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.

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.

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)

Excellent work ! 👍

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.

I love your videos. You’re so talented

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?

Brawo za pomysł! Panie Macieju, na ile czasu koszenia takiego badziewia do kolan jak na video, wystarcza ta bateria?

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?

Is there a download for the circuit board and the parts listing?

Awesome. What program do you use for pcb layout?

I wanna be like you a million tools and a desire to over-complicate That sounds like the dream

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 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.

That's awesome

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

i would love to see you do a chain saw

How long did it run for?

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

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.

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.
