  1. Air spade and cyclone over bulk bags? Would work out quite expensive compares with a pitch fork and shovel.
  2. Actually I think you miss my point, though no matter it was only idle musings. Plenty of rich people have private jets, yachts etc. as a result of having successful companies as well as riches gotten by nefarious means. These people will likely pollute more but don't have the clout to skew whole economies like the likes of the super rich with 10s of billions of $.
  3. Because governments won't spend the money wisely?
  4. Yes a split charge relay will only cost about 15 quid and that will isolate it when the vehicle ignition is off.
  5. Is it impractical to make some extensions for the lower link arms? A picture may help
  6. That's wealthy but by no means super rich. We need wealthy people to occupy the posh homes, else they end up preserved in aspic by the NT and no use for much, and buy the new cars which then become second-hand and affordable usw. The super rich have billions and often don't benefit an economy because it goes offshore. Also they can avoid tax to some, often large, extent. Our current system is based on the idea everyone can make their own decisions on how to spend and make money. Government takes a massive amount from every person earning money, in income tax ( which major contribution comes from those on PAYE and earning over £40k/annum), VAT, rates, car tax etc, and this gets spent on running the counry and making politicians above averagely wealthy but the money they spend is largely recirculated within the economy. We have a limited say in how we allow government to spend money. IMO we should be looking after the environment and the super rich have a few negative effects here, they tend to have multiple homes and travel extensively between them by plane plus they have ideas that do not fit in with looking after the planet, like in Bezo's case wanting to colonise Mars, this of course diverts vast sums of money that could otherwise look after the ecosytem we have. We have no say in this. It's not that I think the government should have extra money from the super rich more that the peaks should be levelled a bit, I have no idea how to address this.
  7. I agree and always managed on 8ply xply as the 14ply nokian were too expensive for my limited use.
  8. Probably nothing to do with it being softwood more to do with a smoudering fire of damp wood dumping pyroligneous acid up the cold chimney such that it condensed. SS depends on a thin film of chromium oxide forming to resist air getting to the iron and rusting it. Chromium oxide reacts with acid, exposing fresh chromium and iron to oxidation. Long ago I posted a picture of a 316 ss rigid single skinned flue perforated like a colander, the fix was actually to insulate it to keep the flue gases above their dew point. page 7
  9. I don't know if anything has changed but traditionally it was their retirement.
  10. So am I but I cannot update mine, but I also run Chrome to view these, 'cept this one was on its side
  11. Even if it is just off the trailer they will make more noise and take longer if it is off. Those RDS units can be configured to need a pin code to start too and if the engine is not running and they cannot pick it up then it is difficult to move. We had 3 stolen in 7 years, two on trailers and one that was started with a generic key. The adjacent house owner in the last case heard and saw the grinder cutting the chain and did nothing.
  12. I suspect you need to update your browser, it didn't work on mine either
  13. Sorry for your loss but the number of times I tell people never to leave tracked chippers on trailers...
  14. That doesn't actually answer my question until you dry the sample in an oven and calculate the moisture content. Please try adding some salt to the water before you test it again. Logs coming in from my store seem to be at 16% and I suspect most moisture meters would give a reading of 20%
  15. Why? Have you put a camera down the drain to see if it is vulnerable? Is the tree causing other damage? Most ornamental cherries don't get very large so why not enjoy it for a while more?
  16. Has anyone found a meter that reads moisture percentage on a wet basis yet?
  17. To my mind softwood over 200mm was worth selling as bars and sawlog. Many years ago I saw the Bilke wood processor with a shear cutter and splitting action processing wood fast but rejected it for my commercial use because the logs weren't likely to please my customers on aesthetic grounds. In your case you just need too cut and split to suit your boiler and for seasoning. It will manage up to 250mm. A cone splitter could half the bigger ones as it will take 340mm slabs. I have no idea what they cost. When I saw this earlier version demonstrated it was running much slower than the modern videos I see, slow enough for the lengths being handled in to the cutter to be rotated 90 degrees between cuts which enabled the splitter to split the pieces twice as the split propagated up the log. The modern version is slightly different as the splitter no longer leads the cutter. You could quickly build a square store with your 4m lengths built into a box with alternate layers on each edge, fill that and cover it with a tarpaulin.
  18. Yes but you would still need to be registered in HETAS's woodsure scheme to avoid a summary fine if caught. The only get out seems to be to supply 2M3 of 20%mc wood with the warning words that it might not be seasoned as that would be within the payload of a 3500kg MAM vehicle. The use of the word "supply" in the regulations is interesting because it might mean someone giving me wood for burning in a domestic fire may be in breach of them.
  19. Strikes me it's remarkably similar apart from a safety aspect,
  20. I'm surprised it's a bush and not a needle roller bearing. I cannot think of a two stroke I have taken apart with a bush. Anyway if you buy a bush and press it in you would normally need to ream it to fit the gudgeon pin.
  21. I was trying to point out that if any meter gives a consistent result it is still usable even if the result is wrong because a correction can be applied, whereas if it gives results with a wide scatter even if they are centred on a single result it is worthless. Not having used one I am still in the dark. Take target shooting, if you strike the target in the same place and every time it hits the same spot within a couple of inches but several inches from the bull it is precise and you need to offset your point of aim from the bull to be able to consistently hit it. If the shots scatter randomly around the bull by a couple of feet then it is accurate but imprecise and not usable.
  22. That's a posh meter then? I've been using my multimeter and it's giving readings in the 15-30 MOhm range with the pins about 10mm apart on dry wood and about 6MOhm on fresh. I dry smaller samples in the microwave but back in the day I would leave a whole log in the fan oven at 125C, I would log the electricity use and this gave a direct relationship of the constant heat loss from the oven plus a close match of 0.7kWh per kg of water lost
  23. You need to define accuracy. If the log has been drying the reason you split it is so the meter measures the wettest (worst case). Not having a meter I cannot experiment but I imagine one could get a feel for the average moisture content by comparing an outside reading as well? If readings taken by the meter are consistent and the logs are then oven dried one could decide with what precision the meter measures. For most cases we are discussing here we just want to assure ourselves and customers that the product is less than 20% mc wwb so a reading of 25% mc dwb is good enough for that. Anyway if the reading is marginally close just keeping a sample log in a normal room will increase its chance of passing the grade for a few hours till a second test 😉 I've no way of telling but it's easy enough to check as @Woodworks did recently. It only takes minutes with a microwave but get it wrong and your readymeal has a wood-fired flavour till you buy a new cooker. This article implies that his meter also uses a generic chip that measures the resistance of the log and has a look up table that compares the resistance with known moisture contents and displays a dwb reading. There are other ways, like dielectric that can be used. These chips were developed by companies selling snake oil damp proofing products to otherwise intelligent but gullible home owners. They were so successful that home insurers fell for them hook line and sinker and old houses which had been inhabited for centuries became difficult to insure unless work was done The moisture in a log (sap) has various dissolved salts in it, pure water is a good electrical insulator but the salts plus water make an electrolyte, which conducts electricity. I don't know how the resistance of this electrolyte varies as the concentration changes as the water is lost but imagine it gets higher resistance as it dries. As the pins are a fixed distance apart this removes one variable. So with lots of measurements one can see a correlation with resistance and dryness. This can then build a table by comparing resistances of logs that are then dried in an oven and comparing this oven dry weight with its original weight, the difference being the water.
