AMAZING HOME MADE INVENTIONS YOU NEED TO SEE 2018 

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!

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.

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

A good machinist still knows all the tricks!

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.

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

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

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.

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.

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.

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

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

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

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.

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

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!!

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

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.

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

That is really cool , Thank You

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

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!!!

very...Verry good ! bạn quá giỏi...Xứng đáng làm thầy dạy cho tôi.ước gì tôi có được 1 người thầy giống như bạn !

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

Чтобы почистить гайку достаточно сделать болгаркой 2 пропила вдоль болта, а чтоб почистить болт достаточно поработать щёткой.

Thank you very much. My inspiration is added

Good idea, simple production

Exellent work thanks for the video

Beautifull work Congratulations!

Boa criatividade e muito útil, Parabéns!!!!

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

It's a rubbish idea if we're talking metric or another readily available type of thread. It's a fantastic idea if we're talking more exotic threads; so yep: thumbs up!

Super helpful!

Now I learned a new repair today. Thank you

nice work, I like the antique end wrench

Awesome idea 😀👌👌👌👌👌

Very good, a bright idea.....

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.

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.

like it very good idea thanks for posting 👍

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

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.

Sir, your an amazing whistle builder.

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

Thank you شكرًا

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

You made a thread chaser. They are sold everywhere

ВАУ ЭТО ПРОСТО ГЕНИАЛЬНО!

Muito bom...

Practical and useful. Thanks.

Excellent merci pour les astuce.

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

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

Very good limey!

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

Definitivamente I like it, thumbs up.

I saved myself a lot of time and went and bought a tap and die set with chasers at the hardware store. Easy peasy

Amazing and simple.

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

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!

Hello,thank’s from 🇧🇷 !! 👍🏻

nice idea simple like all good ones

It’s called a tap and die set, and is typically made from hardened tool steel which is much, much tougher material than the vast majority of threaded fasteners.

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

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

incredibly smart! Thanks for the tip!

Not a bad idea. Now you need to harden them, carburize with sugar perhaps. If I don't have the proper tap to clean a bolt hole I just cut the "flutes" with a small zip cut.

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

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

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!

When you drill into the nuts and bolt, you should have sprinkled a little water to protect the drill tip from overheating. When you run the homemade "threader bolt" through the bad nut you shlould spray a little oil to avoid damaging the good threads; similarly with the threader nuts on a bad bolt. Good job.

Not to downgrade this video, because its a great example of making do with what you have, but in my last job before I retired, I would just walk over to the tool crib and get a thread chaser or die. LOL

Great tip! Thank you

You can manufacture a thread restorer in 30 seconds, just by using a grade 8, low-alloy steel, high-tensile bolt, and a 100mm angle grinder, with a thin disc fitted! I've been doing this for over 50 years! In addition, by heating the end of the bolt when cutting slots with the angle grinder, and then letting it air-cool, it hardens the grade 8 bolt appreciably.

Muito bom, é um limpador de roscas, parabéns

Просто КЛАСС , (раньше пилил болт и гайку на 4 части).

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

فكرة رائعة ... شكرا لك

Very,very good my friend!!

Amazing idea👌

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

Very good except when the thread is damaged on a nut or bolt of a higher hardness rating. Then it will re-tap your tool with its damaged thread profile - hence manufactured a tap and die set is high carbon steel

Enjoyed the video keep up the good work

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

Great idea!!

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.

чувак изобрёл мечик и плашку..гениально :)

hi everybody just look and study his hands years off knolage and hard work

Та же самая ошибка как и в других подобных видео) Металл не закаленный, мягкий. Хватит на 10 гаек, а потом грани сомнет. К тому же, у заводских метчиков углы которые срезают металл другие. Они правильные, не 90 градусов как у самодельной штуки. P.S. Газовой горелкой разогрей и закали в масле. Это хоть как то продлит жизнь изделию.

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

Отличная идея!

UNA EXCELENTE IDEA 👍 saludos .

Молодец! If a large diameter bolt is used a wooden bolt and nut can be cut, which is much more interesting as die ant taps for those are quite expensive. For general size small dia metal bolts and nuts one can relatively easily find cheap taps and dies.

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 :-)

I believe this tool is more for cleaning up old damaged threads rather than making complete new threads it still a good idea though

I like to use WD-40 and a drill driver. Zip it in til' it stops, zip it out and repeat. Everytime it goes deeper and further polishes the threads. The WD-40 makes it easier and help remove crud. Certainly a great way to roll your own.....good idea!

6 минут показывать как просверлить три отверстия на болте с двумя гайками. Там какой класс прочности? Это реально использовать как метчик?

Cepillo de alambre y una botella de acido muriatico... funciona para todas las medidas de tuercas, bulones, arandelas y tornillos. Ingeniosa manera de hacerme perder el tiempo.
