  1. The problem with nuclear fission is the capital cost and the storing of waste, they are simply too expensive in the face of renewables becoming relatively cheaper.
  2. It worked okay, seemed a long time but may only have been the ten minutes. I'm left wondering how well I did though.
  3. I will give it a whirl then
  4. Star shake in oak seems more common on the poorer sandy soils, I was told it was an adaptation to drought. It doesn't seem to be present on young vigorous trees, even on our sandy heath. Beams from a shook oak were still accepted for groynes on the beaches south of here. Often when felling a tree with shake you get sprayed with a mixture of sawdust and tannin stained water that has collected in the shake.
  5. They used to call it resilience cutting, to allow for up to five year's growth. In this case I guess it will only give them two year's grace.
  6. It looks like it is grafted and the rootstock is sending up shoots. They will need to be removed but not until mid summer to lessen risk of silverleaf.
  7. Commercial EVs will have a gross weight allowance of 4.2 tonnes I suppose, same as the driving licence IIRC
  8. I would not be worried about a burst, more about getting pulled over.
  9. The diamonds on the face or the wheel won't get any use and those on the edge too much. When I was at work I used to ask the builders for their diamond discs because I found the faces had some use for standard teeth after the edges were no good for cutting bricks etc.
  10. Much the same as on my Jussi and I doubt most would want to run down the road with them, not least with a digger, but the tyres are marked not for highway use.
  11. One day in my case as no one else turned up. Interesting subject though, I still look out for pairs of lines on wooden poles to estimate the voltage. I never got any further as I got retired.
  12. The tits locally have forgotten how to peck through the foil. I suppose there are far less opportunities to learn now.
  13. That was my thought if it is steel or. if the clamping is tight enough, do away with the tightening system and tension it by hand, then clamp.
  14. I was referring to the circlips that have tangs on them, I dislike them because of the OP's sort of failure. I was musing about how orientation may affect how metal fatigue may cause the tang to break off in use. I don't have enough experience of stripping a lot of saws so I do not know if circlips with tangs are used on original builds. My limited experience with Stihl and Husky saws is the OEM circlips have no tangs, so I stick with them. Yes it is important that the circlip has expanded into the groove firmly. I have yet to see the tool for inserting circlips without tangs that @adw uses but plainly the ones with tangs can be abused and bent getting them out and in with a pair of pliers.
  15. I wonder if the orientation of the tang makes a difference, my thought is if it is vertical it suffers a bit less bending stress than horizontal so could fatigue would be less.
  16. The base of the tree doesn't seem to get damaged by fire unless the fire actually burns it. Most of the damage is done when radiant heat breaks down the proteins in the cambium and the characteristic pattern of necrosis tends to look like an assegai spear blade, broadly curved at the base and tapering out at the top
  17. Strange, the few stihl saws I took apart the gudgeon pin circlips had no tangs.
  18. I don't know, just pointing out they can. I don't believe the pollution from a modern wood stove is as bad as they say either.
  19. Yes I don't think they differentiate particulates from different types of carbonaceous fuels but they do tell the difference from particulates from brake and tyre abrasion because of their chemistry.
  20. Particulates from combustion have a different chemical signature from other particulates.
  21. Most EVs do not pay any fuel tax (other than the 5% VAT on domestic electricity) as they charge from home. So increasing fuel duty just increases costs for older cars that then get scrapped early (don't get me into what silly faults make a car uneconomic to repair). With 2% penetration of EVs into the pool of cars it won't be long before they devise a road usage tax.
  22. It depends on the provenance (genotype) and perceived wisdom is that it needs to be done when the stem is less than 35 years old.
  23. It may help if people know the rough location.
  24. One is a criminal offence the other a civil one.
