Cage design

Well a few people on the board seem to be designing internal and external cages and toob work. So I thought I would start a thread where we all could put some thoughts into. Now lots of people are going to have different ideas of what suits them and what they will like. So if someone posts a picture of an external designed cage I don’t want people bagging them coz it’s not their style. But feel free to discuss structural integrity.

Also talk about the size and type of tube you would use, or have used so that when someone decides to build a cage they can read this thread and get some idea’s of what’s best.

Just a question, I am about to build a cage that is going to be tied into the left over body panels and chassis. I am about to take the existing body lift out and when I do I’m thinking about solid mounting the body to the chassis. The reason for this is that the body will flex heaps on the stock rubber mounts. When the body is tied to the cage I think the welds will crack from fatigue over a period of thrashing. What are people’s thoughts n this matter.

Please observe forum rules before making a post.

I doesen't appear to of been built for strength but rather carrying objects (its a roof rack)

With no diagonal support nothing is truly "strong"

Hey mock how about you post some pic's of your cage. Also have you plated the chassis where you welded the cage on to spread the loads?

Are you making your own cage Dewse or getting someone else to do it?
After that guy died up in Lannos rolling a softy I'm rather keen to get some sort of roll protection in my bunky. Even if it's just a hoop along the lines of the targa bar.

Yeah Im keen to get some sort of roll protection into my missus zook too.

The previous owners flopped it onto its side and the centre pillar thing is a bit suss looking. It flexes quite a bit and I think has cracked around the screws that hold it together.

Im not sure to go a full internal cage or just a single hoop.
There are HEAPS of zook cage pics on pirate.

might be worth keepin tabs on wether the unit is for road legal or not to....

i know in QLD fittin a full 6 point in a zook is painful due to exit/enrtrance issues...

lookin to push the front connections down through the dash to the firewall (trash the air vents)...

Good starting place would be CAMS cages.... and yep, triangulate...

Planning on 2" thick wall black steel as material of choice, w mandrel bend. Fish mouth pipe welds and gusset, 50x50 plate top and bottom w' radius corners at body attachment points.

just my 2c rounded to 5, plus GST

Will be breif due to time restrictions..

in the interest of simplicity, but usefullness, start with a main hoop (red), and build off that an upper exo/brush rail that goes around perimeter of windscreen frame and entrance link member (that piece of crap I always hit my head on... :x ).
Similarly, a exo section which goes around the rear of the body which will absorb most of the side loads.

The only real 'structural element' of the cage is that main hoop, the 2 straight braces which go backwards to the rear of the body, and the diagonal piece strengthening the main hoop (all plated and bolted to body).

I did consider doing more barwork but when you start to compare ...

1. the C.O.G. and the mass of steel your adding (quite often with no real benifit..)
2. the total mass of a vehicle
3. the type of slow speed roll overs (depending on the hill ;) )

I feel content that this setup will be both user friendly, and suited to this type of vehicle.

I was hoping to finish mine before christmas (to look like the attatched) but have been to busy at work and with other responsibilities, so, will have to wait a few more weeks.

That’s cool drewfus! It’s very similar to what I am planning but the only difference will be that I have a dove tail and no roof/doors/targa/windscreen….. Well I lie my windscreen will be plastic and attached to the roll cage

This looks like what the cage is going to end up looking like:

So the new toy is going to be dovetailed, are you dove tailing the original body work or fabbing up panel work ala fatkid from pirate?

your photos are always so huge. perhaps you need to resize them, or take them with the camera on a lower res setting.
My pooter just about has a coronary opening them :)
