Not aluminium

I used to work in an iron foundry this blows my mind. yet every one still has their fingers and toes from what ive seen.

No its just like the old days 👍

ikr? Guys will be guys though. Better to lose some toes than appear fearful or incompetent.

@@sgtstadanko880 the one that have accidents probably don't work in the industry any more.

indeed, far too hard for a very mediocre result (at best)

They make them and none are harmonically balanced to go on balanced pistons. Yeah I don’t think the engine will last it’s life time.

@notfiveo SWARF!

ol, you have no clue of what you are talking about obviously, this is not top notch by any standard.

Obviously, you have no understanding of machining tolerances. I am a retired ASE certified master engine machinist. The tolerances I was required to use were measured in ten thousandths( one tenth of one third of a human hair), not using a ruler and a set of dividers.

You mean these rings in the video is better?

@@charbelmaroun9914 I did an apprenticeship with a company called specialloid pistons which went into liquidation it was rumoured to turn out about a million pistons a year that's excluding piston rings and gudgeon pins they also manufactured aero engine pistons they were a supplier to Perkins diesel engines and can still be found today on the internet. They also manufactured for early diesel locomotives the delta engines and of course marine engine pistons which were like dustbins.

sunak and co would have every machinist in the uk working like this if they could abolish the trade unions since thatchers treachourous reign wages have went up about £10 in 40 years unfortunately most of the old knowledgeable gits are retiring and no one to replace them , what a total disregard for skilled men shame on you britain 😢

@@eweunkettles8207 What a load of twaddle! British machinists today work in safe clean conditions. They have the best world class equipment, best on the job training and are amongst the highest paid in Europe. They drive to work in their own cars, live in their own modern houses and have four weeks of paid holiday a year. They travel abroad with their families and overall enjoy an excellent standard of living. Take your picket line rhetoric away to some place it might be believed. There's no way can British manufacturing be compared to the third world amateurish and dangerous methods seen in Pakistan KZfaq videos.

Very good 👏👏👏🇧🇷

Cast iron is a great piston ring material for automotive too, very low friction compared to other alloys thanks to graphite stuck in its crystalline structure. It's only recently that cast iron was replaced by steel since modern engines are getting smaller and smaller but make more and more power per cc to beat regulations, and steel can resist abuse substantially more, especially when running it thin, again, for "fuel saving" purposes.

There are many grades of cast iron. A company once went through over 100 variations when designing a sleeve valve aircraft engine.

Even seems like the air compressor piston was also home casted, at least when you look at the last 3 rings the put in, when you get to see the inside of the piston But 3rd world country as we call them, seem to be good at repairing almost everything, if something break, make a new one. should that break, make one more

@@david929190 We have a company in Norway "Tizir" have over 120 different mostly iron/steel alloys to pick from, if you dont make a custom order that's not on the list, they make it for you fabric's over the whole world come to buy it, due to it's good quality.. Even the Zink they make here is amazing and that's Boliden

“Recently”? Try the 1960s. Steel piston rings have been used in aircraft piston engines since before WW2.

It would have to be for a very specific purpose I’d think, because it wouldn’t be able to hold work in place under normal turning work.

I like it so much that I bought the company.

What are you using it for? Cracking walnuts?🤣🤣

@@caddyrack no, just general use - 300gram, by Gedore - German brand, I think. It works especially well for small chisels and center punching.

lol, for an beaten air compressor maybe, but this is not combustion engine piston ring, it is dubiously made, from scrap metal.

well, you must not be well informed the, because these rings are obviously not for any combustion engine, they are only suitable for very low quality air or gas comrpessors, and even there they certainly have a very limited service life. Everything is wrong with this operation,, everything, from the material, to the operations to the finishing. You can see how the rings are not even centered on the lathe when they do the "surface finish". it is a joke.

@@lo2740 Precisely. The rings are machined in whichever fashion they fit in the lathe, one side they will be having thinner walls, other side thicker. This is pathetic to watch. Complete third world country recycling sweat shop.
