This was a perfect video in every way no loud beginning no music while working no explanation just you playing with your awesome tools
Reminds me of the video where someone makes a chicken sandwich completely from scratch and the whole process costs them a thousand bucks.

Excellent little conversion Mr. Gear Show, as always. Great to watch you work, and also great to know that tool has a whole new lease of a way more convenient life for someone 👍👍👍. 😎
As usual you make amazing restoration videos. And to be honest, there are many restoration ideas that I can learn from your videos. stay healthy and keep working.
🤝🏻🤜🏻🤛🏻🇧🇷 Restauração de qualidade, principalmente convertendo de 220 v para 20 v a bateria, parabéns.
Yup, doesn't stall under load, great job!
Again Win!!! Beautiful work!!!
Amazing restoration job, that took some work 👍👍
Ladies and Gentlemen, gather around, gather around! Have you ever seen anything this electrifying? No, you haven't! I'm talkin' turning a corded circular saw into a cordless wonder! This is better than a two-for-one deal at Saul Goodman & Associates! I mean, come on! 220V to 20V? You're not just bending the laws of physics, you're breaking 'em, and then rewriting 'em! That's what I call real legal wizardry, my friend. If you ever need a patent for that magnificent invention, you better call Saul, baby! We're talkin' intellectual property! We're talkin' making you the next big thing since, I don't know, the invention of the wheel or something! Keep this high-voltage content coming, Gear Show! You're makin' history here!
I really like your method, very quality, greetings from Indonesia,🖐️🇮🇩🙏👍❤️❤️❤️❤️

It would have been nice if you showed the wiring. That’s the one part of this that was perhaps the most pertinent to the title of the video.
Quite impressive!

We don't get Makita's less expensive line in North America. I'm surprised that they would be in Japan. I thought they were only for less affluent markets. How is there quality?

Rotors, my least favourite part of rewinding motors. Would suggest getting some high copper brushes though, as the plain carbon ones will burn out fast, and probably are already robbing you of a good chunk of power there, and thus RPM. Could also have wound it using a shunt field, original windings would have done well enough, though of course using heavier wire and series would make it a lot more powerful.

Согласен, для двигателей постоянного тока нужно использовать только медно-графитовые щётки.

Удивительно, но литий-ионного аккумулятора достаточно для работы инструмента разработанного для 220 вольт переменного тока. Гений
Why does the motor need to be rewound? Couldn't the existing windings be used? Or would they not produce enough torque with only 18v input since they were designed for much more?

Did you check to see if the old copper windings were bad before redoing it? I'm ignorant and am seeking understanding.

как всегда хорошая работа. вопрос к вам. как вы знаете сколько мотать на якорь витков и диаметр провода, при переделке с 220 вольт на 12 вольт?

Well, with all respect, 6 amps at 20V is 120 watts. 120 watts just to spin a blade seems like a lot... Are you sure the brush angle corresponds to the magnet angle?
how long this 18v 4amp hour batery can run this.
3:06 Would it have been possible to use two bars as one and double up so there is effectively 12 bars rather than replace the commutator?
I am happy
Реально круто!!!
Отлично! Но готовый движок не проще купить?

Ryobi and makita and dewalt already make battery powered saws but good work doing it.
Does Makita Battery Have BMS?
why do you use wood in the engine? can't that start to burn with harder use of the machine?
どこの国のメーカーかよくわからん交流式丸ノコをバッテリー式に改造するという大胆な発想。コイルを巻き直すという手間をかけて、無事完成にこぎつけた。なぜかブレードはマキタ製を装着した。
Hey, totall noob here, but how do you calculate how many bars the commutator need when converting from 220v to 20v and how many turns you need?
Very intuitive but cost effects everything I'd suggest just buying a cordless one good vid though
