Houses and Home Ownership

My guess is that it’s simply a matter of weight. If you want your electric chainsaw to be as nimble as the V8 one in the video above, then sure. If you actually want to be able to carry it…

I guess something could be arranged where the batteries are in a large block that just sits on the ground and then there is a power cord going to the actual saw. Or maybe a backpack you wear like Ghostbusters.

This is actually what they do for high powered flashes in photo studios. Giant power supply/battery/controller that sits on the floor. Connect all the lights to it. Lights are now just bulbs on strings.

One thing to consider with electric. They have consistent torque within their rpm range. Meaning they’re just as strong at slower speeds and will eat through protection. This:

will not happen.


#324

Actually no, they have more torque down low. Power is defined as Torque * RPM, and what electric motors have is more consistent power. On the other hand, there’s a lot less momentum in the system as an electric motor doesn’t have a crankshaft with heavy counterweights.


#325

There are no electric saws on the market (at least, generally available) that suit all of my needs. I need to be able to fell and buck hardwoods (oak, maple, and cherry) up to ~24" in diameter, and I need it to not take all day. That’s pretty much exclusively the purview of a gas saw, and generally something in the 55+ cc range.

My old saw was ~3.2 hp and could drive an 18" bar. I’m looking at ~3.8 - 4.3 hp to drive a 24" bar.

We do have a battery-operated saw for limbing purposes.

The other problem with the plug-in electric is that I have 3.5 acres of land, and what if I need to take care of something 400’ from the nearest outlet?

I’ve seen a few professional loggers working recently on shows like This Old House. They didn’t have giant chainsaws, they just made 2 cuts.


#327

“Just make two cuts” means “do twice as much work.” :slight_smile:

This is particularly annoying when you’re sawing through a 22" chunk of rock maple and have been for hours. Your back tends to get angry.


#328

It did not take them long, there seems to be a fair amount of technique to the process.


#329

Ooooh burn!

You may WANT that to happen, for safety reasons.


#331

Yeah, cutting with a bar smaller than your total cutting length is finicky work, but doable. It also involves lots of bending over and pushing for a long time (and you do a lot more pushing with a lighter and lower power saw), which murders my back when I’m at it for like 4 or so hours at a time.


#332

That was my point, I was saying electric saws will murder you if you accident.


#333

So, electric saws are torquey as hell, sure, but a powerful saw at full speed is as much or moreso.

The Makita UC4051A is one of the heaviest-duty electric saws on the market. At 15 amps and 120V, it clocks in at 1.8 kW/2.4 hp. That’s a lot of power in a small package.

Its chain speed is 2900 FPM. To convert that to RPM, we can crunch numbers. The pitch of that saw is 3/8", and with 7 teeth on the sprocket, we get 5.25" of chain movement per revolution (since each drive link covers its pitch twice per revolution). That means the saw is going at 6600 RPM while generating 2.4 hp, or 1.9 ft-lbs of torque.

That’s a lot of damn torque for a chainsaw.

Meanwhile, the Husqvarna 455 Rancher puts out 3.5 hp at 9000 RPM, or 2 ft-lbs of torque.

The 465 Rancher is 4.4 hp at 9600 RPM, or 2.4 ft-lbs of torque.

So, if those chaps can stop full-speed rancher saws, they can probably stop the most powerful electric saws available.

No, electric saws will not murder you deader than gas saws.

EDIT: My bad, 6 teeth on the Makita sprocket, meaning 7733 RPM and 2.4 hp, or 1.6 ft-lbs.

Ah well fair enough, I did not do my own research and was repeating something I had heard. I appreciate you making me correct in the future.


#335

I mean I didn’t care about any of this until I had 2.5 acres of woods with giant maple trees tossing limbs into the backyard, so doing your own research is pointless for most people.


#336

Fun facts, if you see that up-and-out style of pipe on a car, they’re called “Hater Pipes.”


#337

I thought those were zoomies.


#338

Difference it the collector. Zoomies are straight(well, “Straight”, but you know what I mean) with no collector, Hater pipes have a collector.

The one different one I’ve seen is that the Roadkill guys call the hood-pipe coming right off the turbo on the Rotsun a “Hater pipe”, but I’ve only ever heard that called a Screamer pipe.


#339

Guys, I’m very excited about this new fridge I just ordered.


#340

Ooooooooh shiny. Old one died, or just decided to get something nice?


#341

The old one smelled like burning/electrical fire for a few minutes and now we don’t trust it. Hasn’t done it since, but house fire is high on my list of “don’t roll those fucking dice.”
