The way you design circuit boards is just crazy. It's insane how well you put together different disciplines of engineering. Also, you cut metal with an angle grinder like a pro.
I recently converted an old 2 stroke trimmer to 36V battery powered. Was heavily inspired by this video. I direct drive the shaft with A 24V HVAC blower motor. Overvolting to 36V with 2 18V batteries gets the the RPM on par with 2 stroke and roughly the same total power output.
Try aircraft :" grave yards" or surplus/ obsolete military : some 24 vdc 48 vdc ( just a tickled: if not doing it in the rain?) OR wait for Buydumbs electric America = SOLOR CELL CLOTHES & PROPELLER'S ON OUR UVC HATS TO KILL COVID & NOT US? OR >>> NAIL CLIPPERS & PAY PER VIEW?
pro tip: when you are cutting metal with hole saws (especially large ones) to avoid the hole saw from jamming up into the steel and splitting your hand into two, clamp the steel with some c clamps, (you will also save motor power doing this)
Interesting. Everything done properly. I have some doubts about the long-term capacity of power tools. The relatively large torque compensates for the relatively low power. The donor seems to have a ~ 1500W motor in the glory days. Does the current motor have 150W? How long does the battery last?
I'm not sure if that motor is really meant for constant duty... Like, running it at it's rated voltage for 10-15 minutes at a time. Then again I guess it would get a cooldown in between battery charge cycles.

This video is awesome. Well done. Please answer the following questions: What is the run time like with the battery you made? What is the Ah rating of the battery you made? How does the performance compare to a gas version?
@@jclowe735 Oh shitty.. cowdung.. 775 motors comes in 12v and 24v, if you want maximum power out of it, you'll need more amps and make sure you have spare batteries coz it draws lots of amps while in action.
@@chongshenchang9367I got my hands on a similar motor and it pulls 2 amps at no load (12vdc) and I pressed the Shaft down on a tiled floor to resemble a high load condition trying to stop the rotation which it didn't but started pulling 8 ish amps. Hope that helps.
Certainly helps when you have a shop with every machine imaginable. Circuit board making and 3d printing and so forth. But is really that much cheaper than just buying am battery operated one?
I like this a lot. Looked powerful the weeds you was cutting was pretty substantial. The tough stems is hard to cut and it looked to do it without a problem.
Interesting, but I think a new brush cutter would cost much less than for the new motor, buying and making parts, time used, compared to the result. How long runtime do the battery give you? How many hours did you put into it? How many parts were all new?

Yes that's correct. But the leverage to balance the rod while maneuvering left and right swing will be a problem. Motor at the lower end will make it very heavy to move. But your point is valid. Can be mounted on couple of wheels to roll on the ground thereby relieving us of the load.
@@gizmobrain I hv designed (patent pending) a single wheel Weed Cutter petrol engine assy. Safe and convenient in all respects. Any other shoulder mount brush cutter assy can also install.. Two wheel unit very inconvenient. I m also working on to replace engine to rechargeable motor assy. Looking for the exact motor. Expect to succeed.

@@danielwojtas2397 Zobacz ile obrotów ma silnik od wycieraczek. Od wkretarki chyba będzie za słaby. Tak czy inaczej będziesz musiał zastosować przekładnie. Z 24V jest tylko DC 24V 7716 który ma 3500 obrotów.
The angle on the handle is all wrong :-D You are leaning forward when using it, and that stresses your back. It's designed to be at a 90 degree angle to the main rod.

I like the way you locked the drive gear to the hub with a machine screw. It's like a keyway and a locking bolt all in one! Awesome!

Might have to do this. I have a 1kw motor from an electric lawnmower + a dead 2 stroke line trimmer 😁
Great improvisation 👌🏼 Thanks for the video.
Congratulation , crasy project very good

You have a great talent ! I enjoy your videos, thank you for making them for everyone ! God bless !
Great video
Amazing good conversation from gasoline motor to electric battery, easy to carry
Excellent work ! 👍

Great job 👍👍👍
After see this, now much understand basics of electrical tools.
Your skill is superb.nice sir

Тоже зашел почитать русский комент о том что в чем прикол этой переделки🤪🤪
В точку!🤣

I think it won't last an hour because that motor draws a lot of amps.

I don't think the goal is to make something cheap, it is rather to do something with a tool that would otherwise be garbage.
You're right
great idea

I wanna be like you
a million tools and a desire to over-complicate
That sounds like the dream
Liked you video better cutting power than some genuine battery trimmer
Great fuckin' video. Strait to work and no boring shit. THANK YOU!
Genious as usual!
That's awesome Maciej. Keep it up.
Nice work bro keep goin ♥️♥️
Nice
Few dangerous cuts and lack of fastening in the drill press. But love that work in general.
Which motor you used
He said it was a car power steering motor.
I wish you would upload every day!
Looks like it would b ok on small grass but taller stuff I think it would struggle with.
i would love to see you do a chain saw
Interested of motor, want to make small cnc spindle with beld driven 🤔
Interesting! Hello Friend
Легче нормальную электрическую готовую купить, чем так заморачиваться с переделкой, оно того не стоит.
Brawo Ty :)
Nice job what's the run time on one charge and how much does it weigh 👍😎
That is cool man
Good job well done
molto bravo, complimenti !
Impressive my friend 🙏,
Nicely done! For how long the battery hold up?
Where do you get these motors ?
Love the vids btw 👋
On the internet

That's awesome
Try copper wire instead of plastic wire for cutter. I got better result.
Superb Bro......
I Like it.....
good job, now make me one :)
So, how much use per charge with that little battery?
If you keep the motor unit near to the blade, you can avoid the rod (shaft) and its weight, so you can save much energy.
Good luck

@@gizmobrain Makita makes both but the ones with the motor near the blade handle a bigger blade so I guess they have more torque.
Not sure why unless the motor is blown cause the battery wouldn’t be as powerful or last as long

Siema gdzie można dostać taki silnik ?
Defecte
Świetna konwersja spalinowej kosy na elektryczną.
Pytanko🤔
Jaka jest jej wydajność po przebudowie?
Na długo starczyła bateria?
Wydaje mi sie ze gdzies bedzie kolo 20min 😉
A można wiedzieć bo akurat coś podobnego chce zrobić mam całą lage od kosy a jaki silnik zastosować ? Z wycieraczek czy z wkrętarki starczy ?
@@danielwojtas2397
Zobacz ile obrotów ma silnik od wycieraczek. Od wkretarki chyba będzie za słaby. Tak czy inaczej będziesz musiał zastosować przekładnie.
Z 24V jest tylko DC 24V 7716 który ma 3500 obrotów.
A jakiś silnik ze szlifierki katowej ?
I would had push button switch safety you dropped cut power. But cool tool
The angle on the handle is all wrong :-D You are leaning forward when using it, and that stresses your back. It's designed to be at a 90 degree angle to the main rod.
Why does mom always show up and ruin the party ...
Great
i dont think that motor is rated for continuous operation .... plz monitor its temperature or under volt it
Where can I buy this motor and this battery? thanks best regards
Trafiłem na ten film przypadkowo świetna robota ale jednak wolę spalinowe

is it rechargeable.?
Silniki elektryczne rozrusznika samochodowego nie są przystosowane do ciągłej pracy, przez co domyślam się, że to narzędzie szybko się zepsuje.
