Hi All -
Once more, apologies for any repetition (also posted on TOL).
Proposal: To weld M12 nut on to the upper rear shock mounting brkt. Bolt will be accessible from road wheel side.
What d'you all reckon? Any likely probs?
TIA
Dick
Thats what i did on mine,no probs
Thanks for the confirmation.
Dick
I mounted my rears at an angle, that way i did'nt have the problem you describe, tops inlined toward center line of car..... 
That's an excellent idea!
BTW I've drawn up a panel which goes right across the top with the suspension mounts on each side and mountings for 'cobra' hoops. Merlin can cut
them on the laser if anyone wants one - I'll post a pic in the photos area.
Chris
Interested in the panel as I'm intending to use Cobra hoops. Let me know a cost when you have it.
Another question as it wasn't answered b4, disposable argoshield gas bottles or rent a large one? Not sure how many of the smaller ones I'm likely to
need, and if it's worth shelling the extra on a rented bottle???

According to the info I have the CO2 does last twice as long, but according to a few on this forum argoshield is much better, tho haven't tried it myself yet, and as I've only just started welding I don't know if my welding is any good anyway (though it does seem to be getting better!)
worth a try.........know any local engineering firms ? they may loan you a bottle for the cost of a refill ? the smaller family, car loving place is
the one to try.......

I have used the co2 you get from pubs for years it cost me £5 a bottle lasts for ages
My local welding shop will do a pub sized bottle of argoshield light for £24 + £37 annual hire, which seems ok. as I know know any local engineering
firms... Even said to come down and they'll give me a few lessons! Apparently there's a video on mig welding available on the net, tho' I haven't
found it yet, if anybody does, let me know.
Cheers

Personally I have a 'no gas' welder. Yeah, yeah, I know you lot all slag them off but I think it's great. No messing around with gas bottles and
regulators, just plug in and go!
Chris
Jasper, and anyone else who is beginning welding, if anyone offers you lessons then accept, take your own welding equipment (and some cut pieces of the 1" RHS) and let them show you how to adjust it. The thing about videos etc, is that the video can't watch what you are doing and put you right, and can't set your equipment up, a teacher can.
have been welding for years (although I don't claim to be a professional!)
a few tips -
The thicker the metal, the higher the ampage and the slower you move the torch.
When welding similar guages always point wire at the join.
Although welding vertically always gives a neater result it can be a weaker weld.
Always set up on scrap!, choose the amps you want and then adjust the wire speed to suit (until it stops 'spitting' - If it pops and spits rapidly
then the wire speed is too fast!)
If you are welding thick and thin together - ie a 8mm plate to 1.6mm tube always weld bias the thicker and 'flick' onto the thinner (set welder for
the thicker).
Lastly, if you see a definate 'shaddow' around the weld (seen more when painted) it is a cold weld and has not penetrated! DO NOT weld over it, clean
it off and start again!
Hope this helps....
Cheers for the tips. Spent an hour with the metal fabrication firm that I've got my Argoshield from this morning, really nice guys, taught me loads, and set up my machine, invaluable. Found out I needed far faster wire speed to what I was using, and now it's buzzing beautifully!!!

I plan to use cobra hoops as well... I used a 1"x3" piece of stock for the "O" tube.
I recently assembled this part of my build and you can review the pics in the "assembly" section of my website.

Hi Chris,
I just checked out your roll bar hoops panel... nice laser cutting! Will the hoops extend below the plate and mate to the chassis down below?
Are you going for looks, or will the roll bars be functional as well?
Cheers,
-Jim M.
Not decided how functional they're going to be yet - had just thought I'd make them out of exhaust tube and get it chrome plated but I'm starting to
change my mind. If so I'll probably do what you say and have the hoops extend right down to the bottom which should put enough strength into the
panel to use it for the harness mounts aswell.
Any suggestions for getting the tubes bent to shape?

Hi Chris,
sorry for delayed reply...
Regarding bending roll bar tube, the first question might be what material you're trying to bend. What I've seen (and I plan to use) is 1 5/8" OD
chromoly tubing with at least an .065" wall (16 guage in the states) or .083 (14 guage). That will hold up to just about anything. I would not
consider muffler tube for anything structural... it is usually very thin-wall in comparison.
Of course, the real question is bending. I'm fortunate to have a friend with a professional rig... but I recently found a company on the web that
sells pre-bent tubing specifically for roll cages.
http://emporium.markwilliams.com/prodlist.asp?catid=1063
They sell a variety of pre-bent tubes, but SKU 36100 or 36172 might be spot on. Their paper catalog has more measurements, but their site has better
photos. I'll let you know if I buy one just for fitting, photos, etc.
Cheers,
Jim M.

LoLo is a No no! As I've said before, I'm not buying anything from them again!
Hiring a tube bender, however, does seem like a good idea. I'll look into it.
