amazing it's a high level skill

In my 51 years of machining background I had to make a tap only once. Very nice work and good and interesting video too.

Очень умно , больше бы таких людей на свете .

Hello my new friend I'm here to watch it's a very good video.

A good idea when you need to urgently cut a thread, but according to the correct sharpening of a thread-cutting tool, the tap must have a backed part, otherwise it is a bolt with grooves))

Nice work. That tap is the size of a broom stick!

For any future heat treating where you are unable to remove the outer surface afterwards, try using some high temperature paint meant for like 2000F, and paint the thing you are heat treating. This will protect the surface of the metal from becoming rough, and it will be harder as carbon will not seep out, called decarbonization. You could use a gas filled kiln, but that's expensive.

Simple, straight forward and real. I'll try some day.

THAT'S THE SKILL LEVEL!!! NOT EVERYONE WILL BE ABLE TO MAKE A TIRE IRON THEMSELVES

Sorry, but I would regard this as an emergency tap only, the sort you make and use when something needs to be got working and the correct tap is not available, and I have had to do this to enlarge a damaged1 1/4" BSP taper threaded hole to a sufficient extent to permit the 1 1/2" tap to start. As demonstrated, it works in thin metal, but if you have a deep hole to cut, it will take a large amount of force because there is no relief on the threads. I think I cut about 10 flutes and still had to use a lever about 2m long to turn the tap. Easier to take a high tensile bolt of the right size and use a grinding or cutting disc to make the flutes, if such is available. A real tap has its threads cut (or ground) at a number of settings off centre, to correspond with the number of flutes. Cutting the flutes in the right places then allows relief on the threads (like front clearance on a lathe tool).

बहुत सुंदर वीडियो

Very nice work. Well done. Thanks for sharing. Take care, EM.

que belleza, muchas felicidades al genio fabricando, no se nada de torno y ver este video, se me hace fantastico lo que hacen las herramientas y el ser humano. gracias por compartir

Хорошая работа.

This is so great and precisely done.I love this job

And, rotate the chuck counterclockwise, as you cut the flute deeper, to get more relief on one side, and more cutting angle on the other?

As a machinist i really enjoyed watching this video

Wow! Nice job on that tap.

One thing I couldn't tell, but did you slightly offset the endmill up/down so that it cut in relief? Or did you do that all post harden with the grinder? Either way, I'm going to steal your lathe milling technique. Lol. Nicely done.

Have made some reamers, but never a tap...a useful thing to be able to do. Nicely done! :)

Good result ! Congrats ! You could relieve the back of the thread a bit - it doesn't cut there and it'll make it easier to push through the metal.

Me encanta ese trabajo, soy psicólogo, pero la tornería y los trabajos en metales me fascinan, muchas gracias por compartir

Excellent job. Well done.

Trabalho super dez muito profissional top de mais

Excellent video, you show every step of the process so nicely that I believe anyone could make one of these in the home shop. Sub'd and liked, cheers!

Excelente trabajo ,quedó como de fábrica

Que trabajo más satisfactorio!

très bon travail avec précision fonctionne à merveille ...........!

Good Job🏆🏆🏆

Nice job, but it looked like he took the sharp edge off of two of the three flutes with the hand grinder. It looked like the grinder touched the OD of the tap. I am sure it would work for a while, though, depending on what you are tapping.

Great work sir, excellent salute.

You can literally do this with an old bolt and grinder , the bolt works good because it had a hex head for a socket . Never waste money on taps again . ^^^^^ This guy is making it ace but you really don't need to goto this extream unless you want to . ^^^^^^

Perfect! I love It.

This project is very good!

Nice job, you can make any size tap this way.

Good job! But I recommend using oil for threading!

Show, muito bom.

Actually, I think that it's a better practice to do the size reduction of the shank as the last phase, so that you are working with the maximum rigidity of the part during the cutting of the thread and flutes... Or, so Joe Pi has taught me...

Nice workmanship. 👍

Nice work,you would feel quite satisfied with that job I reckon

Top Job, Sir👌

از ویدیوی زیبایی که تهییه کردی و صدالبته هنر بی‌بدیلی که داری بسیار لذت بردیم هموطن عزیزم🙌🏻 امیدوارم قله‌های ارزوهات رو فاتح باشی🙏🏻

Thank you! 🙏

சிறப்பு தம்பி 👍 💐

Wow immaculate tool making work.

Bravo meseriașule asa o sa încerc și eu bravo la fel folosesc cuțite lipite dar trebuiea sa ne areti strungu pe care ai lucrat bravo

Very nice." I've always wondered how it can be made. 👍🌷

Dobra robota tak trzymaj

Awesome video, really enjoyed it!

Very very nice a job well done congratulations. ✌️🇨🇦

Excellent vid, thx! Which steel material (exact designation?) did you choise and why? Can you tell more about the hardening process? When it glows red just off into the oil? which oil?

Parabéns amigo muito bem feito viu👌👌💯👊👍🥰

Amazing Skill, Waiting nexs video

Bravo Turkey İzmir selâm 👍🌹

Excelente trabajo.

A EXCELLENT WORK.

Perfect job! I need to make an ACME tap 10 mm x 2.5 for my Harrison M 300 compound slide nut !

Great job.

Amazing beautiful job !!!!

Muy Bueno Quedo el Macho !!

請問一下，加熱後泡的油是什麽油？ 一般廢油？ 特殊油？

没有磨出切削刃的后角，阻力应该很大，切削刃寿命也不会长。

Nice clean work 👍🏻 Keep it up ❤️

very very cool. Straight to the point and well made.

This is the first time that I've ever seen anyone put relief on with a die grinder.

Very well done🙌

this would be a great idea for a metal shop.

Bastante bien eres un crac tio🤚👍🇦🇩🇦🇩👍🇪🇸

Отличное видео. А плашку можешь сделать?

Bellissimo lavoro!!

Excelente!

Thank's it's a good inspiration, to make an other tool. 👍

Very nice work, good luck to you my friend, I have subscribed to your channel before, our explanation is great, I wish you a good day and good work.

That was very good. WOW!

Would have like to see the burrs left in the thread form being addressed, rather than just a cut shot to the finished thread form.

Beautiful tool made by a wise man.

I started watching this and thought you where nuts , but then I started thinking, let’s say you don’t have a metal lathe and milling machine and your in a pinch. Then take a grade 10 bolt and chuck it in a vise and with a couple of mini grinders just cut the flutes in the bolt and be done with it. I don’t know the difference in hardness between a grade 10 bolt and a HSS tap. But maybe for a mechanic in a pinch that needs a real long shank tap to chase treads down deep in a casting might do the job. I’m going to try this on a grade 10 bolt. Also those Allen head bolts are real hard to and they might work also.

SUPER 👌

Good work! Wouldn't you normally polish (lap?) the treaded part for smoothness as well as for cal rather than the flutes?

Well done. now you convinced e to make all my own taps But here is a hint to make it cut easier Seeing you had to apply pressure to force the cut. If one is to grind or enter of the leading taper the leading edge as per taper grinding at an angle, so it will throw the cuttings down, instead of at 90 degrees, it will tap much easier Sorry i forget what they call that type of tap, which i prefer to use, Not sure if it is called a twist tap, but i hope you get the idea.

Wow. That might well be the finest threading tool geometry I've ever witnessed. Tell the truth. How many out takes were there 😉?

what kind of material did you use for machining the tap? = Qual material você usou para usina esse macho?

Nice work 👏

رائع ومُفصّل ومباشر وواضح ، شكرا لك

Muy bueno y se le agradese por enseñar esto.

After you hardened it you didnt draw the temper & when threading the block of steel no cutting fluid 🙂

Good job, congrats.

Que bacana, muito bom! Que material foi usado??

Muy bien echo maestro 👍,una pregunta que hacer es el que ocupo para fabricar el machuelo,deberia de hacer uno de de un dado tarraja,una humilde opinión para complementar la cuerda macho y la cuerda hembra.

What kind of steel you use for that tap??..greetings from PARAGUAY 🇵🇾🇵🇾🇵🇾

Wow , that's what I want to see diy TT.

Wonderful 😊 explained

Muito bom

Love watching the chips fly. OK, ya got my sub. Very first time I saw you.

I like this!

Perfect 👏👏👍👍😎

A very entertaining and interesting video to watch, in this case you have made the number 2 right? Because they come for games of 3, one of input, one intermediate and the one of output. I subscribe to your channel, keep it up, and I hope to see more videos like this. 😄😄😄

What type of steel are you starting with. Great job.

good job dont forget cut oil
