    Have you considered using the thermal mass of all the masonry to complement the heating?

    Ist picture is exhaust side, then two of inlet. It looks like something has been ingested from the carb and dinged the piston skirt. A modern stratified intake saw and little wear showing. Have you checked the ring gap?

    Yes beech is about the heaviest but I was trying to work backwards from the 10p/kWh figure. 350kg to the bulk cubic metre at 20% drops the price to just over 7p per kWh. @Squaredy I was pointing out the unit of energy is kWh the W is capitalised as it is named after Watt. Whereas we don't capitalise wattage ? and the h is for using the power for an hour.

    Too simple as your units are wrong but I agree with the gist of what you meant to say 1bulk cubic metre of wood seasoned to 20% weighing about 250kg?? contains 1000kWh and costs £100 It also burns less efficiently than the others so more heat is lost

    I leapt to the conclusion he thought a previous structure had burned down!

    I have one 4kW stove which is lit much of the time, though it has not been on these last two days as weather mild, and it heats my two small living rooms. The gas central heating only comes on twice a day if the temperature falls below about 15C. The wood burner keeps the solid wall house at about 18-20C most of the time. So far I have used up my log store whose internal dimensions give 3.8m3. So about 2.7m3 of solid wood at 20% mc. Given we are only half way through the winter, albeit a very mild one, I'll have to double the size for next year.

    One can still find PDF copies of the original EA position statement found in the is old post: However they are not dated and the latest position statement (which covers treated wood as well, when intended for incineration at a licensed premises) expires in June 2020. So the salient point is that virgin wood is not waste, even if you are registered as a waste carrier and are transporting it, so no chain of custody is required. Of course if you are carrying waste then you must have transfer notes but there are allowances for when you take the material to one place wherein you can make an annual statement.

    I read a bit of the article but as with much of this disease and pollution business they are confusing the cause with the result. The number of people dying from lung disorders is being directly attributed to pm2.5 concentration in the local atmosphere. It says nothing about exposure of the individual over their life or the lessening of their remaining life. Yes most particulates are man made and yes particulates do cause lung problems but it's not likely to be a direct correlation and the exposure now is less than the exposure many of we older folk will have lived through.

    It's a piece of downland rather than a woodland where I shall be felling field edge ash next week. It was split into 20th of an acre plots and sold off, even to some chinese investors. The council have successfully stopped all development and the chap I work for has purchased all the accesses. He has granted the general public a permissive use, which in practice opens the whole field up. A good result all round as he has cut the scrub and returned it to a chalk downland again.

    It's a single piece rather than taperloc. I would have expected to find a grub screw on one of the shoulders but otherwise I'm not familiar with this, sorry.
  11. openspaceman
    Ordinary taperlocs have two blind holes with a half thread into which a bolt can be screwed to drive the pulley off the taper. A picture would be handy @tim361

    One can plug in figures that suit one's particular circumstance, I was trying to indicate one way of judging how much capex was justified for the OP. I do it from habit and because often (more so in the past) what I burned would otherwise have rotted in some field.

    Bicycles have been allowed to use bridleways since 1947 IIRC before that the only difference from a footpath appears to be that you could lead a horse along it by the bridle. The 1968 act says that cyclists must give way to walkers and horseriders but also places no obligation for the way to be fit for cycling. Interestingly while you may push a pram on a footpath you have no right to push a barrow/cart or bicycle on it.

    What would worry me is that it wouldn't increase the resale value of the house, so great if you stay in the house for 30 years but... I invested £300 in a stove and £1000 having two chimneys relined 35 years ago, I replaced the stove for £1000 over a year ago. It would be interesting to have a stab at how much fossil fuel I have avoided over the time. Say the stove runs 200 days a season and it is kept stoked for 12 hours and outputting 4kW. At today’s gas prices that's a maximum saving of £384 per year.

    Any particular reason for going for Eder over the PCW? It's the rope activated throttle that I like the look of.

    Not a small car though. Diesel ones seem to be a drug on the market atm. I wonder what newer Vitaras are like, my 20 year old one is fine for me and the dog but otherwise a bit cramped and it is underpowered and barely manages 30mpg.

    Farmers can plough a field with a PRoW over it but should reinstate it withing 14 days That's not the same as damaging a highway making it unusable. For that you need a Traffic Regulation Order and the cost of making good will be...

    Treadlight sell a forestry kit of strops and pulley. There's no way I'd use a tirfor if a powered capstan like this were available, I might be able to keep going at 100W output on a tirfor but petrol power will do 20 times more and no tiring out all in a package much the same weight as a tirfor, similar cost magnitude too. I'm vacillating over buying one of treadlight's offerings and a basic ground anchor for felling a load of small ash into a field which they lean away from.

    Yes the nikasil bore is very hard and aluminium pick up can look like bad scores but will etch off with chemical then a meteor piston and rings can be a cheap fix. That said if the saw has had a hard life I would wonder about the state of the bearings and crank seals before fitting expensive parts.

    I wouldn't be surprised if the cost of twin wall flue to over the eaves plus all the brackets and fixings would exceed £1200 before you factor in the labour of cutting the hole through the cavity wall and fitting.

    Angle driver and cold chisel is faster but I used to carry these above and an old fashioned 1/2" impact driver and two lump hammers plus 4 replacement shear nuts to put it all back together. It's surprising how tapping the dome nut will often allow you to undo the shear nut by hand.

    I had a SWT pass for work in 2011 my colleagues were jealous but I only used it for about 4 days and that was only to access south london stations and my annual medical. Driving the van made better use of my time.

    I used to get through lots of 7mm skidding chains. For a while I found a firm in Birmingham that would sell me "brothers" that one leg had failed LOLER test, they would sell the remaining legs cheap and I bought new Kuplex logging hooks.

    There's a code of practice, essentially the restraining sytem has to be capable of resisting the mass from moving forward with a force equal to its weight, sideways or rearward with half that force. https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/411093/safetyloadsonvehicles.pdf

    I'd say it is because the firebox temperatures of a modern stove with insulated sides and back are much higher than a traditional cast iron box. The baffle has the firebox temperature underneath and the not much lower flue temperature on top. Vermiculite is probably good to above 1200C, steel about 700C and I'm not sure about cast iron but probably not much more than steel. What I wonder is why there is not more heat exchange surface above the baffle.
