. I'd rather protect him then myself if something happened If some one could tell me why not to do this I'd put it in the traditional way.
I'm using the stock cage and adding to it.

I was asking my engineer about this as well and said that this is going to provide more rigidity for the rear portion if the cage especially in a backward roll. Your design with a straight line is stronger than mine but mine will allow more room for people and that horizontal bar acts as a ladder step.

OK, I finally got back into BendTech after not messing with it for a couple of years. I can email the file with my complete cage (thank me!) to you or I will provide the pick points I used here below. My center point is directly between the B-pillar floor points--everything is based around that.

A-pillar right: X37.5, Y-25, Z0
A-pillar left/drivers: X37.5, Y25, Z0
B-pillar right: X0, Y-25.188, Z0
B-pillar drivers: X0, Y25.188, Z0
C-pillar is where factory TJ is...I would move it back 3-4" if I did it over
C-pillar right: X-37.5, Y-24.125, Z17.9
C-pillar left: X-37.5, Y24.125, Z17.9

All of these points are the center of the floor plates.

For added value, my b-pillar and a-pillar function as the factory one does allowing window surrounds, full doors, seatbelts, etc
I will also say that it took me literally months of tedious measuring and remeasuring to get all of this data in bendtech.

Question on average how much steel are all of y'all using for your cages? I'm starting to figure prices of everything now.

That is beautiful! I really really like the gusseting and the way it is done. Lots of attention to detail.

Trent,

I did 2" for main A,B and C pillars and their cross members and 1.5" for everything else (and a bit of 1x2 rect tube for the seat mounting)

2) 20' 2x.120" DOM
4) 20' 1.5"x.120" ERW

I am not positive (age related memory loss) but the DOM may have been 18' long sticks

Trent, be aware I think he was saying 2x20' sticks of 2" and 4x20' sticks of 1.5", though 120' seems a bit much?

Correct, I made fenders, sliders and mistakes too With the 4 sticks of 1.5". The cage has lots of triangulation and is tied to frame. It is in this thread way back in January I think

EDIT: I just went back over the thread and in #914, I said it took 6 pcs of 1.5" tube. Good thing I write this stuff down. LOL

So, way more 1.5" than I thought. The cage I built back then was my first cage and first time using a bender. Lots of wasted material. One mess up became my front stinger, so I was able to "adjust" some of the mistakes.

Beat it to fit and paint it to match!

Thanks! Looking back, there are a few things I would've changed, but it seems it's all to combat a worst case roll over at high speeds. Door bars I really wanted, but climbing into a 2" lifted jeep with daily driver suspension seats is annoying enough as is.

I ordered 88' of 1.75x.120 wall, not including the front Synergy Suspension cage. I don't think I have over 4-5' left. The calculator I build said the design required 80'. My buddy told me at the start of my cage 100-120' feet was his average for a full blown triangulated cage. If you include my Front Synergy Cage, I was right in that ball park. Door bars would've added 10' to my total.

Shoot me a PM, I have a calculator for all of my estimates for tubing orders and organizing the cage build. I have attached images of my "Assembly Connections Sheet" that fed a summary sheet.

I hear you on the door bars. In the back of my mind, I have a small plan/idea to do a tube door/bar get-up that will tie/hinge to the A pillar and bolt/latch/lock on the B. I may never get to it, but I did start it using 1"x.120 structured up pretty nice. Just sitting on the shelf rusting.
