    In France we have a union for the treework, but actually it's like an association of the biggest actors of the trade, speaking with the government, pushing the rules... Some very motivated arborists tried a few years ago to build up an union for the small guys, either workers or owners (first difficulty: putting both together !), to counterbalance the previous one and to give a voice to all the independents and the small companies. They got good words and good wishes, but that's about all. Very few people were really ready to invest a massive amount of their time to help sorting it out. Finally, they gave up.

    I don't think that the treeman's chipper can do a good job for you. It is just not made for that. The properties of the material to be shredded plays an essential part in the conception of a machine. The limbs and logs hold themselves in front of the knifes, allowing the small bits to be cut off. When the piece of wood becomes too short or too thin, nothing hold it anymore and it is directly shallowed. Not necessarily in a pretty shape, but still, it goes throw. Some shredders have a screen between the rotor and the exhaust chute to limit that. If the big or long chunks found their way through the chipper the first time, there is a great chance that a good bunch of them will do it again the second time. Beside of that, the small bits already cut to size will go through too, barely untouched (good thing for your project), but by an enormous quantity at the same time, so the expeller system is overflowed and the chute is clogged (often, it's just an fan-like system on our machines, sending an air flow to push out the chips). Even if you can adjust optimally the flow rate of the raw chips at the entrance, in fact you will spend a big amount of fuel for too small of a gain at the end. I agree with MrMoon5shine, first I'd pass the chips pile by a screener to sort out the "good" chips. I think that would be the most cost effective, due to the high percentage of material usable as is. Then, you can find what to do with the refusal : regrind (but it's even more hard to find an economical solution), rot, burn, horse litter (maybe)... An other advantage of the screener, it allows you to not be too worried with the foreign materials in the chips, contrary to the delicate edges of the chipper

    That seems to be the steel itself to me, a transversal crack with a very small volcano shape and a hole in the middle I was at my parent's home for a week and can't do the pic thing to show that.

    I saw that a few days ago for the sailors. It could be interesting, no cut needed. That's a rope carabiner releasable, even under load. It's available in 3 sizes, as a finished product (public sell) or "naked" to be integrated in a splice ( pro sell). <iframe width="560" height="315" src="https://www.youtube.com/embed/69Ea4LJlUG0" frameborder="0" allowfullscreen></iframe> http://www.bateaux.com/article/24800/mousqueton-largable-textile-nodus-enfin-disponible The maker : http://www.nodusfactory.com/produit/mousqueton-m-t-close-smile/

    Yes, but I can see more than the bulge, there is a small crack in the middle too.

    He put plenty of care in his turn, he had to know that he dragged this strange trailer. My guess is the whelled chair ran out of power and the woman on it is too fat to be able to climb in the truck.

    In the link, they say that the tree shatered when she hit the ground. I guess there is a lot of rot and not so much sound wood. Moreover, I heard that the giant sequoia has a wood with poor qualities and no industrial use (basic information viewed from very far).

    Better to have 2 triggers : The first one activates the mechanism shooting the cord around the limb, catching it back and tending it. The second one cuts/releases the cord. :D Well...isn't there someone said KISS ?:/:

    I keep my chainsaw pants all the time, even back at home. It becomes natural. It's good for home work too, because it gives you a nice cushion on your legs against all the little scratches and bumps. I feel naked in jeans now !

    LOL @ Butch ! That's an important point here and not an easy one to solve : passing around the limb and tying back on the device with only one (gloved) hand. It has to be easy and quick to be actually used (and secure of course). If you need both bare hands to attach the cord, it downgrades seriously the usefulness of your device in the average job. It needs some brainstorming here.

    There is like a step ladder along the rail on the outside (link 2 pic 1), maybe one step for 20" or 2feet. Not very practical for the customers. The firefighters seems to came from the top of the mast ( pics 4 and 7). You can see there a steel platform just beside the step ladder's top and a man hole a little farther to the right. I bet there's an other ladder inside the mast, and probably an elevator to get to the machinery room on top (pic 9). But for the midway trapped visitors, I suppose that it was as much impractical to reach than the ground.

    Couldn't be that a case for a back cut first type of cut? Cut the rear with setting as many wedges as possible in the width, stop to keep a fat hinge at the end. Then cut the face, as usual with 2 cuts if the wound is sound enough, or with many small cuts to "grind" the trunk if the wood is too punky and tends to settle on the bar (and be ready to run). A rope should be a better idea though.

    That's an interesting way to rig the odd shaped logs, but it needs a so hollowed trunk that I most likely would be frozen by fair up there.

    Actually, there's one move relatively friendly for the wrist/arm. It's for the limbs on the opposite side of the trunk or above you, by letting them go forward away from you, not to the side. The hand keeps its grip in line with the limb and your arm, like with an axe splitting fire logs. But there's a problem, the forearm is just in the path of the chainsaw or the handsaw. That could be a concern...:/:
