Roll Bar + Chassis Plate Help

[twinturbo]

Take some photos so I can see what yar on about..

If I have a similar issue, I think I will just cut a hole in the plate and weld top and bottom.

As you can see the roll bar isn't located exactly in the middle of the plates.

Oh and before anyone mentions, yes i know the left hand CP6 is upside down....

Looking good,

Now if I was building another one and got to the stage you are at now I would weld the cross bar on next as mine pulled in loads so the bolt holes don’t line up by 2mm either side. Then weld the roll bar to the plates.

Sounds confusing hope you know what I mean.

I think i know what you mean ginge. Maybe i should stop fettling it now and get hold of a crossbar and hopefully that will sort out all of my issues, taking the lazy option and all

What has everyone made the cross bar out of?

[Bonzo]

If memory serves me right ( Roll bar down the pit at the mo ) I used a length of the bush tube steel, the 33.7mm OD stuff.

It was there kicking about & looked plenty man enough for the job

Looking nice there Tatey

with the triangualted plates you mention, i can,t remember which way they are placed but if you wait until you weld in parts D12 then offer up the CP7 plates (triangle plates ) it,ll be easy to see their orientation

I,ve used scaffold tube for my cross brace in the roll bar, not that i,m advocating finding a building site tho

I also did the same as Flyerncle, where as my roll hoop was sunk into CP3 & CP4.

Your chassis is really taking shape, nice one mate

are you fitting an Ali rear tub?

Cheers Andy, by sunk into CP3 and CP4, im guessing you mean the roll bar mounting plates? And then bolting it onto CP3 and CP4? CP3 and CP4 are the large chassis plates with the 4 holes in them and the suspension mount welded onto the bottom.

Oh and yes I will be going for an ali tub, hence why i ordered 2 x CP11 + 2 x SS1 plates from you last week

Hi, looking real nice there Tatey.
As for the cross brace, id bolt the plates to the chassis and weld the bar insitu then weld the crossbrace while its all bolted up then hopefully it wont be able to pull as it cools. you could also put a temporary brace between the suspension towers while you weld it up.
its normally as the weld cools thing start to pull.

Sounds like a really good plan Ray.

I just need to see if my mate can come up trumps with some scaffy bar now.
