biggest revelation in chainsaw performance was buying a cheapo electric

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...

I find if you have a few sharpened and ready, its quick to just swap a
chain.

It never occurred to me that it *might* be possible to sharpen the blades on
a chainsaw chain in situ, because of the problem of rotating the chain slow
enough to do each tooth in turn. I suppose if you mark the teeth that are
exposed and that you have sharpened, you can run the chainsaw and stop it -
and hope that sooner or later it will stop with different teeth exposed.

Pull it round by hand, easier with an electric chainsaw.

+1. Mark the first tooth sharpened with a permanent marker. I usually
grip the handle in a workmate so that the bar is presented at a
convenient height.

IIRC the chain pulls round easily enough on my petrol chainsaw because
the centrifugal clutch is disengaged.
