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?
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'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.

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?

Brawo za pomysł! Panie Macieju, na ile czasu koszenia takiego badziewia do kolan jak na video, wystarcza ta bateria?
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.
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?
@Benny are you serious? Electric string trimmers have been around for quite some time now. Some municipalities are actually trying to remove gas powered lawn equipment all together and going all electric. You must live under a rock.
@@jerichojoe307 No, it was meant to be a rhetorical question. I actually have three - 2 petrol and one 36V electric. However, his does work pretty well for a home brew.

@@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.
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.

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!
setscrew would be better if ever need to take it apart.
Awesome project Maciej.✨ Thank you for sharing 🙏
Great improvisation 👌🏼 Thanks for the video.
Very nice. I have an old gas powered and an old 24 VDC battery powered. It was very easy to reuse the old parts.
Looking forward to next great video.

Вы правы, первый комент на русском.
Хорошая идея! Но надо иметь целую мастерскую, прямые руки и хорошую базу знаний в электротехнике!
Тоже зашел почитать русский комент о том что в чем прикол этой переделки🤪🤪
В точку!🤣
Те что делают по заводу, долго не живут.... Быстро слизывает там шлицевую пару
Might have to do this. I have a 1kw motor from an electric lawnmower + a dead 2 stroke line trimmer 😁
Interesting.

That's awesome Maciej. Keep it up.
After see this, now much understand basics of electrical tools.
You have a great talent ! I enjoy your videos, thank you for making them for everyone ! God bless !
Great video
Fantastic work, Maciej! 😃
It's infinitely better now!
Stay safe there with your family! 🖖😊
Genious as usual!
Your skill is superb.nice sir
Great fuckin' video. Strait to work and no boring shit. THANK YOU!
Nicely done! For how long the battery hold up?
Congratulation , crasy project very good
thats pretty cool man
Good boy
Great job 👍👍👍
I wish you would upload every day!
Nice job what's the run time on one charge and how much does it weigh 👍😎
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.

Which motor you used
Hey Maciej, great video as usual. So do you study mechanical and electrical engineering?
molto bravo, complimenti !
Awesome. What program do you use for pcb layout?
That is cool man
I wanna be like you
a million tools and a desire to over-complicate
That sounds like the dream

Looks like it would b ok on small grass but taller stuff I think it would struggle with.
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.
Is there a download for the circuit board and the parts listing?
i would love to see you do a chain saw
How long did it run for?
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?
I think it won't last an hour because that motor draws a lot of amps.
@@chongshenchang9367 makes you think what would a 775 DC motor do if it was used as a replacement for the gas engine.

So, how much use per charge with that little battery?
good job, now make me one :)

Few dangerous cuts and lack of fastening in the drill press. But love that work in general.

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
👍👍🛠️👏
Do they make these? It appears to work exceptionally well!

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.

A jakiś silnik ze szlifierki katowej ?
Nice
Where do you get these motors ?
Love the vids btw 👋
On the internet
Interested of motor, want to make small cnc spindle with beld driven 🤔
Where can I buy this motor and this battery? thanks best regards
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

When you were weed whacking along your bed if you walk backwards you kick all the grass out of the bed instead of kicking the grass into the bed
Great
Can someone explain to me how this "soft starter" is built? Is the start of the electric motor limited by a resistor or a capacitor?
Damn, and I thought I was smart.
Superb Bro......
I Like it.....
Very nice. Give me one piece. I will pay.

whats the rpm of that motor
What is this engine?
I would had push button switch safety you dropped cut power. But cool tool
cheaper, quieter, healthier, more durable and waaay more ecologic : a scythe.
try to use that scythe, like he idid near stones and small grass between stones. scythe is ment for large hay. use things as they are designed
Try copper wire instead of plastic wire for cutter. I got better result.
