steel hardening technique which is not taught in school. Make a sharp spiral TAP
Warning: This screw tap is only used to clean and repair dirty and deformed nuts, not intended for very hard dead iron.
I made this diy left screw hand tap to make nuts on spare parts for tie rods on trucks, which often experience damage to the nuts, so I made a DIY hand tap to speed up repairs and for the hand tap I did hardening to make it stronger and more durable.And in this technique I use salt water as a cooling medium, hardening the steel.

![6 Practical Drill bit Sharpening Hacks !!! [Subtitle]](/img/n.gif)
When I went to Lane Technical High School in Chicago in the 1970s, two years of shop classes were mandatory. I took wood shop, electrical shop, foundry, machine shop, and forge. I and hundreds, perhaps thousands, of other boys were able to use and make metal tools and heat treat them before we were 17.
A country flourish when it's citizens armed with knowledge. Well educated workers are the back bone of industries. I watch this like magic but I am in a totally different field. But I am pretty sure that people in this field in my country aren't in the calibre to understand this.
Cool. I firmly believe that at min. everyone should have to take 4 semesters of classes in 'the trades'.
Сэр я учился в СССР 1985-88 и тоже сбивал руки на производственных практиках. Но глядя на профанацию показанную в данном ролике понимаю всю степень деградации производственного процесса. Такие ролики не для наших нервов.
Yeah, we learnt this in High School back in the 70s. I frequent a place that has a reasonably outfitted metal workshop - out of a contingent of 100 people, there are only 3 of us (and only one of those under 30) that use it. In the 70s it would have been full to the brim with young people vying for time on the machines. It's a real shame.
Clickbait. quenching, annealing, post heat treat is basic engineering material science taught in school.
Да... такой технике закалки не только в школе не учат (в школе вообще закалке не учат). Но даже в училищах такое не покажут: бросил деталь в воду - и все (правда, перед этим насыпал волшебной соли). Сколько я видел термистов, ни один так не делал. Опустив деталь в воду, они ее там болтают, чтобы остывала, а не паром, не проводящем тепло покрывалась. Спасибо хоть погрузил в воду вертикально, а то некоторые спецы в воду боком опускают, а потом удивляются, вроде точили прямую, а деталька изогнулась.
А еще, каждая сталь калится при определенной температуре, определить температуру по цвету - нужен большой опыт Судя по манере бросания детали в воду у мастера этот опыт вряд ли присутствует в наличии.
Сталь КН конечно можно калить при температуре КП но, результат непредсказуем.
(для тех, кто в танке: КН - какую нашел, КП - какая получится).
Thanks 🙏🙏👍
Солёная вода, как охлаждающая жидкость при закалке, иногда применяется. У неё теплоотводящие свойства несколько выше чем у простой воды, соответственно скорость охлаждения выше, степень закалки соответственно тоже. Для каких марок сталей такое применимо, к сожалению не знаю. я слесарь а не термист.😉
@@panstakanski6116 А не надо быть термистом, чтобы оперировать простой логикой. Он насыпал соль в воду (как вы говорите, для лучшего охлаждения). Но не стал перемешивать воду деталью (при этом она значительно хуже охлаждалась). Я так и сказал: насыпал волшебной соли в надежде, что она за него работать будет.
А вообще закалка в соленой воде - вещь специфическая. И применяется в основном при закалке труб из низколегированных сталей для упрочнения трубы, работающей на разрыв. Что еще раз подтверждает, что для этого _специалиста_ соль - это волшебный порошок что-то там (но неизвестно что) улучшающий. Магия. Ну нафига метчику прочность на разрыв? Ему поверхность нужна твердая.
@@Walker7745просто солёная вода препятствует образованию паровой ванны. В термичках используют 1 кг соли на 10 литров воды.
@@Walker7745 могу только дополнить, как слесарь, что это изделие не метчик. По сути это закалённый болт с продольными прорезями. Режущие зубцы у нормального метчика должны иметь затыловку конусность. Этим наверняка и объясняются несуразности на видео. Резьба там скорее всего не получилась. Таким только ржавые гайки прогонять.
My Dad, who became a machinist, believed that a tool and die maker was the ultimate machinist's aspiration.
Yes, being a toolmaker, die maker, or mold maker was a way to show to yourself and others, that “you had it”. The work tended to be more varied in scope, and challenging on nearly each day. But, the title, or card from a program, was not what made the man. Producing the products needed, and not being afraid to share what you had learned, either on your own, or with the help of others that came before you, or even the ones coming after you, that had their heads screwed on straight. The sin, is in not wanting to listen to the thoughts of others, and not to give credit to the kid, when “the boss”, complimented you for the results.
@@robertqueberg4612нужно хорошо знать свойства, технические характеристики всех металлов 🤔

Its all quite simple, it is amount of carbon and in some alloys other variables that determine the properties. But iron and carbon make steel and amount of carbon equals how hard it will be. Mild steel (low carbon content) will remain mild steel no matter what you do - heat it to melting point and quench in royal jelly, it will still be useless as a cutting tool. You need the right material and correct treatment. Just a fast quench will leave most harder steels brittle...You need to do the next process... To ensure some toughness.
🙏👍👍
Mild steel can be made harder by using a surfectant, probably just a 'skin' though? (tests were not particularly 'scientific' just a hardness tester)
As you say, water, even with salt does nothing at all to mild steel
@@1crazypj You can surface harden, carbonising being most used, infusing carbon into the surface.
@@martinda7446 Yep, I've case hardened stuff in the past, used Kasenit but there are a few other compounds manufactured in different countries.
Plus, the ancient 'burned' leather method of case hardening

I liked metal work lessons in school.Our teacher did teach us that a high concentration of salt water is ideal to be used for quenching steal for hardening as the the salt prevents tiny air bubbles if were present would leave tiny weak spots on the metal.

this vid definitely has tons of fake views, likes, and comments. this is a normal heat treatment with literal snake oil thrown in
With no mention of the carbon content being necessary for hardening. Also love the grinding on unprotected ways
Brilliant 👏 God bless you hands and mind.
Attrezzatura..........e sopratutto PALLE ottagonali !!! Complimenti !
Clickbait thumbnail. He never used rebar
The circular form you used to cut the helical flutes gives you a negative rake. I believe if you cut below center you will reduce the negative angle.
If you mill the flutes with a ball-end cutter below center, you can create a positive rake.
Thank you very much for the advice 🙏👍
The best thing about a lathe, you can make more tools that work with the lathe. What ever you can think of, is doable.
This is quite a versatile lathe, being able to cut the helical channels!
Thanks
Yeah, I wish more people had them and knew how to use them. Would give almost anything to be able to have one myself.
@@LuggageStardate Yeah, I've actually seen shops do that for the most part. If a person has time, but not a lot of money, he could make nearly any tool he needs to make nearly any tool he needs to make any tool he needs. I think there are some occasions though when it's cheaper to just buy tools instead of making them. Some tools also require a great amount of skill and/or a great amount of knowledge of math and geometry.
@@deucedeuce1572 That's so true. There are always trade-offs. I like making tools, jigs, etc. I collect a lot of 'scrap'/'junk' for later use, and even then if I need parts (bearings, rods, connectors, etc.), the price can surpass buying a mass-produced tool.
I wish we could've seen the thread making in super slow mo.... That was tough to wrap my brain around. 👍🏼😁🤷🏼
Just watch at slower speed??
Smh
You can also make "super-quench" by making brine and adding dish soap, though i cant remember how much soap to add. That makes it dissipate heat a bit faster than brine, i dont know how much though. If you know that your steel can be water hardened, you can try brine. If brine works, you can try super-quench, me thinks. But cracking or warping become an increasing risk...or guarantee...havent started yet to find out. But preheating your quench liquid can prevent thermal shock
Thanks 🙏🙏

Amazing skills you have sir! The lathe is the only machine that the make duplicates of itself, with the right!❤ person!
Thanks 🙏👍👍
At 6:35 you can cleanly see he stopped short and didn't cut threads all the way through. At the end of the video when he cuts the nut in half to show you the threads is not a nut at all but a cut off piece of round stocks with internal threads. More jump cuts than a Chinese tool demo o_O
Первый раз слышу что бы в школе закалку проходили😂😂
🙏👍
Impressive skills being used with basic equipment and providing a good job. Also some cleaver operations which could save time, such as the flats being made while still in the lathe.
Thanks 🙏👍
I was wondering about rake & a relief angle, but it certainly worked to thread that nut..nice job- creative using what is on hand.
🙏🙏👍👍
Wow, that is one beautiful lathe. I've never seen a drill attachment for the compound before. Nor have I seen a lathe that could cut a spiral (thread with such a high pitch.) I am envious!
Thanks 🙏👍👍👍
Ухочес- где стружка от метчика самодельного?
👍
Sir...that was amazing!!! Thank you❤🙏
🙏👍👍👍
Присмотритесь, все разные метчики в видео. Присутствие обмана.
👍👍
What struck me here, was chucking in the water ,and just leaving it at that angle, you will create a likely fracture line where the steel enters the water. Should be moved gently up and down... and then tempered afterwards TOO! Don't expect it to last very long fella...

I love Argentina. I spent some time working in Biaha Blanca. Great people.
I heared about red heating tools, submerged in a melt of salt, to avoid the oxidation on the surface.
On the other hand I just don't know what quenching into an solution of water and sodium chloride would possibly do !?
By the way - Is there no tempering needed after quenching ?
مشاء الله مبدع والله يا معلم 👍👍👍

Hangi okulda öğretmemişler anlayamadım.Üstelik bu yaptığınız sıcaklık, soğutma hızı( soğutma ortamı) ve malzeme cinsinin fonksiyonlarını gözönüne almayan bir yöntem. Ölçme vs. yok. O yüzden bu şekliyle okullarda anlatılmaz. Her malzeme ve istenilen sertlik değeri için malzemenin ısıtıldığı sıcaklık, soğutma hızı (yani soğutulduğu ortamın iletkenlik derecesi hava,yağ, tuz vs) ve soğutma süresi bir faktördür.
🙏👍👍👍👍
Was a pleasure to watch your skills. Thank You for sharing.
Thanks 👍
Yeah, saltwater hardening is a thing. Also, please sharpen your cutters more often, the uneven scratches left behind in some of those cuts hurt to look at.
🙏👍👍
It is, after all, hard water……
I love honing my sharpening skills :)
I've got so many drill bits from people who don't know or care to sharpen them. Also, knives, scissors, etc., I'll often take a bunch and sit down and sharpen them either for my own use, give them as gifts, or donate them. I hate watching someone I may be working with struggle with a dull tool.
To my knowledge, only carbon steel and high speed steel is used to make drills & Taps.

Not sure what school you went to, but it certainly is taught in school here, or at least was when I was there, but water quench is a bit harsh and can cause the metal to be brittle, we prefer oil quench
I was taught that in 11th grade over 60 years ago. Salty water is better than pure water, but can still cause brittleness as it cools off too quickly. Oil is always better, even old used dirty oil.
@@gadgetroyster I once read the two processes can be used together to achieve better results, but I don't remember the details. Heat and water first, then heat and oil, or viceversa
It depends on the steel, and you definitely need to know the alloy. Oil, water and salt water all have different cooling rates. Salt water is a faster quench than plain water, and can crack or shatter some steels where water would produce a good result.
The key thing I learned in school is that it *can* be done, along with "look up the details when you need to do it".
@@gadgetroyster It's actually an 'old wives tale'.
Any surfectant works far better (dish soap)
I remember seeing the tests done with salt water compared to soapy water, the soapy water allowed even mild steel to become significantly harder (although still only around 40 ~ 45 Rockwell C)
The quench isn't what makes a metal too brittle or not brittle enough, it's the tempering after quenching that controls how brittle it is. Apparently your school missed basic metallurgy, which isn't surprising since most don't teach it at all.
Have you tried making tempering with aloe vera?

Claims special knowledge about something schools fail to teach - comes to work in flip flops.... that sounds like a real winner!
🙏👍
It's not special knowledge, it's just that brine quenching isn't often taught because of the fact that it can be harsh on some metals and cause them to crack due to the faster cooling times compared to water quenching or oil quenching.
