    The muffler came loose in my ms440. One of the two screws inside the muffler just disappeared. Pretty worrying. But no damage seen, so I guess that the screw found its way out.\\:D/

    According to the comment, the beams under the stump grinder are 4"x4", a lot stronger than a 2x4. The stump grinder went on the ice to grind the world biggest ice carousel. Here's a smaller one (last year): <iframe width="560" height="315" src="https://www.youtube.com/embed/Ewz7ZSdr5T8" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>

    Wd40 evaporates soon to about nothing and doesn't really lubricate. So it can't help long term. But it's very fluid and finds its way in the mechanisms, dilutes the old oil and grease, mobilizes the gummed deposits if there is some move. I use it mostly to clean and to flush the bearings, sliders and the mobile parts. Put the Wd40 on the top side, work a little the pieces, put it again with the same position, continuing working the mechanism. The Wd40 will wash out the crud. Then add some oil at the same point, it will be diluted and thinned by the wd40 already there, so it penetrates easily in a cleaner area and this actually lubricates your stuff.

    I love this trick too. You can have as many wedges as you want for bucking a top bind trunk, and not need to fight to get back a plastic wedge. It doesn't work well if the log tends to rotate when it settle though. I tried it too for felling a leaning tree (rigged in whole) from a cluster, but that put too much load on it. But it's good for alaping the big stumps.

    Me too. It seems that most people are "clinical" lurkers and want both to feel fear (but not be involved in) and to see others in the most critical situation as possible. So the producers push heavily on that to make money. It's easy when the lurkers know nothing about the subject. I can't understand how we are "wired". One of the remarkable points of the human being as an evolved specie is too feel empathy, mandatory for the social function. How is that possible to have the both sentiments? That' incomprehensible.

    Refills are actually a good thing with such an hard task: they allows you to relax a little time to time. If you "run" continuously, you are more likely able to burn you out. Take your time.

    All I know is that Firefox loads its upgrades automatically. But my pc is on windows xp3, maybe the recent softwares have some compatibility problem with the "old" systems. Thunderbird gives me fits too, acting like Firefox with stacking unneeded memory. When Firefox turns dumb, usually Thunderbird too. Hard shutting Firefox (and retrieving plenty of memory) gives me back the hand on my pc, but not on Thunderbird which stays lost (and frost) and I have to hard shut it too. Then, reopening both and it's fine. :? A little annoying...

    It loads better, but it ends as usual, my pc freezes completely, almost nothing works anymore. Actually, I found that my Firefox seems dumb : it can't manage the memory properly and it keeps active all it had previously loaded, even what is no more on the screen. Gif or many vid on youtube do the same, not enough usable memory. Firefox runs in circle, trashing its own data but keeping the useless ones. Stupid. I have to hard shut Firefox to retrieve the memory.

    The bent radius thing is a data given by the rope manufacturers, either steel or textile rope. It doesn't say that you will drop your load with a tight radius, but that the load allowed on a rope decreases as the radius is smaller. So the WLL is reduced by a certain amount. The recommended radius is the value with an acceptable reduction. Going farer than that is possible but at the cost of a substantial loss of both rigging capacity and durability. You could very well never see the difference, because it's hidden in the safety margin, at least if you don't push the thing too far. But your safety margin is no longer 7 as it should be but more like 5 or less. That lives less room for the other hazards affecting the rope. I'm afraid you do. It isn't a matter of load, length, size, or even angle, but just curvature. Just look at it closely, not the wide view of all the device, but follow bit by bit the path of the rope. On a pulley, the rope first comes straight, then bends and takes the shape of the pulley, rides all over the pulley with the same bend (constant radius of the groove), then lives the pulley and straightens back. On the three stacked rings, the rope first comes straight, then bends and takes the shape of the first ring (way smaller radius than the pulley). After a bit of riding on the ring, the rope lives it and straightens for one inch or so, then the rope finds the second ring, bends again on it to take its shape and slides to the other side. Here, the rope lives the second ring and straightens for the second time, taking a small travel in the air. The rope finds the third ring, bends again to take its shape as previously, slides on it for a bit, finally lives it and straightens for the third time. You can see that the rope only took the shape of the rings individually and was never close to the shape of the first case with the pulley, even if the overall size of the stack can match the size of the pulley. Now, for the flattened pulley, the rope actually sees two tight bend radius on the edges of the flat spot.

    That's one of many things which amazes me that many people don't want to understand and we find these misconceptions again and again. Stacking 2 or 3 rings only divides the bend of the rope in 2 or 3 parts, separated by straight segment(s). But it's always the same bend. It's even worse than one ring for the rope because the fibers slide against each others 4 or 6 time instead of 2. The rope actually alternates bending and straightening, so the internal wear increases.

    The thin cut resistant gloves work well for the straight blades with a continuous cutting edge, not for the serrated blades or even more the long sharp teeth like the Sylky's. They aren't against the punctures at all and the handsaw's teeth act nearly as needles, they just go through it, between the fibers instead of across them. The teeth find the skin before they travel enough through the fibers to be stopped. The deep of the wound can be almost the length of the teeth, even if the fibers aren't ripped by a vigorous strike. I tested them at my beginnings, at the same time I tested the sylky's sharpness :( I didn't find that it worths the cost, either for protection or for wear, compared to cheaper gloves.

    I needed a torque-wrench in 3/8" to put the new knifes on my chipper, but I had only one in 1/2". So I take my regular 3/8" socket wrench, did a simple math about levers, and pulled the end of the handle with a small electronic scale for luggage, right at 90*. About 17 kg on a 18cm handle for a 31 N.m. A little care is needed to do it (do not slip, the knife's edge isn't far, although it's factory dull), but it worked well. That's funny to look at the progression of the number as you increase the load : the angular displacement doesn't seem to be so obviously correlated to the applied torque.

    Thanks to bring back the song in my head !:D Yes, it does. But Codit isn't involved here though. We can't speak really about damage, as the oak wasn't wounded (yet), only disrupted locally in its growth. It was working on it to overcome this annoyance and it seems (first look) that there wasn't any dead area by the girdling. Maybe that could come, maybe not. Actually we come after the battle, as the tree will soon be all dead.

    Thanks all of you. Fear of dentist, yes, that's why my mouth is in such a bad shape, following a painful crown laying. But I pushed it to a point way worser than it was at that time. My new (to me) chipper is a toy for most of the treemen here. That's the Rabaud Xylochip 100DA. http://www.rabaud.com/fr/materiels/broyeur-de-branches/broyeurs-de-branches-autotracte-xylochip-100da.html?filiere=forestiere It's tinny enough to pass through most of the garden gates, but should have a solid appetite for its size. It's self propelled and has a feeding roller. I was tired to fight the limbs to be shredded and to drag by hand my even more small previous one.

    I like butter and jelly on the bread, but I don't want to taste the plain butter like that, nor I want to get my fingers, lips, beard, bowl, all covered by the said butter. I had a friend at school, a fat guy. Once in the dinning hall, he took an individual butter portion, unfolded it and put it directly in his mouth, contentiously chewing it (open mouth of course). Just seeing him to do that, it almost made me puke. I still recall the feeling about 40 years later.

    Not a so good year for me. - My (so-called) buddy, and main customer, let me down before the spring without an explanation, and plays the dead to not pay me about 10 months of work. - A moron hit the back doors of my van, not enough value to repair it, so I had to buy an other one, well over the price paid by the insurance for the previous one. - I lurked since a year and half for an interesting small chipper, (I saw only 2 on the market during this time). I got it at a remote auction from a business crash, very happy, but it turns out that the maintenance wasn't top. Beside some secondary things, the hydraulic system is trashed, brown oil, steel and aluminum chips everywhere; so, a new pump and 2 new translation motors are required, at least, maybe the actuators. - I wounded myself a finger with the ms440 in july, skin and nail graft required. The main cause of the accident was a strangled nerve at my left elbow, leading to the loss of sensitivity and almost all the local muscle's control in my hand. I got that fixed too (I should have done that many months ago), so even more down time, but my hand begins to feel better. - I had to begin some heavy work on my teeth, with deep infections in my jaws from years of lack of care (again). Finally it ends on a good note (I guess), as I'll become a grandfather this spring. I surely wasn't prepared for that, the new worries, getting older and so on... but who care, a new life comes in:)

    I bet that the splitting with the maul will be almost impossible, due to the bracing action from the extremely tight rope. There isn't much more elasticity left in the embedded rope to allow opening the split. Plus the convoluted fibers. I'd cut lengthwise with the saw.
