    Because you need a flame to burn wood cleanly. If it's smouldering much of the chemical energy is going up the flue unburnt and ends up as tars elsewhere. It's fine if you burn a load of wood quickly and cleanly and leave a bed of char to tick over as that will keep alight with minimal air and only produce carbon monoxide and carbon dioxide.

    I doubt it but probably only around 2% of the log is lost as sawdust, far more lost in splitniks and bark falling off As I see it the major savings are in cutting rehandling and loading compared with a chainsaw and axe, plus the machine doesn't get tired. Handy for heating the drying floor if stocks get low in the winter

    I am not a planning expert but in general it will be B8 Storage and distribution. There are many reasons why the planners will fight an application.

    Yes, don't attempt to keep a woodfired range going overnight if it means the logs smoulder, a flame always needs to be present unless burning out char.

    It's a change of use and subject to a planning application. How long do you intend to make use of the land in this way? At my last work the local council eventually complained and asked for planning permission but so far 8 years and counting (to 10)...

    I'm not keen on strimmers because they leave abraded bits of plastic and also the damage people do to stems with them. I don't consider the waste to be on the same scale as fibres from washing machines. The above link is a bit ambiguous, it says the line will biodegrade and rot away, all good if it rots to CO2 and water but most biodegradable plastics just de-polymerise to some extent, the smaller pieces then retain their chemical structure. Having been caught out with adding tea bags to the compost bin I'd like a bit more information but would use a compostable line (even though its shelf life would be short).

    More likely something has been ingested and bouncedaround the exhaust port a few times before exiting.

    Jules @JonnyRFT posted two pictures on different posts in this thread, the first was almost certainly S aria lutescens the second picture was a white poplar leaf as commented by @janey

    I'm not familiar with this saw but from your description it's a stratified charge engine. The bottom bore carries a fuel air mix into the crankcase and the top one allows just air into fill the transfer ports as the piston reaches the top of its stroke. Then during the power stroke the transfer port first purges the combustion chamber with the air , to sweep out the combustion products, before the fuel air mix enters. This reduces pollution and fuel consumption by not venting unburnt fuel directly from the transfer port to the exhaust.

    I've no idea what the flies are but the 5th picture looks like an ichneuman wasp and it is presumably parasitising the beetle eggs that are hatching and boring the holes and frass in your later pictures.

    Me too

    That's a nice oak butt in the last picture

    Are you sure it has any? I thought they were 2.5 common rail after 2002 so wouldn't necessarily have glow plugs

    I've just been splitting some beech logs and both my axes heads are loose ,they are several years old so the wood is shrinking in this hot dry weather.

    We were still using belex on an immediate use licence as late as 1990, the customer would not allow stump grinding for fear of spread of honey fungus, so a lifting and splitting charge was used by a chap who had been in the RE. He was a bit gung ho and at the end of play when he had some left over heused it all up on the last stump, big mustake.My only other experience was in about 1974 when a chap with a bit more of as scientific approach was used to splite stumps that had been excavated by one of those new fangled Hymac 360 tracked excavators. On that occassion I was impressed how the dirt was knocked off and the split bits could easily be burnt.

    Which is about 6% so about half what I would expect from green to 10%mc wwb All woods are different and I chose about middle of the range, I suspect oak would be worse than beech for instance

    That web page has a strange way of presenting it to my eyes. Yes I agree if is not very significant but it should be noticeable. If you take a hypothetical lump of wood and split it up so it exactly fits in a 1m by 1m by 1m box and dry it from green to 10% (easily attainable in this weather) you might see a reduction of 0.1% in the lengths, 4% in the radial dimension and 7.5% in the tangential, multiply them all up and it would be about 12% volumetric shrinkage. What I should have added is that as the cross section of the box hasn't changed all this will be exhibited by a loss of height of the load.

    He'd certainly have established a good habitat if they are nesting in his tubes, I thought they needed a close coppice canopy as they mainly stay off the ground.

    If it grips well initially it's either the ram seal is leaking or the spool in the control worn. Most likely the ram seal. An easy check, once the log is gripped, is to take the hose off the opposite (piston) side of the ram and then operate the control to grip it more, if oil comes out of the piston side the seal has gone. If the spool Once the spool is in neutral the oil is locked in the ram circuit and the pump is doing no work, so if the grab relaxes without the lever being touched it cannot be a pump problem. If the engine needs to be revved hard to get it to grip with the spool open then it may well be a low pressure from a weak pump, especially if it relaxes when the spool is open and the revs drop.

    I mention this because back in the days of the FMD outbreak the official line didn't sit right to me, so I mapped all outbreak reports on a daily basis and "aged" each point. A lady dairy farmer converted all the images into an animated .gif which indicated the paths of spread quite well when compared with the later official version. What became apparent was that most of the outbreak around Penrith was inevitable once the pig farmer failed to notify his animals were ill but satellite outbreaks in Wales and Devon resulted from a haulier continuing to , legally, transport sheep in the 48 hr period between notification of a transport ban and it coming into force. Mine is only an academic interest but before I was put out to grass I took charge of OPM residues from the railway and conveyed the sealed containers to a permitted incineration facility. I'm told now the specialist firms doing the same are charging several times more for this part of the disposal.

    I suspect you miss my point; many gangs commute into London and come home with waste. The outbreaks near my village could have come here in waste as they are 15 miles from the core area

    Thanks kRiSS My worry would be that the logs contained eggs and the crew had not noticed signs.

    What's the current rule on transporting oak logs and chip out of the infected area?
  25. openspaceman
    probably one of the voles
