You’ll have to narrow that down a bit, Brian.

Hi Steve, yes I read that one. The BMW ones are very expensive and I'd like to have a prepared replacement ready for the ones I take off, as I suspect they may crumble...

I have 3 or 4 I could sell you. PM me if interested.
They are used and have been shot blasted and painted.

His user name could be related to an engine which is an evolution of the British Leyland O Series, in 16 valve guise

Hello all.

Is there anyone on here knowledgeable on likely steel grades that the original rear frame fail safe washers would have been produced from. I have had a press tool manufactured and am looking to get an initial quantity laser cut, pressed and plated.

I have also produced an initial 2D file from reverse engineering the front and rear xenon level sensor brackets, as mine are really corroded. Looking to make these in stainless.

Hi Typhoon190
I am having the same problem as every one else!! I spent ages searching out and contacting several automotive washer manufacturers around the country without success. A set of shiny new ones that don't rust would be great (Phil B kindly has sent me some used ones to clean up), I always like to be prepared when I am doing a big job and have all components to hand to save time. Whatever grade of steel they are made in they are quite chunky and heavy! Please count me in if you start producing these!
Best wishes for 2021,
Bob

I’d look at a molybdenum grade of steel, they use that type in the manufacture of roll cages etc.

Although the thickness of the washer, I would imagine any mild steel would be ok.

I'm in the early stages of making a SS version of the Xenon front sensor clip (the bit that fastens to the lower suspension arm)

Be wary of using stainless anywhere vibration is present as it is prone to stress fracturing.

I've made a small amount of progress with these parts.

Prototype form tool for rear frame fail safe washers. Will hopefully get a sample batch of laser cut blanks cut soon.

Also got a few sets of provisional laser cut blanks for the headlight sensor brackets from 304 stainless that I need to form up.

I seem to have mislaid the old rear bracket that attaches to the rear upper arm, so hopefully I'll find that as a forming template. I also haven't got a solution for the bracket that attaches to the front lower arm at present, as I'm not convinced stainless will be the correct material. As I recall, this is a thinner gauge spring clip which will be quite difficult for me to form with the tooling I have available.

Looking at the old sensors that have come off my car, I don't think many will be fit to be reused. Genuine BMW parts are obviously very expensive so it will be highly likely replacements will be cheaper aftermarket parts.
