Hi all, can anyone tell me if they foresee any probs making my wishbones out of stainless ie is it to hard and likely to crack under stress over a period of time the welding is no prob as im a llyods registered welder also would like to use poly bushes so what id is best to fit them

No answers, prob everyone scared too stick there neck out, I'll risk it.......

I made stainless wishbones, rear trailing arms and panhard rod, they all performed fine for me, i made my own bush's, its that long ago cant remember size but i reamed tube out to suit.

When i welded them up i did purge them, i seem too remember a big discussion on that too, not sure its necessary to do this but i did anyway.

I could find and scan some pics if you wish i have no digi ones.

I polished them too a mirror finish on a mop with soap.

Rgds Jon.

grade of stainless is all 316 got it all from work (shipyard) went bust a couple of years ago but has since been bought and reopened and its all from stock that has no paperwork so cant use it on ships, to do with insurance from Lloyds i believe but i can use it on my car tho
Unfortunatly i cant do anymore dont think boss would be too pleased didnt mind me having some but "dont take the piss" were his words

Look really good!

I'm slightly concerned about the strength of you lower wishbones though. The area where the BJ bolts too is just a bit of plate where it joins the arm tubing.

You sure this is strong enough? There's a lot of strain there.

Cheers,
James


jester241uk - 3/10/05 at 03:31 PM

James , i dont think it will be a problem the plate is 6mm thick and i made the plate bigger then slotted the tubes so it sits inside them the tubes are 5mm thick ,welded continuous all way round, so i think the part for the ball joint should be ok, thanks for your concern tho

cheers

you shouldn't use 316 it will crack unless you take it and get it anealed.

304 is what you should use for stressed parts

Very much agree so many different types and grades of "stainless" that you have to check out the correct procedures for the type and grade you are dealing with.
With stainless steels pay close attention to the design of the wishbones follow the general pattern of the design used by GTS or the current MK type.

Oridinary plain mild steel is by far the most forgiving engineering material anything else requires careful consideration before using.
