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.
