    Yes if the wood is oven dry there is no moisture left in the sample. I had been experimenting with wood drying for over 25 years before I bought a meter and even now I would only use it to get a general indication and would revert to oven drying for a definitive answer. My moisture meter gives up at less than 10% and I'm not sure that it measures wwb or dwb. For us wood burners 25%dwb is 20%wwb so not a great difference as the figures get lower.

    Yes I would expect fresh felled willow to be up to 60% water and 40% dry matter, maybe a bit less moisture in winter, especially in the middle of a larger diameter stem. Given the OP's figures if in an unheated building it would tend toward 17% mc wwb but in a warm room about 10%. The way to check is heat it to 120C for 24 hours to get a oven dry weight. Then 757-468=299 299/757=0.3817=38% mc wwb But if it is still 10% then the oven dry weight is 468*.9=421.2 and the original water content is 335.8 so the original mc =335.8/757=.44=44%mc wwb which is equal to 335.8/421.2=79.7% mc dry weight basis which is how a joiner might look at it. In practice my wood dries way below 20% mc wwb in a summer so I seldom get the meter out

    It was the same with the phosphor bronze bushes on the swinging arm of old british bikes, the steel shaft wore, that I put down to grit getting embedded in the bronze and grinding the shaft, With a chainsaw small end the gudgeon pin shouldn't rotate in the piston, the movement should be in the small end bearing.

    I would love a battery saw for a bit of guerrila path maintenace but at a grand for a husky and with over a dozen 2t saws not worn out yet... Anyway to diverge a bit; to me he cut was always a plash cut and the whole job was plashing and pleaching. Never really having done any other than simple demonstrations I wonder what the etymology is, after all if you pleach trees you bend and twist branches together with no cutting.

    Hugo at Rowena motors is the bloke to speak to about the correct part, the search facility on their website is a bit arcane.

    Neare 50% is my guess from selling to one many years ago.

    I thought it was the other way round and they were being spiteful 😉

    Never having been on the dole and always self employed since 1974 I was under the impression you did get dole if you were sacked but not if you resigned? Having lived through nearly all of the "welfare state's" existence I still believe it was a wholly good thing born out of a period when the people of a united kingdom decided that co-operation had got them through desperate times. There was nothing unsustainable about it until the super rich were able to pull away from the middle and working classes and essentially avoid and evade personal income taxes. PS I think deportation to Rwanda was unacceptable but I agree the nations the immigrants passed through should have some of the responsibility for stopping them and pre processing their true status.

    This is the crux; most out of rotation coppice will not produce stems of a quality to produce decent rods useful for anything other than ethering for hedge laying. Often you need to coppice the lot and wait 7 years or more which can be a problem if deer pressure is high.

    Children would suck off the fleshy bit and spit out the seed for a bit of sweetness during sugar rationing, my mother called them snotty gogs

    Bark definitely has more ash from the minerals than actual wood, I wonder if it has a higher calorific value too.

    It's because the cutting actually flexes the disc toward the anvil and the further away from the centre you get the more flexing

    As an ex employer I would give anyone a try but even if they offered to work for free they would get the minimum wage even if I terminated the trial at the end of the first day.

    If you use a chain on the tree put it low, but not so low you can't snick some cuts with a saw from the left hand side in the unlikely even it does snag, with the hook at the bottom and chain doubled back to the left hand side to give it a bit of rotation as it moves.

    My guess would be japanese privet

    I'm not familiar with the workings of the timberwolf but is the engine reaching sufficient rpm? The feed rollers on other chippers with stress control will not feed unless the engine is running fast enough. Also some machines sense their speed from the alternator and if the belt is slipping it will not reach speed.

    Looks like the dark patches are from previous mechanical damage, the more serious problem is the narrow fork with bark inclusion which looks like it may be separating, if so one stem will likely fall some time but further inspection of this is necessary.

    I can't say for deer, I never saw a feral deer before I was 17 here or elsewhere, now I am more likely to see one than a rabbit since they were hit by mixie followed by hemorrhagic disease. Grey squirrel have a very catholic taste and will eat unripe hazel nuts before dormice can digest them. Here they also are supplemented by bird feeders in the winter. I did come across a dormouse in an ivy covered alder I felled two years ago and there were plenty of squirrels about.
  21. openspaceman
    not to mention grey squirrel out compete them for hazelnuts

    Sounds like a 3 or 4 position durite ignition switch which I think jcb used have a gander here Ignition Switches | Plant Switches | Plant Electrical | Plant Spares | L&S Engineers WWW.LSENGINEERS.CO.UK Plant Ignition Switches/Barrels for with & without keys. Lucas, Bosch. Key numbers including 14644, 14603, 14607, 35670...

    The legs, sides, door top baffle and top of mine are still okay, it is the back that is split if you want some green enameled bits.

    I thought the issue was that non car derived commercials and 4wd weighing greater than 2048kg empty were restricted to 60 on a dual carriageway and 50 on an unrestricted single carriageway. Not much chance of being caught but if you are and doing 70 on a dual you get fined and points for being 10+ over the limit. 70 on a single and it's 20mph over. n

    Most of the stoves I saw in the early days had no lining. I don't think I came across any before 1978 My 602 has a cast iron door with no glass, it has two cast iron side plates which hung from pegs which will have raised firebox temperature a bit. Later 602s had some glass in the door and then they revamped the air flow with heated secondary flow and firebrick lining.
