what do you think...

[rehab]

i scratched a drawing out on some paper today for my buddy to bend up some tube, just want to run it by you all first to see what you think.

the mid hoop will sit right on the B piller (pic got a little out of scale) but the triangulated bars in the back will still allow for the rear seat to be used. i really would like the rear seat to still be functional since i i drive it on my up north trips with all my gear and buddies. so what do you think

top view

oh yeah and its not like im racing it or anything, i just want to be protected my self and the stucture of the jeep incase of a flop or tumble down a hill, and 5 points will be going in also.

have you thought about bracing it to the frame, or are you just going to bolt it in and hope it works... also you might want to read about different ways people have welded the cages together, because inside the rig its really hard to get good penetration all around when the cage is inside...

and my only change would be

 

[rocklandxjer]

so you can recline your seats yet keep the rear functional. also id add some gussets to all of those joints. if you really want to protect yourself, and not just "have a cage"

I would make sure you have enough helmets for all occupent...

With all thos eabove cross bars and the b-pillar X being right where the heads will go...

Might want to search some more and see what others are doing in a XJ?

 

[rocklandxjer]

i was thinking something like this for your b pillar and cross bar.

and if you insist on these

i like this idea and i was just planing on welding and bolting the cage to the unibody, im not really sure how i would go about tieing it into the "frame".

What program is that? Nice drawing.

Simple autocad will do that..

Pretty much exactly what I did.

If you want that hoop on the B-pillar, you need to have it bow out like that, otherwise your seat will be up against the steering wheel.

For tying it into the 'frame', the commonly accepted way is to have plates bolt through the floor:

^not real bolts

and then those plates get braced into the reinforcing on the unibody rails (the blue angle stuff, but cage plate isn't tied in yet).

I also did the dash bar like you've got pictured, you can sorta see it here.

 

[rocklandxjer]

simple autocad did do it.

autocad 2006

id use inventor, but i dont have it at my house...

 

[rehab]

i know for a fact if you have autoCAD LT it wont do 3d models, just FYI

 

[rocklandxjer]

autocad lt is autocad lite. an intro, i think they like give them out for free now.... autocad (insert year here) is the actual program. and if used with the right amount of knowlege, and patience, its a fairly powerful program.

but no where near as powerful as programs such as inventor and solidworks for ME and Revit for architecture.

its a fun program to mess around with and if you put enough time into it you can make really great designs

 

[rocklandxjer]

i love the way autocad looks when materials are added and its all rendered...

Yikes! Hope I'm never one of the guys sitting on the sides of the table with NO legroom!

ps. that's a bitchin fridge you got

 

[rocklandxjer]

heh heh

its an old drawing i did for class one day last year. just showing the rendering.

all my actual design drawings are at my computer at school...

and yes. the fridge IS bitchin! lol
the sad thing is it looks pretty much lifelike to the one i have at my home...

I dont think that is safe at all.. well you sid your gonn tie it into the sleving and the unibody.. That would be ok. why do you want to unbolt it? if you dammage it that bad from a roll the whole XJ body will be a loss. Welded is better then boltd IMO.


I made this one 2 years ago..

Run the tube through the floor so you can drop it down to finish all the welds on the top.. The 3/6in box connects between the sleved frame rails and the 250wall sliders..

you can tie it into the seatbelt sholder strap mounts...

Yeah I am DEFINITELY not leaving it like that. All 8 points in the cab will be tied into the unibody...probably with pieces of the 2" x .25" wall tube I have left over from the lower links.

It's not so much that I am wanting to unbolt it - chances are the whole thing won't come out when it's done anyway. I built and installed it in sections. Being my first experiment ever with tube I didn't trust myself to be able to build it good enough without having it sit on the floor, and this was a better solution than trying to drop it down as far as what I was able to do.

This way also integrates the floor into the design, and helps keep the floor panels from pulling up away from the unibody rails (I've seen this happen). With 32 grade-8 1/2" bolts holding it together I don't think there will be any strength issues compared to welding it directly to the rails really.

Just an update because I got something done on it. This look better?

Boatsides down the length of that too.

Is that 120 wall 2X2,Thicker box tube has more rounded off corners...
Did you weld it with stick?
