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.

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

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

Boa noite a todos, não querendo desmerecer o trabalho, trabalhei 15 anos numa fábrica japonesa de machos frescas e Cosinetes,,um macho não é simplesmente só isso.!!!!!

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

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).

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

बहुत सुंदर वीडियो

As a machinist i really enjoyed watching this video

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 . ^^^^^^

Good Job🏆🏆🏆

Хорошая работа.

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?

Great work sir, excellent salute.

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

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

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

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

Wow! Nice job on that tap.

Bravo Turkey İzmir selâm 👍🌹

Good job! But I recommend using oil for threading!

Excellent job. Well done.

Wow immaculate tool making work.

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

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

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.

in reply to some of the comments Believe me a guy like this does'nt make mistakes like not leaving a cutting rake on the business side of the tap

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

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

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

Отличное видео. А плашку можешь сделать?

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

Excelente trabajo ,quedó como de fábrica

Trabalho super dez muito profissional top de mais

Que trabajo más satisfactorio!

Amazing Skill, Waiting nexs video

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.

This project is very good!

Amazing beautiful job !!!!

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.

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...

சிறப்பு தம்பி 👍 💐

That was very good. WOW!

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

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.

this would be a great idea for a metal shop.

رائع ومُفصّل ومباشر وواضح ، شكرا لك

Awesome video, really enjoyed it!

Thank you! 🙏

good job dont forget cut oil

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!

Great job.

Top Job, Sir👌

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。

Perfect! I love It.

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

Nice workmanship. 👍

請問一下，加熱後泡的油是什麽油？ 一般廢油？ 特殊油？

Muy Bueno Quedo el Macho !!

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.

Wonderful 😊 explained

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

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

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

Good job good luck always

Nice Hobby, expensive part.

Profissional que quase não depende da indústria para bons resultados... Professional who almost does not depend on the industry for good results.

Show, muito bom.

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

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

Very bealtful

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

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

Thanks, is the ball mill on center?

ese machuelo se me hace una obra de arte

Now do a gunn tap grind at the tips and make it perfect! Spiral chips but not as convenient on a blind hole.

Excelente trabajo.

A EXCELLENT WORK.

well done . to make something even better, go ahead and make trapezoidal thread tap.

liked your video, i've made taps that way outta O-1, what kind of little spindle do put on that tool post? One thing, you did not seem to need a relief angle on the front end? easy enough to do on belt sander free hand, thank you!

Nice clean work 👍🏻 Keep it up ❤️

Bellissimo lavoro!!

Bagus , good 👍👍👍👍👍

SUPER 👌

Good job, congrats.

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

How did you put the clearance on the chamfer lead of the tap ? It won't cut unless you do.

I like this!

And cut the thread on the back side, away from the chuck?

Majestic

Excelente!

Nice 👍

Those taps dont work for long. You can harden as much as you like. Real taps are mostly HSS. I made a few myself back in the day, they work fine up to a point, then you have to throw them out. But ill give you a high 5 for good work.
