Eydon poppin kettle here - fabulous gadget. Combine with a thermos "jar" and instant noodles for a tasty woods treat!

Seconded. I carry a leatherman squirt at least, which is kind of like a lucky charm I suppose. Like the doctor who performed a tracheotomy on a plane with his swiss army knife classic - could save a life. The squirt coupled with a AAA flashlight on a ring is pretty much minimal daily carry for me anyway. I have a needle and some duct tape in my wallet as well. I couldn't ware a lucky charm anyway, can't stand having anything attached to my extremities or around my neck. Thought - are tattoos lucky charms? I think that was kind of their purpose in the beginning right?

Wouldnt a generic filter do the job?

Ok so then it would be 300kg WWL on one leg, or 600kg if using it DdRT. Thats a strong wee pulley. If its considered to be a rigging device, that is. I will consider it PPE anyway. Only want to hoist a double glazed unit into place with a pair if them, so they'll be well within their limits. Thanks for your replies
-
Nice one, thanks. I just checked my climbing pulley (small one) it actually says on the pulley - 30kn total, 15kn on each leg. Thats a lot for a tiny pulley! I suppose the WWL then would be a fifth of that, so them little pulleys are really only supposed to be used for hoisting 150kg with one leg tied off, which makes sense, given the size of the thing.

By the way, Jap knotweed shoots are edible - delicious tastes like mild rhubarb. My next door neighbour used to make crumble with it, and is still going strong. The Japanese make tea from the leaves.

Just occurred to me, does the working load limit of a pulley indicate the total max load of the pulley or just one fall? I have a couple of 4-tonn snatch blocks, but the shackles that came attached to the blocks are WLL 6-tonn. Don't know if that means anything. If I haul an object with my block, with one fall of the rope being pulled by a winch and the other fall attached to an anchor point, and I put 4 tons of force on the rope with the winch, then the total load on the block is 8 tonns. I would have presumed the WWL is that of the mechanical advantage, not the winch pull. Makes me wonder, if I am correct, if people are sometimes overloading their pulleys in the tree. Like a 15kn alloy pulley would have a WWL of 150kg approx - right? This means that if the rope is tied off to the base of the tree, then the WWL should be halved - giving 75kg? Surely that can't be right.

Do trees have feelings too?
Haironyourchest replied to kevinjohnsonmbe's topic in Training & education
I heard an old belief in Ireland is if you tell a tree you're going to fell it, the other trees around will faint with shock. So you must always tell a neighbouring tree that you intend to fell it - not the actual tree - so your actual target will faint and you can fell it while it's unconscious to spare it the pain. -

I'll just leave this here....(Lady has a relationship with a tree called "Tim" and wants to marry him) https://plantintelligence.wordpress.com/2015/03/23/im-in-love-with-a-tree-its-the-best-sex-i-ever-had/ -

I can't remember the concentration, but a search would reveal it. I think spraying after cutting is maybe not going to work, as roundup is absorbed through the leaves and the plant has to be alive and circulating in order to carry the roundup to the roots. I believe when cut, the capillaries in the stem close up but I could be wrong. Cutting at full growth, then spraying the next growth is also said to be effective. There's a lot of energy stored in the rhyzome system, so the idea is to let the plant put that energy into growth, cut the growth before the plant can start storing energy again, and repeat, gradually depleting the energy stores till the plant gives up and dies. Can be done without chemicals, just takes vigilance and time.
-
Glyphosate is effective if injected directly into the stem at the right time of growth and in the right concentration. Every single stem has to be treated. You could do this yourself if you buy the special injector (£400?) but it can be done painstakingly with a livestock syringe. It does work, but there will still be some life in the rhizome that will come back the following year, but the growth will be very stunted. This growth could be reinjected or just sprayed. My uncle had it done at vast expense and it worked well.

Maybe so, it would be flexible by its nature. Still would stop the chain penetrating far though. It was Oldwoodcutter's "Close Call" thread that started me thinking. Remember that lad who was killed by his topper biting him in the neck? I don't know the details but if it were the back of the bar that hit him, maybe this invention might have saved him. Im thinking at some stage I will have to chuck down a spar, and the idea of gaffing out and slipping onto the back of the bar has me thinking. I realise guys do this every day and with proper technique there should not be any possibility of that happening, yet - people do have accidents.

JimThere may be a solution that allows a SRT acsess with the base anchor advantage while at the same time isolating the access line to the tree. Imagine, if you will, a coupling of the access and ancor rope under the branch or crotch. This coupling would grab tight on the anchor but slip on the acsess, allowing a small bit of slack in the anchor, thus putting all the weight on the access. If the anchor was cut it wouldn't affect the access. The problem would be how to remotely remove the coupling by the groundie - the solution would be a quick release device activated by a light throw line which could run parallel with the anchor line. How to build a quick release device I would leave to better mechanical mi ds than mine.
-
Ah yeah, thats probably where I got the idea. Feck, everything been invented already. I was thinking the target end user would be myself actually. Bit of a sissy, me.
-
Looks par for the course to my eyes. Back cut looks like its below the hinge - should be slightly above it, so I guess he got that wrong. No PPE obviously, but, like I said - par for the course, unfortunately. He should have roped it really.
-
That could be an issue...I imagine it being about an inch wide, and no thicker than the bar - maybe 2/3ds the thickness of the bar - so the chain width would be substantially thicker. Do you think there would be enough compression one inch back from the bar top to pinch? Oftentimes I buck halfway through a log under tension before it starts to pinch the bar. One would have to use it judiciously, more thinking of horizontal cuts on stems while gaffing, and I suppose a wedge would be required.
-
Yes thats true. I suppose it could have a quick release mech so you could attach it to the dogs/spikes without unbolting the spikes. Would only be used for situations where one really wanted to reduce risk at the expense of productivity.
-
Thinking about the hazard presented by the top side of the chain - no need to give examples. Wouldn't this effectively render the top side less dangerous in the event of an accidental contact? I was thinking about gaffing out on a pole while starting the cut, that kind of thing - not to be used all the time but in higher than normal risk situations. It would be an extension of the felling dogs, made of spring steel. The same width as the bar, and the two edges blunt or rounded to avoid snagging on wood fibres. Anyone know if this has been invented before?

FREE eBook on chainsaw maintenance

Hi there, I subscribed, got to the page with the books and the download button but when I clicked it didn't download - just a few pages in a new window. -
Definitely inertia. Happens often to my 201 c when de-branching tight trees, the break activates at the merest hint of a kickback. I make a point of blowing out the break works regularly, amazing how much crud builds up in there.

In several years of lurking on arb sites - and gleaning much valuable knowledge - that is the most brilliant thing I have read. That's what I'm going to do, and I hadn't thought of it. So glad I checked. The rescue thing is the one thing that stumped me while working as a groundie, in. Fact it just wasn't a possibility. Thanks man.

Wouldn't be that hard to build....a drill motor, low geared, and a small capstan...chuck a free fall arrest cam in there somewhere. I hear they've discovered a way to prolong the lifespan of lithium batteries - Whereas now they can be recharged a thousand times, soon it will be fifty or a hundred thousand - effectively a battery for life.

Its only a matter of time before the lithium-ion powered multicender is invented.
