  1. Interesting and unenviable situation. Bearing in mind that I am not a lawyer; trespassing onto the tree and doing the work would be a civil offence. The only remedy to the owner would be an injunction, which they couldn't get in time, and thence an action for damages. Given the approval for the work by the LA and as long as the rest of the tree was not damaged...
  2. Wee'd! The silly things you remember but forget important stuff flubbadub
  3. Curious! I would expect the biggest diameter bit to be the last to lower and first to push out as the pressure on that section is the lowest from the imposed weight. My trolley jack has some sort of two stage pressure release, the first turn lowers the load but then it needs another turn for the jack to retract fully, I just wonder if there is something similar happening here that is causing a small residual pressure to stay in the ram. Yes don't create a situation you cannot get out of, as HTB says try the other end if there are no obvious valves in between.
  4. Yes but have something to catch the oil. There may be a hydraulic "fuse" attached to the cylinder, this is there to prevent the body descending too fast. Once they have acted they lock the oil in the cylinder until they are reset by pressurising the ram again. I have never had this problem, or indeed had one in any of my tippers, the way around it will be once it has stuck raise the body an inch on or two and then lower again.
  5. Does it go down under its own weight if you slack off the hydraulic union to let oil out? If not then it probably is a ram problem.
  6. Makes good sense with those cheap plastic pipes as if one is split the guys will just keep pushing grease out the split and the bearing runs dry.
  7. If you PM an email address I'll send the full size image and will photograph the other 14 pages over the next few days. If you have any specific questions I'll wrack my brain and try and remember. Off the top of my head the brake tension screws only work one way up but can be fitted either way and you need a very thin open ended spanner to adjust the bite of the clutch handle.
  8. I haven't managed to start it yet , battery only just managed to turn it over and I haven't got around to trying again but I might ask you for some pointers if I have another bash. I have a generic VW biased OBD2 reader.
  9. That's the same engine as the one I have been offered, I'm just worried about the cost of getting it repaired, I had 3 with rover V8s and no problems.
  10. Which V8? I've been offered one with the BMW engine which is playing up and am undecided. The Rover V8 with twin Strombergs was simple and I managed about 19mpg.
  11. Yes it looks like there's quite a lot of unsustainable harvesting going on in many places worldwide, often to fuel our wish to reduce our carbon emissions. Mind we too have not restocked upland areas where the enthusiasm for the grant funded expansion of forest cover seems to have been misplaced. GDH did a good job. I also wonder if there are really three distinct types of wood burning? The biggest will be the industrial biomass burners, often subsidised by RHI and feed in tariffs, these will depend on imports and big forestry as everything has to be done in bulk. On the home front their raw material has displaced those former markets, sawmills, pulp mills etc. that were no longer competitive after GATT. Until very recently I think most landowners suffered a financial loss because of this as I saw lots of timber which would formerly have fetched a premium, as sawlogs, being chipped. Now the demand for biomass seems to have increased the price people are willing to pay. Simultaneously in real terms harvesting costs have gone down. It was always the adage that "forestry counts in large amounts" and mechanisation reinforces that. It does seem to be at the expense of ground damage. This leaves a lot of woodland uneconomic to manage, as GDH said, one of the effects is that organisations that own these " uneconomic" woodlands then, through ideology and ignorance, surrender any thought of emulating the practices that conserved these woodlands over the centuries, and thus risk destroying the things they expect from woodlands, like bluebells, anemones, dormice etc. The second group are this "luxury" market but their suppliers also require the same sort of wood that the industrial users want; something that can be easily handled transported and processed. Then we have people like me, "goblins" who have traditionally fetched and comminuted their own wood and will not pay the price demanded for easily handled lengths but will chop their way into arb waste which is uneconomic for lots of firewood merchants to tackle, though I foresee a lot of the firewood suppliers turning more toward this as a resource as industrial wood prices go up.
  12. I brought a small 750 gram piece inside to test it, it had been in length on my lawn since about August as I had no covered space for it. Though dry when I fetched it home it had reabsorbed as much water as a freshly felled piece. In the warmth of my study it rapidly went down to 30% as it' averages out at 21C and 33% RH here. It shows how with a good dry airflow will rapidly remove moisture. I then dried it in the microwave on the1st December and you will see how it reabsorbed 6 grams of water from the household air over night.
  13. I disagree, we have had punishment ever since society began. What's needed is deterrence and that can be making theft difficult and making it less worthwhile by depressing the value of stolen goods.
  14. Steve Bullman had Arbsafe on which all stuff could be registered and police had access to it, as do you or I for stuff marked stolen. It depends on there being a large number of users and reports to be effective and I get the impression uptake was low. It isn't visible here now so probably not being promoted but still at https://www.arbsafe.co.uk/ It also needs for dealers and people buying second-hand kit to interrogate it. The datatag database seems to be less accessible http://www.datatag.co/paniu_website/ and has an annual charge whereas Arbsafe is free for the time being but that cannot last as everything costs.
  15. Yes logically that's how I feel. I cannot see it happening in my area as local arboricultural contractors concentrate on core business, so it's not at all unusual to see logs left at roadside for collection. see Bob's log goblin thread and I've just walked half a tonne of oak branch wood into my garden that was left from a height lifting on the road outside. Also after 40 years of chopping logs and tending stoves it's visceral, if even a bit masochistic. The chap I occasionally work for has a field full of randomly dumped logs but unfortunately that's 40 miles away but I have managed to get some from Jonny Burch as I re organise myself.
  16. Sugar free banana oatcakes today, it works well.
  17. In June 2014 Stihl sponsored a scheme whereby attendees at a local event of the small woods group could have their saws registered with Datatag and microdots applied to the machines, many of the machines also had a chip (like those implants for dogs) glued into an internal part. I never did have any feedback as to what it would cost other than at the event. I have my saws on the arbsafe site also. Of course modern autotune engines have a chip with pertinent data built in
  18. I cannot help with that but I tried to explain how the vapours of the alkali metal species given off in a hot fire actually lower the glass fusion temperature when they condense on the glass surface. I used to know a naval engineer who operated a "ship's" boiler to burn straw for power generation. Straw has a higher mineral content than wood and he could see the vapours condensing on the superheater tube and dripping off as molten slag. Most of the ash will be from bark.
  19. Firewood conversion is labour intensive, Latvia monthly wage is about £500 which is a quarter of what you would need to pay here.
  20. I think the pre heated air jets that comes from those holes is additional secondary air just to ensure a complete secondary burn. With a modern wood, not multifuel, stove it seems that all the air is "over" air, the main air, including the air wash down the glass, acts as both primary and secondary air. My multifule stove has a provision for primary air under the grate but it is not used when burning wood as 70% of a wood fire is volatiles burning, whereas a coal fire is 90% fixed carbon burning. A traditional up draught coal burning fire requires the primary air under the hot coal, to gasify the solid carbon to a mix of carbon monoxide and carbon dioxide, the CO then burns out in a secondary flame. Oddly I do have a slight hazing of the glass if I burn vigorously for a long time, it wipes off next morning with a damp tissue. I take it this is fly ash wafted of the surface of logs with pyrolysis offgas. It shows that not all particulates from a stove are black carbon but also this fly ash, which I take to be things like calcium, potassium and carbonates and oxides of these metals with oxides of phosphorus, I can see if left on the glass with a very hot burn they could form a eutectic mixture with the silicon dioxide or boron silicates of the glass and melt into the glass. My previous stove did not have any glass and until now I had not appreciated how much radiant heat was given off through the glass.
  21. I can't see why. A room sealed system should be safer and probably the best in a modern airtight house but in a draughty house the small amount of additional air needed to run the stove is a fraction of normal air changes. As the clean burn stoves have some fixed secondary air they are impossible to turn right down and this is to prevent smouldering. Because of their action it is possible to extend the burn somewhat by using smaller pieces of wood during the evening and, because of the nature in which dry wood burns, a good depth of char will build up. This can then burn out overnight with the main air closed off and only the fixed portion of secondary air from above to burn the coals out. This will mean an increased level of CO in the flue gas but this will go up the chimney and is not a greenhouse gas. As I said in a previous post I depend on the masonry of the chimney breast to keep the house warm until I rekindle the fire.
  22. Yes but all three (two varieties of nigra so maybe 4) are two needle pines. The orange upper bark would show up as a scots but the pinaster is rarer and has bigger needles. My seed came from the progeny of the first generation at Kew. I felled the daughter tree in about 1986 and grew several seedlings, two of which I took to Devon along with 3 English walnuts the squirrels had planted in a friend's garden. The pinaster is the tallest tree for miles around in an exposed wet, windy spot 200 metres up on the edge of Exmoor, totally different from its Mediterranean home.
  23. Yes I saw that the first time and wondered because I thought Austrian or Corsican. Today I stood under a pinaster I planted at my brother's 25 years ago and thought the green was a bit brighter there.
