    Reminds me of brave new world where foetus' brain development was curtailed to provide manual workers

    I think even 2 star had lead in it back before unleaded was available. I believe the lead also acted as a lubricant and two strokes benefited from that. By now I would have expected to see a study showing how much better kids were growing up without as much lead in the environment twenty years after leaded petrol was removed from sale.

    I've never driven slopes that steep apart from short steps with agri-based forwarders. I would consider it with a purpose built forwarder but not if I was depending on that cage for braking the rear bogie.

    Is unleaded avgas available in UK? I thought it was all 100+ octane and leaded here

    Sylvestris and nigra are the only common ones with 2 needles but some of the 3 needle pines can exhibit just 2 needles. Scots has the bluish needle and smaller cones.

    I thought scots pine

    At this rate he won't be climbing any trees, BTW my bete noir is ailanthus altisima for snapping unexpectedly

    I only thought copper sprays were to combat fungal infection and didn't realise any such products were still on the market.

    It's a shame our more erudite members haven't chipped in, I am no plant pathologist nor expert. If it is fireblight, and the fact the whole crown is not yet infected points to this rather than a root problem like honey fungus, then it is a bacterial infection, the lesions, (splits) that show in the stem point to this as the bacterial exudate pushes out through the bark. Also despite your view that strimming hasn't caused an entry wound that basal wound and swelling does look like damage done a few years ago and is the trees way of growing over the wound. On a you specimen like this standard advice is to start again with a less susceptible species. You could try to cut the dying bits back to sound wood i.e. to the point were the cambium is bright green all around the cut.

    That's not true about spiking every tree. The old school utility arbs are still out there, boshing off limbs at the stem without a care, but less so these days. Distributors now insist that work is carried out to a decent standard, you aren't allowed to spike retained trees, and works are to bs3998 where possible. Tree work is subject to checks and auditing. Distributors have got environmental policies with regards to tree and vegetation work, biosecurity and all that, and their arborists or subcontracting arborists will have to adhere to it. I'm glad to hear that, you must be a better than average UArb, my experience with rail and utilities arbs is that they attract the worst sort of tree hackers but I retired form this sort of work 4 years ago.

    not great pictures but it does look like fireblight and those vertical lesions on the stem also look like symptoms of bacterial infection. It often enters through strimmer damage at the base.

    When you check this you may find it is an easement rather than a wayleave and this will show on your deeds, easements are a bit more onerous for the landowner.

    Utility arb work is all dependant on the proximity distances between the tree and live wires and the qualifications of the people doing the work. Sometimes any work requires a shut down . There is provision in the legislation for a landowner to do the necessary work and charge for it but you would have to comply with all the safety requirements of the Distribution Network Operator, Electricity Northwest in this case. They will want to remove all branches from near to the live wire and a bit more to allow for "resilience" for the next five years.. You are better off asking that they do the work to British Standard for tree work 3998 as was and not allow the use of climbing irons if the tree is to be retained. Utility arbs have spikes permanently attached to their boots.

    I think I have seen this before, it's interesting how the chain is noticeably slower after only one tank of cutting and this shows @Stubby's point about sharpening after re fuelling. All the chains except Stihl's look like they would benefit from a light touch up before use. The thing is his using sand glued to the wood is too harsh and none of the chains are fit to use after, even cutting skidded timber one would be forced to stop and swap saws or resharpen. The video only shows one normal semichisel chain and while it shows it had a smaller percentage change when it was blunted it doesn't really show if there is an actual benefit from using semichisel under these conditions. It does show that using full chisel will be faster in general cutting.

    yea I often did the same as it gave me a breather too, similar with the fagging hook it was a break to stand upright and run the stone over the blade when weeding new planting.
  17. openspaceman
    I thought you had done production harvesting? One cannot stop the flow of a chap knocking over, knotting and topping 8 trees in about the same time the skidder driver can chain then up and drop them at the landing just because the chain is not razor sharp. It's not blunt but perhaps needs a bit of pressure to bite. The question I am asking has anyone demonstrated the difference in productivity when cutting direty timber starting with sharp saws of both types. I use saws much less now than I did 30 years ago when I was very sensitive to dull chains and dust affecting air filters but seriously blunt saws tend to wander off to one side or produce saw dust rather than flakes.

    Sell him the timber standing and charge a rent for the use of the barn and yard.

    Yes but a dull semichisel can keep cutting a bit longer whearas once the tip is gone off the full chisel that's game over. I cannot remember when I first came across full chisel but round chipper .404 was standard on the big old solid nose bars I first used. We went straight over to full chisel as soon as I became aware of it for the felling saws (though there was talk of semichisel being better for pruning). In those days we were ground skidding and the cross cut saw at the landing was an 80cc saw with semichisel 3.8" just because it would keep cutting dirty timber when 8 logs were dragged in to be processed before one could consider resharpening. Is there any evidence of the differences between sharp and dull chains of both sorts differing in performance?
  20. openspaceman
    Obviously play the trumpet too 🙂
  21. openspaceman
    I'm amazed no one has hacked it yet, what inputs does it use? Presumably the information stored is the saw's details and history and then carb settings at different rev ranges.

    Paul Elsey, he emigrated to America and died shortly after. He bummed a piece of ash from me to see how the mill cut. Last time we met was before Google and he was designing telephones I think and promoting a search engine agglomerating thing called secret squirrel. Very hard work running the trekkasaw and I had lots of trouble winding the handles in sync. It cut better than the Woodmiser. My mate never let me loose on the Lucas some 30 years after I had used the other mills and by then I was 65 and found assisting him a real struggle. A chap call Atkinson took trekkasaw over and his salesman , Richard Slatem, went on to found Fuelwood Marwick. I think Robin Carter of Milland Fine Timber next owned them and he sold the business loglogic.

    I think it could be Hawthorn Webber Moth although Antrim may be a little far north for it

    Okay but were you considering what happens when an articulated tractor pulling a trailer gets out of line, if the trailer overcomes the steering ram it forms a letter N
