Cord to Cordless 18V Brushless Angle Grinder Conversion 

That's actually quite dangerous to have a difficult to reach push button. Usually those devices on battery have two buttons, one of them is a trigger that must be pressed for it to keep working. If not... Good luck catching it when it falls...

@13:23 That bearing was onstalled incorrectly. The friction was on outer wall and you pressed in from the inner wall. Therefore the force has to transfer trough those ballbearings. Ballbearings will damage the groove where they should rotate if pressed sideways like you did.

I enjoyed watching you rebuild that grinder the way you did

Всё сделано классно, за исключением трех моментов. Нельзя запрессовывать подшипник за внутреннюю обойму, статор мотора должен фиксироваться к корпусу надёжно, иначе его будет проворачивать и кнопку с фиксацией на такие инструменты ставить нельзя, это очень опасно.

the fact that you made a more powerful motor out of two smaller ones is extraordinary.

Not really sure i like the way the bearings were pressed but the overall project and the fact you wound the motor is impressive.

Привет из России. За проделанную работу лайк. Время и ресурсы потраченные на переделку не стоят того, проще купить новую.

I genuinly love the fact when making that L bracket thing fit that they used annother angle grinder to do the work. It's fun because while you know the same result could be achieved another way it shows you that said tool type is useful, nicer, or just an easier way to do the same thing.

its amazing how nice you made this conversion and to know exactly how many turns on the wire to make, you definitely know your stuff. That said it probably would have been easier to buy an angle grinder of this type.

I had a lot of old pipes and rebar to cut up and from what I read ru-vid.comUgkxPDBfLu68o58Aw85O_J-zIFfjJARBhp-3 this would be the tool for the job. Since I had never used one, I watched a couple of youtube videos and I'm so glad I did. Some really good safety tips, which I followed, and this tool did a splendid job. One good thing to know is the weight of the tool puts just about the right amount of pressure on the metal I was cutting, so I didn't have to use a lot of pressure, which is more likely to jam the tool. It made fast work of my job.

it's quite a while since i stopping by and this channel has transformed to remaking instead of just restoring things.

When you press in bearings, you press on the outer race, not the inner race. this avoids damage to either race and/or the ball bearings in between. Other wise it was a nice job (ignoring the little boo boo of cut leads.)!

Мне понравилось когда перегородку корпуса пилил ножовкой,заодно и провод перепилил от статора))))

Crazy amount of work, but the result is really amazing

Wow wasn’t expecting you to combine 2 brushless motors! 👍👍👍

13:20 The outside must be pressed, not the inside. Pressing the inside during installation, it can cause a damaged bearing 🙏

Ignore all negative comments because you completed an amazing transformation from a clapped out, burned out piece of junk to a fresh cleanly built cordless, brushless, powerful angle grinder which almost all of the people who wrote negative comments wouldn’t be able to do themselves. It’s not always about time and cost affective value, it is a project with 100% results so ignore the haters and I am not slating the ones who have pointed out of some alternative ways which may or may not help you in future projects I don’t know, all I am saying is you have done a great job and I for one took a lot of positives from it, well done

Fantastic work, but the lack of a safety release kind of surprised me in this build. Agreed about the flat button to prevent accidental on situations, but that also makes it difficult to turn off too.

i love this series from you the way you connect the brushless motor exactly what i have thought about it

the set of stator core sheets should not be shorted, and you put it in a steel sleeve. This is the first. Secondly, bearings cannot be pressed into the inner race! Third, the wire needs to be wound carefully without twists or creases and as evenly as possible, this is not the case with you. Fourth, the general impression is that you have never held a soldering iron in your hands, not to mention rewinding motors... And everything turned out easy and simple for you))) I don’t believe you)

Reducer bearing was installed incorrectly, You should push on the outer shell not inner. Overall not bad.

nice job overall the only problem with this it's that after purchase all the necessary parts it's end up costing more than a very new cordless grinder all together plus all the work to putting everything together . But on the other hand it it's a very good to have something custum that no body else has and I really like that .

Two rebar and the battery is dead. Next video is converting cordless to corded! 😊

Too many negative comments without work? You should be ashamed. Keep up the good work, I'm waiting for your next amazing work.

Ogladałem do konca jestem pełen podziwu dla twojej wiedzy😮

I love your brushless motor conservation series🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃😃

建議電池座的方向換一下比較順手，目前電池方向和砂輪片同方向，使用起來某些角度會卡到電池，切割時的火花也可能噴到電池、可以參考makita 電動砂輪機的設計比較順手，個人小小建議

gracias a tus videos. de restauracion aprendi mucho.de todas las formas q vi de tranformar un amoladora 220 a una electrica de 18 v me quedo con esta version de video.las demas vi no llegaban a la fuerza q muestras esta.y eso q tambien tenian torno y todo las herramientas para hacer dicho proyecto.gracias a tu canal las cosas q encuentro las puedo restaurar mejor sume mucha experiencia,uno de lo mejorsitos canales q vi de este nicho

First conversion of this type I've seen. Nice. Probably the best quality 18v angle grinder out there. The older tools are just better. No shitty overload/battery/stall protection like most. Hate that on my m12 fuel die grinder, it just stops, I wish it would just bog down, instead it unexpectedly stalls suddenly. Annoying. Nice work man!

You're making such a big deal out of this. Respect to you.

The idea is not bad, but there are few revolutions... so you will make one cut of reinforcement for half an hour...😅 It's easier and faster to buy at the factory store without worrying - and it will have higher revolutions per minute than your homemade one...

Good work. An idea for second video: buy a pwm controller and pwm driven motor driver as for rc quadrocopter, with soft start, soft and immediately stop. And good idea for safety is to add a body button to stop instrument if you loose your hand over it.

I am not sure if the speed controler will last too long, especially if you force it. since it has to take the load of basicly two motors now. And usually these Controlers are used with switches wich gradually give power. All those on/offs at full power will burn it quick. It would be nice if you could use an RC testing switch wich can gradually increase power and set what speed you want. Also I am kind of a welder sometimes and i've been used the angle grinder to cut alot of metal. I've found the thin discs, the 1 mm ones to be best for cutting metal, they cut faster, cleaner, heating the material less and giving you a more precise cut. At first i thought those are only good for cutting thin metal sheets, but is good for anything you wanna cut. The only thing you have to be careful with when using them is when you cut tubes and thick pices of metal not to pinch the disc as you are grinding through the cut, those thin discs explode very fast. But even if they do if you have good eye protection and a cover for the disc you are safe. I think alot of people are afraid of those discs as they are so thin but once you learn to work with them, trust me, you will rarely use these 1.5, 2mm ones to cut anything.

Que trabajó más ingenioso, muy buena idea. Felicitaciones

Great job. You got a lathe?!?!?!? Oh my goodness.... The sky is the limit now!!!!!

Un trabajo titánico , me parece increíble lo que haces , enhorabuena por el canal. Muchas gracias por compartir , un saludo.

great! I like it very much, I have learned it!😊

Шедеврально, респект 🔥 золотые руки!

Подшипник запрессован неправильно - усилие должно быть на внешнюю обойму к тому же помят пыльник на подшипнике, а ведь он находится в самом грязном месте - вывод: скоро потребуется его замена. В целом работа проделана отличная, странно, что с подшипником вышла такая досадная ошибка.

I have been following you for a relatively long time. I am one of your followers from Egypt. I like the type of your videos

Amazing work Mr gear show 🇰🇭🇰🇭🇰🇭❤️❤️❤️❤️sending love from Cambodia 🇰🇭

Hello mister this converted is one of best work beautifully done

excellent indeed !! just one suggestion, do not mount the bearings putting pressure on to the inner race or ring when assemble that into a housing.

Parabéns o resultado final ficou espetacular, houve muita engenharia, e ficou sob medida

0:40 Magic smoke is always welcome 😂😂😂😂😂😂

You are a very good RU-vidr. ❤

Ребята, он показывает работу своего интеллекта.

Di dukung dengan pekerjaan yang sangat baik dan rapi hasil nya pun memuaskan... Selamat buat anda....

wow! kreatif banget ya mantap dan sangat terinspirasi 👍👍👍

I always jump right into the videos you publish. But this time was quite intrigued when you pressed the bearing in by pushing onto the inner ring. Why didn’t you use a socket or something so you avoid damaging it?

Nice project

nice. I've been waiting for it all the time but only you do this

1:13 there was spider living in this after what I saw the spider survived 😂😂😂

Yes very good! Only you must change the Type of switch for SAFETY precaution

The cost more expensive than buying new one. Anyway it is a success experiment..

Impressive project!

Wow you are the best DIYers👍👍👍☺️

Now that's some next level stuff

이정도 기술이면 거의 모든 기계를 고치겠네요 침 잘하시네요

As for the idea, it is wonderful and genius, but there is something that I did not like in this work, is the power button and its place is out of reach, you had to put it in one of the place of the coals that no longer exist after this update.

I love what you did here - Well done - Bravo !

I think you shorted out the laminated stator core with that sleeve you pressed in. You should have insulated it. Now it will generate a lot of eddy currents and slow down the motor, reduce the efficiency and generate heat.

Зачем проверять на корпус все три, если они проверены между собой и прозваниваются.Идея зачётная. По виду резания, мотор получился слабоват.Хотя лайк за умение мыслить и за приложенный труд.Удачи!

Super job done

thank you teacher❤❤❤ Great job, thank you brother. You are so talented

Попробуй, в следующий раз вставить, модельный двигатель 3670 или 3660 2600KV, на выходе получится примерно 10000-12500 оборотов. Вот только не знаю, штатная плата осилит такой двигатель или нет, хотя там токовый шунт, не проблема поменять. Компаунд счищается легко, заточенонной наискось одноразовой палочкой для суши.

Well done, as always surprised us with his work 😊

This is quite a great job. My respects.

Где то тихо зарыдал доктор Дью😂😂😂

Master at his craft

The idea has been mooted before. But the work is excellent, with high craftsmanship and accuracy. But there is no economic feasibility to buy a new one, the price does not differ much

Very very good😍 nice

Мощность, после такой переделки, я думаю уже не та...

That's powerful man😮

23:01 From the visual pleasure this is called great work

Thx for the video, inspiring!. Impressive work, but if you count time work time for planning, procurement, parts and tools usdage you'd better buy a new one.

Perfect,, so much like and thank you for the helpful clipe I ❤❤❤❤❤❤❤

you're just amazing. respect.

This is an enviable accomplishment! Bravo.

عمل متقن و رائع...واصل ابداعك يا فنان

Excellent Bravo 👏 You are really master Perfect 👍

Good job with all the best information and knowledge 👍

As you are using a brushless controller, maybe it would be easy to add a potentiometer and have proportional control of the RPM. Could be useful to throttle it is some situations, and not all angle grinders have that feature.

16:56 Молодец чувак! Один провод отрезал, так и остальные отрезай!?

You should build a 3D printer to build custom parts like the battery support, none of less that project is awesome

UN PROFECIONAL FELICITACIONES PORQUE TODO EL PROCESO DE PRINCIPIO A FIN EXELENTE

Incredible work, I continue to be amazed by your work with motors.

Congratulations Gear Show on this successfully completed restoration...❤️❤️❤️❤️🤟🤟🤟😘😘😘

Always Enjoy Watching Your Work

fantastic work. and a big but. the parts cost as much or more than just buying one new. and most of us dont have lathes ,presses. other tools. and your electrical knowledge

Помните мультфильм где говорят " А , сойдёт и так " ? Вот прям один в один

Wow! such drama and suspense! I can hardly wait to see the conclusion.

Excellent video 💕💕

Amazing process

Просто красавчик. Умница 👍

Wooww great modivication

Simply the BEST!!!!

you are ingenious

Awesome, I’m gonna have to try this

Wtf.. and my dumbass went out a bought a cordless one!!! 😂😂😂 Great job!! I really wish I could do stuff like this!
