Cord to Cordless 18V Brushless Angle Grinder Conversion

[@science7542]

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

[@mihkus]

How is that more power if the controller has fixed output current? It lost power because the windings are now rated for ~2x higher voltage...

[@engenhokas69]

@@mihkus no they not, he used thicker wire to compensate for longer turns. and yes, motor size gives you the torque that he needs to do his work. What he lost is the KVA of the engine, 1000KVA is 1000RPM per given volt, now with lower resistance you will need more voltage to achieve the same RPM as before, but then again he gained torque and that's more usefull here that even more RPM, it's good as is.

[@Maungateitei]

What T H!!!! Why you think box of stupidly delicate electronic rubbish better than brush and armature that last lifetime. Be much easier and better result if you convert to low voltage brushed dc motor.

[@michaelmitchell1496]

I enjoyed watching you rebuild that grinder the way you did

[@maxheadroom1506]

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.

[@gear_show]

Thank you very much!

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

[@madvelila]

@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.

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

[@BDFireFist]

I also agree with you about the bearing part man, it ain't very good for the them to be pressed that way, the should be pressed from the outer walls.

[@AdamDitheridge]

Yep....always press a bearing in using the outer race..... But brilliant project none the less.

[@QuockhanhPham20]

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

[@yakine13]

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...

[@suecordon8763]

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

[@Nitrofan_Kerm]

[@abdullah.a3237]

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

[@massaid88]

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

[@nianiucha21]

Ogladałem do konca jestem pełen podziwu dla twojej wiedzy😮

[@scottyhankemeier9380]

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!

[@BloodSprite-tan]

you should probably buy a better die grinder then?

[@bubisav123]

Crazy amount of work, but the result is really amazing

[@mikeflight9]

This video shows your skill and knowledge, and not for someone like myself to try and duplicate any of it. 👍 On the other hand, it would be much cheaper to buy a battery powered angle grinder. 😂

[@stuartodell1709]

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.)!

[@gear_show]

That is excellent tips, I do appreciate that.

[@andreykuznecov9635]

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.

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.

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.

can you post links to the brushless motors, the controller board, and the battery adapter? I am interested in replicating this conversion

[@stephanieking9242]

I had a lot of old pipes and rebar to cut up and from what I read kzbin.infoUgkxPDBfLu68o58Aw85O_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.

[@laurentmouchague4161]

Merci quantin toujours au top la team.....

[@dogukancil5128]

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.

[@francoisguyot9770]

Awesome demonstration on why I will NOT try repeating this type of conversion. It's just not worthy and it's way more expensive than buying an old grinder with NiCad battery and convert it to Lithium. If I must go cordless, I would get a Hercules 20V grinder from Harbor Freight for $80, just $10 more than the corded one. They even give 20% off on specific days, like father's day. Otherwise I got to give it to him for his determination. However not too many people have a lathe or machine shop, or even the time ...to perform these conversions.

[@rishabhgupta3562]

[@LuisTeixeira]

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.

[@ВладимирВинокуров-ь2в]

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)
