Yesterday I went to my daughter's with a load of wood. I was rewarded
with a very nice cottage pie (large portion), then, since it wasn't
raining Matt and I decided to do the right thing and cut the wood up
rather than just pile it in a corner and forget about it. Matt thought
we ought to use my chainsaw to save wearing his out (typical), so we
did. Unfortunately my chainsaw (Bosch 1750W) suddenly stopped working.
All it did was emit a loud buzz and some magic smoke. Not to worry; I've
had it for at least twenty years and it had done a lot of work, and the
oiler didn't work and the chain tensioner only just worked. (Later I
dismantled it out of curiosity and found that the front motor bearing
had seized absolutely solid. But surprisingly the gear wheels showed
very little wear and the motor brushes were still quite good.)
I don't know whether to get a petrol or electric chain saw. If electric
a constraint is that I want it to work from the genny, which is 2kW. The
bigger chainsaws are 2.5kW.

A motor is an inductive load.....

Even if you replaced the genny with a 2.5 kW version or found a chainsaw
rated at 2.00 kW, it will still not work due to motors being an
inductive load. (You need a higher start power before it then settles down.

Plus there is power factor to think of.

Another case of an older design being more robust than a new one then I'd
say, I can recall a guy trying what you wanted to do, but in his case it was
a power saw, and it just tripped the generator every time it was turned on.

With all the concern about exhaust pollution from petrol and diesel engines,
how long will it be before two-stroke petrol-engined cars, bikes and power

initially for new sales and later for use?

I think that not seeing or smelling any 'exhaust' doesn't help us
remember we are still producing pollution.

The same reason we (had to) deal with the London smogs, are now
dealing with 'other' pollution in the same place (and similarly around
the world) and make domestic gas smells so we are reminded it's there.

It's the same thing with electric machines of course, assuming they
aren't only using generation techniques that don't (directly) burn
fossil fuels, it's just that the pollution is even further out of
sight (and so further out of mind).

It's like when we 'throw something away', where is that exactly and of
course 'most people' don't care as long as they don't have it any
more. ;-)

Here, a gentleman in the video, measures an electric chainsaw.
With the chain not moving, the peak input current is 50A on the
120V powered saw. The normal operating current is more likely
to be in the 15A range. That's at least a 3X multiplier.

https://www.tek.com/how-to/inrush-cu...ctric-chainsaw

The generator must be scaled a bit, to handle that surge
without stalling. If the generator is the same size as the
load, maybe it will stall out when you pull the trigger.

There is a Makita chainsaw with a "slow start" feature and
"motor current burnout prevention" type feature. But you're
paying the price of two or three chainsaws, just to make
your generator hold up.

The highest stall current I know of, is electric motors
that draw 10X the current at zero RPM. The electric chainsaw
measured 3X. Refrigerators, the estimate for the compressor,
is a stall load of 5X at startup. And an oversized generator
can help, with the transient load.

Some electrical loads, will even trip the the generator protection
device when the load is connected. So there is that possibility
to consider as well.

Daughter tried some chainsaw carving at an arb show she had a stand at
using my cheap electric chainsaw and one of my 3KW generators and I
think that worked ok (as far as the saw functioning ok, rather than
being nice / suitable for carving compared with her Stihl carving saw,
certainly with the (stock) bar on the electric).

At least the generator could be put a distance away from the visitors
making the carving bit slightly greener (4/ genny) and quieter (and
probably less vibration).

Yes my first attempt at designing a drill speed control using a triac ended
in tears due to the strange effects of inductance, as I recall.

Many power tools have a soft start from EU regulations.

Generator MCBs should be tolerant of short term transients.

Most of the time you will get away with the start current from power tools.

Also worth considering battery powered ones these days - especially if

When we moved into our new house, we found that the previous owners had gone
a bit OTT with vigorously spreading conifers around the garden. I had to
prune or even cut down some of them. Having tried a bow saw (which the
previous people left) and a tenon saw, both of which kept binding in the
wood, I bought a battery-powered chainsaw. I know which of those three I'd
prefer to use ;-)

But you still need to exercise and you either do that futiley g by
walking nowhere and back (as we often to for the dog), doing similar
in a gym [1] or allow some jobs to keep you fit.

I manually split (with a manual hydraulic splitter, rather than a
powered one) a few one tonne bags worth of ash, mostly for that
reason.

If you are doing something *just* to keep fit, that's the only
incentive. If you have a stack of timber that *needs* splitting then
you plod on though it till it's done. You are retired so there is no
rush.

In the old days even just 'living' needed quite a bit of manual
effort, manual jobs, few home appliances, not everone could afford
mechanised transport so would walk or cycle and you even had to get up
and press a button to turn over the channel on your TV. ;-)

Now you don't even have to press a button on a remote to turn your
lights on or order some shopping to be delivered straight to your
freezer the next day.

I've seen suggestion of making jobs like vacuuming into more of an
exercise than it is by maybe stretching rather than stepping or by
leaving the bag of shopping on the floor and lifting each thing into
the cupboards, one_at_a_time.

Then I would certainly consider a AKE 30 LI.

I don't know if they do a longer model, but it is an Oregon chain and I
suspect that longer Oregon bars would also fit.

Personally I would now never consider a corded chainsaw, which
simplifies the decision process. I have both cordless (smaller) and
two-stroke (larger). The latter is 20 years old and sometimes reluctant
to start, I have been very impressed with the amount that I can manage
with my "20 volt" Lidl (with about a 10 inch bar).

What size bar do you need?

Yes, that is the main piece of information not supplied by the OP.


Also worth considering battery powered ones these days - especially if
you are already "bought into" an 18V battery platform. (and you can
always charge them from the genny).


Personally I would now never consider a corded chainsaw, which
simplifies the decision process. I have both cordless (smaller) and
two-stroke (larger). The latter is 20 years old and sometimes reluctant
to start, I have been very impressed with the amount that I can manage
with my "20 volt" Lidl (with about a 10 inch bar).

Yup same here - corded would be too much of a PITA.

I use a 14" Makita 45cc petrol saw, and a 10" pruner saw on the end of
my Stilh power head, however I am toying with getting a "top handled"
saw for safer ladder / platform work - going 36V for that seems like an
obvious choice.

(biggest revelation in chainsaw performance was buying a cheapo electric
chain sharpener though)

So far I've gone the three chains for £24 route, and only managed to
dull one.

I find that you need to sharpen about every hour, and it takes about ten
minutes, and the file lasts about a chainsaw week at best.

Electric sharpeners mean you have to take the sodding chain off and that
takes even longer...

My son-in-law's chainsaw was cutting very badly.Ten minutes with my 12V
sharpener and he couldn't believe the difference.

That's interesting. Which product?

Although manual sharpening is a bit of a fiddle, I usually find that
three to five strokes of the round file per tooth is all you need,
without bothering with the other file. So it really does not take long
for a ten inch bar.

I find it easier to just have a stash of sharp chains on hand to swap in
as required. Also the powered sharpener seems to be able to get a much
sharper edge than I can manage with the file.
