Whenever I try that the chainsaw jams in the cut . . .

Me too. I think they put a wedge in the cut. Pretty impressive stuff by those loggers.

I realise that they 'prioritise' their cuts, but getting the timber to fall cleanly away from the cutter is mighty impressive (without stay-ropes).
How do they estimate the weight balance of the foliage and the windage?

Experience, I guess. I wouldn't want to learn the hard way!

As enthusiastic lads of 68 and 71 we retired pilots in Norfolk....Put the smiley face in first to sight the direction of the fall...then the last horizontal cut about an inch higher than the horizontal first cut...you can tap in a plastic wedge behind the chainsaw blade to control the tipping and fall... or if you do not have a plastic wedge we use on medium size trees say up to 4 foot diameter (nothying like the Canadian monsters) a long lenghth of nylon rope attached about 30 feet up the trunk and a helper to keep it tensioned and pulled to keep the cut open and direct the fall as it falls...we also very carefully consider the wind direction and its effect and always have at least two escape routes cleared.
We never hurry (we cant!) and so far have been lucky.
A retired pilot mate of 66 went up a tree with his chain saw and managed to fall out of it ( we never take our chain saw up a ladder) and he ended up in the Norfolk & Norwich hospital....his neighbour 82 visited him and told him pilots should not go up ladders aged over 55 and he had finished off the job for him!....all good adrenalin if you do not fancy the care home option.

I've 'studied' aerial chainsaw topiary, having myself indulged (to a degree) and have watched my own trees being pruned periodically by professionals providing clearance for HT electricity lines. Of course the scale is several degrees away from that shown in the videos, and the larger limbs were taken down in sections using rope tethers.

the tool of choice is the 100cc Stihl 066 magnum with a 36 or 42 inch barI'm surprised that the engine is only 100cc (mine is 94cc . . . )

I'm also surprised that they aren't wearing kevlar-lined gloves

And this looks pretty dangerous too:- http://www.liveleak.com/view?i=9c0_1189805609
I wonder how many rollover accidents they have?
