Roll Cage

[makeitfit]

Oh yes, always thinking :thumb2

Looking good but are you not adding a x in the roll hoop?

Not on this one, just a single diagonal from drivers head back :thumbs There may be some lower struts going in if I get time.

:thumb2 Driver will be plenty safe then :lol

When everything has settled down your end how much would I have to pay you to make a roll cage for mine?

I'm not sure yet mate, learning as I go . I need to experiment further with this bender to see if it's even viable.
Even so , it's cheap enough to get the tightest bends done for me.
I'll update you as and when I get done :lol

Its very cool, but is it necessary?

I guess more so for a short wheelbase as most of you guys are 2 seaters only :nenau

Yes he needs this Alex as Pete needs somewhere to attach his 4 point harnesses to:augie TBH a internal roll cage could easily be made up for a LWB but getting into the back seat could be a bit tricky depending on the design. The back seat on my LWB almost never gets used & i'd love to take it out but the missus has said no:doh

You can always go with an Exo frame, one on the outside, like some LRs, Alex has already made a start on his.
I can see the advantages of an exo frame, when going to supermarkets lol....from door dings...:doh

I wish mine had an angle iron skirt that came up from under the sills when you remote lock the doors.:augie

 

[elty001]

I like the idea of an external frame.
Done quite a bit of digging into what is involved and how they fit on a lwb and still keep the rear doors functional.
Have yet to find one fitted on a terrano but there must be one out there.

Looking good Pete

Look forward to seeing it in May :naughty

Only 3 weekends left:thumb2

Oh fook

But the cage is progressing

Top day at the welder :thumb2 Started off lining up the spreader plates

They needed trimming a bit to suit my rather interesting floor terrain .

Then it's back to the magic bog roll for some angle ometry This is the 1st diag support.

After a little fettling with Mr Grinder I got this :thumb2

Then plug in one son and weldering he goes :bow
Base plate to upright weld :naughty

I cleaned up the wheel arch ready to receive extra strengthening plates for the diag

Put another 50p in the meter and off we go again.

I made up a buttress to shoulder the diag like this.

and the boy showing off his penetration

Then I set about scribing that to the arch like this

Oiked out the side window so we could get a good look at the intersection and weld it.

Tasty

That's about as far as we got tonight. Much fabricating done though and loads of extra strength welded in.

Hope the rain stays orff tomorrow and we might just get there :clap

 

[makeitfit]

What a stonking day A bit of a lot of wind so we did have some winnbreak action going on but managed this lot
Same routine, bigger bits . First diagonal in.

The other half of the diagonal is a bit more tricky to get just right, but I've got the hang of my bog roll now

The last bit in and no pressure lol I had about 400mm left over No returns if this didn't work out !

Here's a little detail of the boy's welding :sly

Detail of the diag to strut join . No idea if this is MIA CIA or whatever legal but we love it :clap

Now working on the under body plate and chassis strut . There will be a bit of cow mat in there to absorb vibration and avoid body cracks I hope.

Just need to work out a way to hold the spare next , but at least 35" fits, just

Cracking cage Pete, my only criticism is I would have taken it to contact the roof so in the event of a roll it would limit the roof jamming the doors, you may of course be planning on doing this anyway at the sides/top so as not to interfere with the roof escape hatch, but very nice job anyway, I would feel safe in it, Rick

 

[makeitfit]

Thanks Rick, now you point it out it makes perfect sense. I hadn't thought of that. I do want to reinstate the head lining and interior trim. So maybe a bolt in insert to the roof over the B post would be a good idea ?
Escape hatch is ofcourse clear :lol

A quick question, It appears you are fixing the body to the chassis, and the Roll cage to the body, then chassis.
But do you still have the rubber body mounts between the body and the chassis?
As if that was the case, I would expect metal fatigue around the welds around the mounting plates to the body, as the remainder of the body is free to vibrate because of the rubber body mounts.

Would you be better using solid chassis to body mounts, or do you have that already?

I am no expert in mechanical engineering, but just a thought...

I have seen similar vehicles where the roll cage went through the floor with a gap, and some rubber seals, and the roll cage bolted directly to the chassis, so there is no physical connection between the body floor and the roll cage or chassis.

Nothing fixed to chassis mate all to body, Rick

Yep sounds good to me, Rick
