It doesn't matter what wood you're working in, gravity is the same. I'll have take another couple of minutes out of my day and do another couple of sketches to prove it . I was waiting for you guys to show how with a diagram how it's possible but the lead paint levels must have been a bit higher over your way than here, I hoping they won't be too complex to understand, an engineer would grasp them easily.
Tanks
And there it is, yer an engineer, or at least claim to be, and a surveyor, so you deal in the hard set rules of bureaucracy. If its not taken out of the box and used to beat you with it your never going to understand.
Swingin trees is real life, not paper, not a computer sketch thought up by some college grad for a doctorate in theoretical timber falling...
4 days a week, soon to be 3 I'm a machinist, like the real kind, its my job to take some engineers pipe dream and make it a reality, and engineers have earned a reputation of having no basis in reality sorry but its true.
Does not matter if its dirt projects, aircraft or space craft, this **** they come up with is simply astounding in its ineffectiveness, overthought, over toleranced, and expensiveness. When if they just shut up about their college degree in whatever, and spend 15 minutes with the lowly grunts they could improve things 10 fold daily...
Rant over...
to reiterate, the first cut in the soft dutch, effectively changes the lean of the tree, from nearly 180, to closer to 150, the second to 100, the third if needed gets you in the 30 deg range notice how it exponentially increases. Think of each step of the soft dutch as another face cut, each one directing the tree more and more away from its natural lean.
In essence you say you can only fall them max 90 deg from the lean or C.O.G (lean is easier to type by the way...) but that first dutch is only 90 deg to the lean, or less, and if we where to then hypothetically make a face from that cut, the tree would then fallow that face yes? The steps are merely continuing that process around to where you want it to ultimately fall, its "final destination" if you will. By making the back cut you allow the tree to both pick up momentum, and turn into each new "face" or step, just like falling a tree 90 to its lean, but doing it 5 or so times in just a a few seconds.
Further more. By making steps, rather then full face cuts, we can stop the movement and then steer it towards the new direction, incrementally. (though stopping isn't really the right word... cause stopping movement sort of ruins a good step dutch swing, remember its about the momentum objects in motion or some bull **** hey another enginear...)
And honestly falling timber is dangerous, but this method is fairly safe in comparison to some others, the hold wood, the wood facing you, the "faller" never gets touched by the saw, unlike a conventional fall em with the lean method, where once the face has been cut up, all the support of the compression wood is gone and suddenly there is massive weight on the tension "back" wood, which is then weakened by sawing into it, sometimes causing a chair.
In other words go find yerself some annoying leaner out in the bushes somewheres and try it, give yerself a whole bunch of escape paths and bring some ass paper...
