Guys who downvoted.... It's a thread RESTORER. Used to poilish up or correct imperfections on an existing internal or external thread. It is not intended to replace a Tap or Die which are used to create the thread, just to clean up an existing one! I've been an engineer twenty years now, and this is one of those useful tips that the older guys used to pass onto us as apprentices. Thumbs up from me!

Very cool and inexpensive hack to renew damaged threads. To those of you who are thinking of this as a tap, it is not. It is a tried and true way of repairing damaged threads. Great video.

A good machinist still knows all the tricks!

I'm restoring an old tractor, and in the process I learned the difference between taps and die's and a thread chaser. Damn, now I know how to make one.

Now...Those are the hands of a real Workin Man 😁

Little gems like this are so simple and yet... So smart and effective.

That is quite good, I have done it myself. I heated them up and dropped them in water which hardened them a bit and it made them a bit more efficient.

I am a machinist all my life. Now 73. I never saw this done before. Much appreciated.

Clever and cheap. No need for hardened steel just to chase out threads, however a little oil would probably help. Thanks for the vid and I hope you keep them coming.

You are a dying breed sir, love your creativity.

Thank you شكرًا

Thank you that was great. I know, I can use that from time to time. Thanks for sharing with us.

Kewl idea. Make your own tap and die. Put a torch to them and drop them in oil to harden them some, so they won't use up, real fast. Greatbidea! Thanks so much for taking the time to make the vid!!!

Muchas Gracias, muy buen trabajo!!! Saludos desde Argentina!!!

Now I learned a new repair today. Thank you

Exellent work thanks for the video

Good idea, simple production

Brilliant idea who would ever think of something like that I'm amazed 😮

Good on you old boy! Learned something new and costs next to nothing. Please share more!

like it very good idea thanks for posting 👍

That is really cool , Thank You

Beautifull work Congratulations!

Super helpful!

Sir, your an amazing whistle builder.

Thanks for sharing the video. Keep up the good work.

Great idea! I have a "master" thread restore kit and it's missing a couple sizes, now I can make ones to add to it!!

I'm an instrumentmaker who makes a lot of his own tools, including taps and dies. Great idea about cutting the channels with a drill bit. Keep up the good work- and thanks.

FINALMENTE VI ALGUMA COISA UTIL HOJE..TUDO DE BOM!

Took a sec to figure it out but it's one of them late night fix ideas. That could decide weather you have to work Saturday night.

Amazing and simple.

Really great idea, thanks for sharing! Is it an option to harden the "tools" afterwards? Heating and oilbath?

sir this videpo is freaking awesome!!!! thanks so much for teaching all of us this skill

Practical and useful. Thanks.

Love amazing use of simple tools that do a sweet job add a voice to you videos be nice to hear your inspirations and method and why said method love to hear people talk about why this way and not that being a production engineer my self

incredibly smart! Thanks for the tip!

Good idea but I just put some wide hacksaw cuts into the end of the bolt. Then oil it and and use that to clean out threads in nuts.

Really smart idea that mate, I'm going to try this one out for myself and also do a heat treatment on it as suggested here in the comments. Thanks folks hopefully it'll work out!

great old school trick - thanks for sharing! could have saved me a few times before of buying a special thread cutter

Great video. I have noticed a lot of comments about it being too soft and not hardened. HE plainly stated it's to restore the thread. A hardened male or female tap would cut distorted or bent threads off, but a softer assembly such as the one he made would reorient the threads into their intended pitch. The addendum of the thread is what would need reoriented. As for the heat not all bolts harden in tensile to a simple heat and quench. Granted, the bolts in this video are not stainless hence the rust they may or may not harden in that fashion since they may be of the wrong carbon content. What this man has done is demonstrate on old machinist technique, and he should be applauded for trying to keep these techniques alive. There are very few people that know how to do this. Cheers.

I think it is very clever and could be useful.

Very good. That cylinder head bolt would harden and temper perfectly. Cheers Stuart 🇦🇺

فكرة رائعة ... شكرا لك

Boa criatividade e muito útil, Parabéns!!!!

Excellent merci pour les astuce.

wow... incredible...very good idea, good video

Very Old idea, I'm glad to see someone teaching old school machining. we did this 50 yrs ago in Hickory Ridge Machine Shop Blacksburg, Va. Trubble W

Nice. :) Handy little trick to add to the repertoire.

nice idea simple like all good ones

Muito bom...

Good for dents, any other time try a new bolt and nut. A steel brush do a good job too if it's a rust/grit remover you want.

Please don't bait people with the word "invention" in the description. This is a good idea for those that don't want to buy a die nut or tap, but to call it an invention is stretching it a bit.

First time I have come across this idea. Well Done! Don't know if I will get around to making one but I use a lot of 1/2"-13 nuts and bolts that always have a tight spot or too. I either just go with it because sometime the time to clamp and properly turn a die might seem like a chore. I do some off site assembly and this would be quick way to chase a bad nut or screw if extra weren't around. If it is effective. That is why I am curious to drill three holes and find out!

Hello,thank’s from 🇧🇷 !! 👍🏻

Muito bom, é um limpador de roscas, parabéns

genius !!!!!!!!!!!!

nice work, I like the antique end wrench

Muito bom amigo ....Só fazer a tempera do aço para aumentar a dureza!

Very informative and useful trick... but I think his dad teaching him the trick was the best part of the video.

sehr gut! im Bedarfsfall tuts oft aber auch schon eine Eisensäge und ne 3 oder 4kant Feile einfach bissel schräg ins Gewinde sägen etwa 3-4mm tief je nach Schraubendurchmesser dann mit der 3-4Kant Feile kräftig ausfeilen und dann kann man so die Schraube oder Mutter zum nachschneiden des Gewindes nutzen und das auch im Notfall beim Wochenend/Horror/Panik schrauben :-)

Onya!!!!, Mate brilliant idea. Thanks for Your vid, Good job and once again, Thanks also enjoyed background music

Awesome idea 😀👌👌👌👌👌

You should heat all of the pieces you made to cherry red and then dump them in oil to harden them... it might improve your product..

Круто! А почему не использовались привычные метчик и плашка? В виду не имения под рукой данных инструментов?

Very clever idea thank you for sharing 👍

Genial...!!! Thanks.

Sir, amazing video, you have reduced my bills on fasteners by nearly 75%.

Good idear ha sometimes I just cut a small track in the bolt the lengt of it works good to FairPlay

Wow! Bolt's thinking was really creative and cool.

Very good job!... Congratulations, teacher ...

Enjoyed the video keep up the good work

parabens o sr e um mestre ja sou inscrito.

Would it help it if you fire heat it then quench it in oil

You could add a little cutting oil when restoring the threads, everything is better with a little lube

Great idea if you're ever in a jam and don't have the right size thread. 2 THUMBS UP

Отличная идея!

Great tip! Thank you

Definitivamente I like it, thumbs up.

Great idea and simple at the same time which is all it takes

Author Self-perfection Handsome man of his craft. That's the idea. I have a lot of work at work, now I definitely try to make a left tap on M 16 x 2

these home made tap and dies are ideal for us woodworkers who may need to add a thread into wood. i make them all the time when i need a specific bolt hole. and to the trolls out there threading a piece of wood and inserting a bolt is extremely solid.

Thank you for the video

Brilliant!

UNA EXCELENTE IDEA 👍 saludos .

very informative for people with zero shop experience. Even the harbor freight tap and die would be better. thanks anyway

As soon as my wife is finished with the kitchen drill press and vice I'll try this home made invention!

Great idea, saves me buy a tap and die set. I suppose you could use the same principle to create the threads?

Amigao Deus abençoe vc é sua família. Amiqo. Ficou muito boa asua. Ferramenta abraço. É fica com Deus

ВАУ ЭТО ПРОСТО ГЕНИАЛЬНО!

Kinda cool custom chaser build, now I know how it I ever need a thread chaser that I can't find in stores

Certainly the metal will be soft; but remember you aren't cutting a thread, you are merely re-establishing what is probably a slightly damaged or rusted thread.

Damn good machinists tip

I was like what is he making then like sweet idea nice job.👍☺

So Cool! You just taught me how to make my own tap and dies. I know those who invented this probably think nothing much, but I now see how I can make my own with nuts and bolts. I learned something important today... Thank You So Much !!

Thank you... for this idea... :)

Thanks for sharing this great idea!

super le tareau de filetage 👍

Great idea!!

A mi me tocaba repasar las roscas cuando ayudaba a mi papá. Me hizo acordar a el y sus inventos

olá amigo muito bom sua envesao

Thank you very much. My inspiration is added
