Sprint anti-roll bar

[ardee_selby]

What Ralph & others have said wrt spring steel.

Nothing to add really, except:

"?200! For a bit of bent steel!"

?10.00 for the bar stock and ?190.00 for the processing....?

For example, if the material is EN45, you can see the sort of temperatures involved here: http://www.westyorkssteel.com/EN45.html

Also, isn't the tooling (used for forming ARB's and such like) designed to avoid surface damage as far as possible?

Localised heating plus any gouging/nicks introduced by correcting of a sett by clamping in a vice, say, wouldn't be good....

Cheers - rd (Let's hear it for all those heat-treaters & forgers out there!)

Dont compramise, last thing you need is the arb snapping in the wrong place & digging into the road surface you might need more than one set of pants! Also got a spare to get you out of trouble from my s2, Curly 1964 26Rr

Hi All, OP's other half here. To be honest, I agree with the consensus on here regarding not attempting to fix the ARB ourselves. I know nothing about the behaviours of metals, but it strikes me that anything that any attempts at straightening the ARB would be somewhat futile. So a replacement is definitely in order. One of things we've started to learn whilst working on the car is that making the car safe is paramount. As we've started to get to know it better, we've uncovered some things that were in a dubious state. As Dave quite rightly likes to drive the Elan in a spirited way, my aim is to make sure the car is in top fettle and in this particular instance, it doesn't seem worth attempting a DIY job on it.
Thanks for the very kind offers of spares - most kind and much appreciated!

If it "snapped",where would it have to snap to dig down into the road and pole vault???

Surely it would have to snap in two places at the same time??

Hi John, just after bottom shock mount happend to me in a plus 2, caught raised drain cover twisted chassis where mounted made me breathe a bit heavy & with all these speed humps we now have the potential is even higher Curly

Jumping Jesus, not another 26/R thread?

Nope if it was it would be a 26Rr thread Curly

Although my suggestion of re-setting the twisted ARB has been shot down, I'd like to qualify it by repeating that I suggested using a Workmate, which has wooden jaws & doing the re-setting in a cold condition.
I made no mention of using any form of heat.
Ref. the costs; any manufacturing process involving heat treatment does bump up the cost considerably.

Nix f?r ungut.

They are spring steel John... I tried to ''re align'' one from one of my +2's, and even with it held very firmly on a solid bench with a 6" vice with ally grips, and a large tube over the 'moving' end. No Hope! I suggest you go try this.. It is one very strong bit of bar, and my one just returned to where it was. I had lots off effort on it and was hardly able to move it! I am not a 'small' guy either & I was hanging off it.

Hope you are progressing with the 26 R (r)eplica Colin (Curly) Haven't had a report for some time. What stage are you at?

Use a Sep' post and tell us all about it. This should help stop Peter from having another Palourie.. If you care!

Fair comment & taken on board Alex.
Wot I writ was a suggestion & not based on experience; in retrospect the "Simples" remark I made can only apply to the theory & not the practice.
Nevertheless the mind boggles at what forces were at work to cause the twist described

My apologies for having mislead anyone into believing this was a simple problem to resolve

Cheers

Yep! It payed my mortgage for a while...until I got sussed!

But, das auto ist so gut wie nichts wert, without it

Considering the amount of effort required to reset the roll bar it makes you wonder how it became twisted in the first place

I don't think we're looking at a one-off event. We don't know, but if it's the original ARB with 40 years service, seeing cyclic stresses and material creep, it's settled like a conventional road spring would.

I expect it is the original - the shocks and shock bushes certainly looked it - although the trunion bushes were replaced with poly ones and the drop link to ARB bushes look pretty new. Hopefully it is just usual wear rather than an event causing it!

Alex I dont understand your drift about Peter perhaps you could explain in simple clear & concise non cryptic words CC
