Also my two favourites 😊

Yes, mine too! Amazing work and attention yo detail.

YES when I discovered this channel a few years back, I HAD to binge it all. I still occasionally go back to view the epic Range Rover episode!

@@dan725 funny you should say that, I was just thinking that I might re-watch that episode too - 1 and half hours of delightful relaxation.😊

If you like the two, watch Jethro Bronner repair 105 series Alfa Romeos. I think you'll like it, he doesn't put out that much, that's why the algorithm tends to ignore his stuff, but it's excellent.

I was impressed with Ronald's restoration of the Fiero & the GPZ. considering he isn't an automotive channel.. ... Quite an inventive problem solver like George .

I was shown around some non purged food grade stuff by the guys at Delvo, I couldn’t believe the finish. Another commenter said they’d run a suite of analysis and tests and found that purged gained no more than 15% strength over no purged. It’s all very intriguing. I’m still looking for FEA help, but like you mean, I’d rather have the 15% than not ;)

​@@soupclassicmotoringAbsolutely impressed with your skills development.. Teach yourself FEA and you'll get an honorary degree from your local college. Rusty mild steel was still strong enough so shiny brand new stainless will be more than adequate. Original trailing arms would have been put through strenuous rig testing and track testing on finished vehicles way more strenuous than you'll ever put it through. All power to your elbow ignore the nay sayers.

Dunno, I’m appreciating the efficiency of design the more I work on it

I agree. The only good thing about using stainless steel for this purpose is that it sounds good to say it. Otherwise it's not a good idea.

@@bobolulu7615 so its better to not use stainless in order to want something more stronger right?

@@ALINUED Stainless Steel is not the "be all to end all" of metals. It has its place and automotive suspension systems is not that place. If you noticed, the original part is made of mild steel and is perfectly fine and has driven a few million miles on the vehicles without issue. When you talk about 'strength' , what is the strength that is needed? When it's in use on the vehicle, it does not twist, so torsional strength is not required. What forces are acting on it? Compression and tension. Over the length of the part, even these will have very few issues, there will be almost zero deformation of the part in compression or tension. Mild steel is very forgiving in this situation and the small deformations will be easily absorbed. Stainless Steel on the other hand does not like being changed and will be fatigued from this. If you want to strengthen the part, the only one I have ever seen or heard of fail, is the chassis mounting bolt at the front of the strut. It's about 5/8" necked down to about 3/8". There have been failures at that point. The original suspension link is more than adequate for its purpose here and the perceived idea that it will be stronger and make the vehicle handle better or whatever, is nonsense. Not one automotive manufacturer on the planet uses stainless steel for suspension components because it simply is not a suitable material for it.

@V iking: Your statement: "316 more for architectural use" is at the very least questionable. Without getting into detailed specifics, mild steel has a yield strength of 240-250MPa. Grade 316 Stainless Steel has a similar yield strength (circa 250MPa), so it would be my choice if I was replacing the trailing arms in question without any accompanying engineering analysis. Grade 316 L (low carbon type that is commonly used for the construction of boilers/pressure vessels that contain high temperature 'acidic contents') has an improved fatigue strength at a modest expense to its yield strength - so is also a good option - but more expensive than 316. Grade 304 Stainless Steel has a yield strength of circa 205MPa - so if used to create an exact dimensional copy of the mild steel version, the trailing arm would be "weaker" and less durable due to its reduced fatigue strength when compared to mild steel. However, if the appropriate 'engineering analysis' is conducted - then SS 304 could be adopted by using a modest increase in material thickness or a change to the trailing arm's shape or construction. Needless to say, an engineering analysis (i.e. load analysis and mathematical modelling, using Finite Element models) would be expensive to perform and would be overkill for 'this Lotus project'.

@@ALINUED stainless is brittle, mild steel is flexible

That’s proper tea! Thanks

…and all made possible by welding 😉❤️ thanks dude

Yeah I might well end up going back to standard, we’ll find some answers eventually

Wouldn't cost much to galvanise them.

😆

Probably no different to the originals 😆

Woah woah, easy there horse! 😅

🤣

Love that user pic! See you soon

Cheers Michael

10/10 🤣

The trick is finding someone with reliable definitive knowledge to have the conversation with 🤷🏻‍♂️

weld a couple of pieces together , then get a big hammer or a pry bar and spend a few hours trying to get them apart. That will tell you about '' hydrogen embrittlement'' !

Go to the engineering section of your local university and ask... internet experts are just that. Most engineers can't be shut up about their specialist topics 🙃

Good shout. So much learned already, especially about ‘forum knowledge’ and it’s pitfalls

Thanks Andrew 🙂

His shiny metal ass keeps showing up

Cheers, CCCN

But it’s not just about the car. It’s about the process. The gratification comes from taking the time to do it right and learn on the way.

I agree with Joshua...

I check myself every no an again when the situation gets on my nerves… I’m thankful to be able to keep working. Good luck with the search, it’ll work out eventually 🤞🏼

Thanks man, thanks for being here

I’m more worried about whether to paint the uprights black now in stead of silver, to compliment the SS arms, than the SS arms themselves, Mykl 🤣

@@soupclassicmotoring That is the true conundrum! 😆

🍻

Don’t worry, nothing is binned! It’s all just experimentation and learning. May we’ll go back to CS. Thanks a mill 🤘🏼
