2 chains at £15 each is £30. The saw is only £50. So to break even there would need to
be a 60%
chance of the original chain killing it.

I'm still undecided whether to go Titan or something 2-3 x the price.

As you like sharpening things and could probably get the time down with practice,
unless you're super-fit, providing you had 2 sharp chains before the start of a
job I can't see you outlasting the saw - over a day's sawing at least.

Maybe after 20 or 30 such days the saw may give up, but you'll
have had your money's worth by then.

Someone on here mentioned plastic gears and I don't know whether
they were serious or not.

It was me, and I was serious - the cheap electric chainsaw died in a
couple of hours use, and on examination the problem turned out to be
melted plastic bits.

All the thing is, is an electric motor, driving a wheel which engages the chain
which runs around the arm. That and the braking mechanisms. By the very
nature of chainsaws its difficult to see why anyone would need to run one
continuously for over a minute say. Except up a tree lopping small stuff
obviouisly, but that's not we're talking about here.

The one which died was being used to chop up wood on the ground, much
like NT is proposing to do, albeit with smaller logs. The duty cycle was
far too high for the device - and I reckon NT's project will present
similar or worse.
