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...

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

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

Crazy amount of work, but the result is really amazing

@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.

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.

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

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

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

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.

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

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

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

Ogladałem do konca jestem pełen podziwu dla twojej wiedzy😮

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

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

This is quite a great job. My respects.

Good job with all the best information and knowledge 👍

Hello mister this converted is one of best work beautifully done

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

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

Amazing process

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

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

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.

Now that's some next level stuff

Que trabajó más ingenioso, muy buena idea. Felicitaciones

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

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!

Awesome, I’m gonna have to try this

Great work 👏👏

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

Nice work!

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.

Nice info ,thanks for sharing it :)

Great work.

Very good work 👍

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

Excellent video 💕💕

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)

Master at his craft

That's powerful man😮

you're just amazing. respect.

Well done, as always surprised us with his work 😊

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.)!

Always Enjoy Watching Your Work

This is an enviable accomplishment! Bravo.

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

Gratidão GearShow! Ficou top!

Wow you are the best DIYers👍👍👍☺️

what prevents the motor from rotating itself? I see you use a setscrew between sleeve and stator, but what makes it hold on to housing?

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.

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

Nice adapting

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

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.

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.

Nice work

Just love your Videos. Great Job

Un trabajo titánico , me parece increíble

C’est excellent pour l’explication 👍✌️👏

you are ingenious

Very nice excellent work congratuñation

Шедеврально, респект 🔥 золотые руки!

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

Excellent work 👍👍👍Thank you for sharing. Be safe🇨🇦

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

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

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 .

이정도 기술이면 거의 모든 기계를 고치겠네요 침 잘하시네요

Simply the BEST!!!!

I enjoy watching and following your videos. Where do you supply/buy the empty battery boxes and equipment you use?

Exelente video y genio total.

Really cool.

the best homemade work！

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

Good job, keep it up.

Beau travail !!! Merci de partager !!

Nicely done this complicated conversion

brilliant and genius

Really good!

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

Wooww great modivication

Great Job!

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

You're a lunatic. I like your style!

This is mega step up on your restoration/upgrade game! 😍😍😍😍😍

Wow very good

عمل متقن و رائع...واصل ابداعك يا فنان

you're a champion!

Muy buen video ! Solo un detalle : por seguridad ubiese instalado un gatillo pulsador en vez de un interruptor por seguridad

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.

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

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

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

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

Great work ,,, could you publish the motors specifications or link ? also the controler 👍

good job

Thanks for sharing

Excellent Bravo 👏 You are really master Perfect 👍
