Roll Bar + Chassis Plate Help

[HandyAndy]

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

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.

There is tons of it near the garage Tatey !!! And I have some too.

Flyerncle saves the day again!

Just an update on the roll bar situation. I finished fettling down the ends so that it was entirely level and the outer edge of the each side of the roll bar was 26.5mm from each edge, which to my eyes looks bang on in the middle of the plates.

I've also cut out a 50mm hole in the middle of one of the plates for the roll bar to sit though, as suggested by Flyerncle and HandyAndy, to give the joint some extra strength. I'll be doing the other side tomorrow and then welding it up, to quite a while to do with my pillar drill, hacksaw and rounded file, if only i had a 50mm slightly oval hole saw .

Cheers for the help everyone.

aarrrgh its purposly like that because when you weld the cross bar it pulls the roll bar in!!!

you are meant to weld the cross bar on first then weld it to the plates.

sorry i should have mentioned it in a more recent thread as it got lost in the melt down

[Tatey]

I thought there might have been a reason for it being a bit too long . Ah well, make sure you let me know for next time eh

The upside of it is that i got to find out how good the new ceramic flap discs are
