  1. The lesson these pictures teach me is never trust what you see in a digital photo
  2. You may do it at any time as long as you are not disturbing nesting birds. The chances of a nest in a cherry tree are low but an inspection will ascertain that. Hedges tend to be a bit more of a problem to investigate.
  3. I don't know what EA lidar data is available now but over ten years ago I downloaded some to look at the old workings and three barrows on the local heath. It seemed to be aimed at determining local flood risk. At the time, on my non cutting edge Pentium PC it took ages to render an image. The data had already been processed to show the longest reflection,so tops of trees were filtered out, and only the ground surface was shown.
  4. Galvanising is a sacrificial thin coat of zinc stuck on the iron and it corrodes preferentially, so it gradually gets thinner but because of the electrolytic effect it protects the iron from rusting, once the zinc corrodes away the remaining iron starts rusting. Once it gets to that stage paint is a protection for the sheet.
  5. Sounds like the carburetor float isn't floating
  6. Gluten hold the CO2 bubbles in.
  7. Any amount of rye seems to stop the bread from rising. I still have a few kilos to grind from a bucketful a farmer gave me but the wife doesn't like to use it.
  8. I think @bmp01 took one apart and repaired it.
  9. branches ring barked by grey squrrel? I'm seeing a lot of it this year, damage happens in July but withering becomes conspicuous as the leave go brown now. Interestingly the young 6m tall ash I have grown from seed, as a dieback experiment (I prune out affected branches as soon as I see them), showed some symptoms of ring barked branches. Closer inspection showed it started at crotches, just as with squirrel, but I have seen no squirrel and the gnaw marks were too small. It was a bit of a mystery until I noticed a few hornets visiting yesterday and stripping, presumably for the sap.
  10. I hope they remember what happened to French and German armies that over extended themselves into Russia.
  11. Good story @Billhook However it doesn't look like @Lorraine Higgs has been back so far this month, we do know she has some mature chestnut of coppice origin in Kent.
  12. I had their hydratongs on the back of a Holder A55, still have the Holder but when I last went to look for the tongs they had disappeared.
  13. two separate oaks about half km apart, one 30cm limb each
  14. I hadn't noticed the phenomenon this summer until today walking along a towpath where there was evidence of a couple of large oak limbs having fallen in full leaf, Obviously the leaves add weight, and hence leverage, but I wonder if the lignin becoming more plastic in the heat exacerbates the strain.
  15. We'll be finding out sooner than most and only we could get a surprise, I've been wrong before.
  16. That's right for most lithium nickel manganese cobalt ones used in power tools, these are the ones that catch fire if you abuse them but still have the best energy to weight. With seasonal use tools it's necessary to store them charged and recharge them after 6 months else the cells get low and the charger will not recharge them. I had a hedge cutter come in to the repair cafe that was flat and would not accept a charge from its charger. I managed to charge each of the 10 cells individually to 4.16V and it worked again plus could be recharged, which was lucky as the battery is now obsolete (same make as Titan).
  17. kaowool or cerablanket, it can be fixed on with a proprietary waterglass based glue but Holts gungum exhaust paste is similar. I think I may still have a part roll of it.
  18. Fenn mark 4
  19. Similar here and I only have the shredder guard on the 50CC brushcutter. I mostly use the two prong shredderon an old fs360 with the grass guard. I do always use the cup under the blade, it saves a lot of wear. It must be four years since I did any serious work with it
  20. I would always fasten a helmet chinstrap when riding but never had one on my hat for forestry or arb, I have had my helmet knocked off but always after it has done its job.
  21. 1024kg
  22. I realised this but if it would dry in any case how can you tell if the lunies have a point?
  23. Way to go Eggs👏
  24. Polytunnel mid summer easily dries cut and split firewood in a month mid summer in SE England
