Awsome thanks for sharing I have been a machinist for 30 years and never seen this simple technique, just goes to show you are never too old to learn.

I'm a Tool & Die Maker and while I did know about this. I never had a reason to do it. Still fun to watch.. thanks!

Thanks, I couldn't understand a word, but the video explained perfectly!

That spark plug was genius hack and it make sense as ceramic friction drills are a thing. Its more durable, abrasive resistant and isolator so it dont suck up the heat from the part.

Impressive work and important information to learn..thank you!

Отличный и надёжный способ для соединения различных деталей из разных сплавов, постоянно его использую в процессе работы на производстве. Правда почему то некоторые марки сталей не хотят сваривается подобным образом.

Thanks.. love the spark plug use..

Absolutely beautiful. Thankyou for the insight to your techniques and knowledge.❤❤❤❤

Wonderful demonstration, thank you for making this video.

Maravilloso!!!!

Very cool!

Wow, this is amazing! This opened up a whole new range of capabilities for my lathe work! What an effective technique for necking-down tubes! The welding of dissimilar metals is extremely interesting as well! (As others have said, what would be ideal would be something like a chuck mounted on a live center, with a pin to keep it from rotating until you were ready to stop the process.)

Интересно.Разные металлы я так еще не сваривал.Респект и уважуха)

most interesting thing i´ve seen on youtube for a long time

Que experiência incrível! 👍🏼👏🏼👏🏼

very cool tricks

This is amazing. 👌

Wow beatiful vary good 👍🏻💯💯

I’ve seen several lathe videos. But this was the best.

Good stuff! Will copy!

Thanx. I learned a bit today.

I'm not certain if you are a bloody genius or if you are stark raving mad! Maybe a bit of both! To say the least, that was impressive!

Деякі прийоми вже роками використовував ,а от кулька з трубкою👍👍Дякую

Very nice work

Maravilloso, alucinante, bárbaro!!! Me volví a enamorar ❤❤❤

Well that will certainly lower tooling costs. Nice hack.

Beautiful.

Adorei 👋👋👋👋👋👋são Paulo 🇧🇷

Really impressed.Never come across this before.I want to have a go but not sure my Myford Super 7 will run that fast. So good to know about though.

Molto biene!

Çok güzel bilgiler ve etkileyici anlatım için teşekkür ederim

Molto interessante Ciaoo

I was shocked to see but then I understand Very good

3:51 THX sound effect 😂😂

🎉🎉🎉

Molto biene!!!!

Bravo

Wow. Outstanding!!..........Kudos...........Z

Fantastic content

mindblowing

wow.

Отличное видео, спасибо

Amazing

didn't know you could friction weld dissimilar metals. that's pretty cool

Imbottitura per attrito 👍👍 fantastico... ovviamente con inserto d'acciaio per utensile comunque veramente certosino😉😉💪💪

عمل ممتاز وتقنيه راقية شكرآ جزيلآ

The bend test at each welded joint would be a good strength test for the mixed alloys.

calidad de demostracion saludos amigo

👍👍👍👍

Obrigado😊

good job, but that's not the right way to friction weld in order for the weld to be actually strong the machine has to stop turning immediately. your welds will not hold much

This was very interesting, I have zero experience with machining, but I see no one concerned about the integrity of the spark plug failing. Like the sideloading on an item that is not intended for any sideloading at all is kinda scary no? I guess you get a feel for how strong the ceramic is. Safety squints are hopefully on regardless of what your lathing. Very cool techniques.

Spark plug insulators are almost pure aluminum oxide! Very high temperature resistance.

Try using Stellite, which is highly resistant to high heat degradation due to its ceramic component. Plus it's tolerant to intense high temperature, to shock, and extremely ridged. I have used stellite cutter bars for lathe turning work. Mostly used for profile shape cutting tool for lathe.

How would its integrity perform over a long period as these dissimilar metals usually create an electrolysis effect (rusting them apart.) I have seen this process done with explosives, but have always wondered how the long term effect would be. Would they simply rust apart. Please do this test and get beck to us. Thank you, I love your channel.

Very nice

Just in case... please don't try to do this on a benchtop lathe or any lathe that doesn''t have the torque and horsepower required to do any of this. I dont know how much horsepower it would take at those RPMs but its gotta be plenty.

Have you tried this with a carbide blank as the tool?

Heating galvanized pipe might release toxic gas?

😮👍

Thanks for sharing! The most interesting part to me was the friction welding of the different materials. Aren't these materials not combinable with conventional welding??!

Brutal machine workout but beautiful to behold; both the process and the end products. One day though, one of those spark plugs is going to let go and he'll end up with a ceramic third eye.

ciekawe! brawo!

....... а вот сварка металлов на моллекулярном уровне -- это интересно !

In the first example with the thin tubing, how far did you advance the crossfeed saddle for each pass?

Maybe if you put more chamfer on the edge of the spark plug it wouldn't remove as much material ? I don't know, just wondering.

Be careful with the galvanized tube. When heating Zn that much, you can create vapours that are harmful.

Nice video, but be careful about touching the spinning work, as it could be a fatal mistake. Recommend to look up industrial lathe accidents.

Con bujías e imanes puedes lograr hacer lámparas que enciendes y apagan... interesante

Que top

I'd like to see the gun those bullet shells fit? Wahoo, gonna kick like a mule!😂

👍

How much material is removed and what is the Wall's final thickness, is the pressure rating lower at the narrowed part?

Na ja! + Material Stück ist gehärtet 😎50% Effekt i v i t ä t

Que crack!

ooooh so THIS is what ancient civilization parts are used for!

Такой обработкой, я занимался в долеком 1985 году. В чем новшествт?

You could try hot work steel (i dont know the real english name) its made to be used at glowing temp.

It seems English videos have been depleted of informative things, time to check different languages. Never seen a lathe spin so fast before. Was counting the fingers to check if any accidents happened.

could you friction weld with this technique? spark plug?

A lot of people do not know of this process because very few hobbyists laths have the raw power needed to do that.

😍😍fighissimo! Stavo pensando che forse si potrebbe migliorare se la contropunta inizialmente ferma, negli ultimi secondi della saldatura , potesse essere liberata dal blocco e potesse girare ad unisono con il pezzo montato sul mandrino! Tipo una contropunta su cuscinetti, dove possa essere bloccata e sbloccata! Questo , almeno a sensazione, mi da l'impressione che i tue pezzi in fusione , rimangono fusi , invece di subire un raffreddamento, dove una parte continua a girare e l' altra rimane ferma! E' solo una mia sciocca sensazione?

Фантастико. А если свечу заточить как резец?

Interessante, non so se faccia bene al tornio ma molto interessante 😉👍

I thought you always had to come to a sudden stop when friction welding ??

Интересный патрон таких не видел

Gracia! (Erevan)

Nice ❤❤❤❤🤩🤩🤩🤩🤩🤩🤩🤩👍👍👍👍👍🚿🚿🚿🚿

Даст из фантастиш 🎉

ممتاز

How are the spindle bearings doing

First Thing, maybe a tungsten carbide milling shank would be better.

I guess that you might want to heat treat a steel tube that is formed in this way..

Очень производительно, ноль стружки, еще и закалку можно сделать сразу.

Sensacional

А не слишком ли плавно останавливается шпиндель? Хотя, если перегреть, наверное пофиг.

una candela automobilistica taglia il materiale, il che è indesiderabile perché crea punti deboli nella parte. Se il metallo è sufficientemente sottile, esiste il rischio di tagliare parte del pezzo

Привет от Доктора Дью.

Метод интересный. Но работать с изолятором свечи только под вытяжкой и в маске. Пыль крайне токсична для органов дыхания.

Я так понял чувак использует токарку чтобы делать дилдаки😅
