  1. I may be missing the reason behind the question because I have not followed the sub thread but in the case of life insurance, which is a bet by the insurer as to how long the wannabe insured might live, having medical information about a person that shows how that person differs from the norm may mean the insurer will not take the bet or change the odds, so the wannabe's estate would suffer financially or the premium more expensive. It's the opposite of what the NHS was founded for, which was to budget for the same bet and take the risk on behalf of the whole population. Public health statistics is all about economics and minimising costs, as was put to me by an economist in the health trade it's like pressure-volume theory in gases, we measure pressure which is the integration of the effects of billions of gas molecules bouncing against their containment so we can establish a trend, it says nothing about the speed or direction (velocity) of any individual molecule.
  2. I often wonder if the first people in England to smell coconut said if smelled like gorse bloom?
  3. So I'm a sinner and a cheapskate. Most of my working life I used a 60cc saw with an eighteen inch bar and I would choose a lightweight bar and the sprocket bar sprocket would be the first thing to fail. I still have many part worn chains kept "just in case" after I replaced a bar and put a new chain on for it.
  4. I would just use the rim at least until the chain is finished. Rim £8 probably last for 3 chains or more 25" chain £25 25" bar £65 should last for 10 chains in forestry probably a good deal less ringing up firewood. Production tree felling gets through comparatively more chains than arb work because felling close to the ground is affected by soil contamination of the bark, worse on sand and negligibly on clay.
  5. It was fine and reasonably priced but I haven't used it with the collector yet as I left the mower for use on glades in a community woodland.
  6. Yes but this never happens if you burn dry wood vigorously as the temperatures are above the dewpoint of the water vapour. As I have posted before I am not using a steel liner as I utilise the fact that the chimney breast brickwork absorbs heat whilst firing and then the thermal mass gradually gives out heat overnight when the fire is out.
  7. B C or D I wait until the drive link reaches the bottom of the slot or the rim explodes, whichever comes first but I'm a sinner.
  8. takes me back but to be consistent H(ypotenuse) squared = A(djacent) squared plus O(pposite) squared
  9. It looks like a cast in situ (high alumina?) concrete liner to me. The stove installer can pressure check it to see if it is still suitable and still sign off the installation.
  10. Thanks, I've possibly left it a bit late, will look into it a bit more but not too worried as I'll still have the trailer and bike categories which I will use.
  11. So it's a lesser medical than some, I'll look. Do you know how soon before one reaches 70 the medical can be?
  12. I wish Last one I had for PTS was over £100 and a 55mile drive, that was 7 years ago.
  13. Yes I think so if we are talking about a chimney with a flue up to 9". The building regulations only specify minimum sizes and not to discharge a lager outlet into a smaller flue. There is a stipulation that it can be unsafe to discharge into an oversized flue, so don't exhaust a pipe through a register plate and then direct into a chimney of an inglenook for instance
  14. These are also the ones I use in the winter, KF 120s if it's warm. I worry they don't protect against vibration as well as gel ones.
  15. Yes. spend a hundred quid for something I may never use and a 70 year old ticker may not pass anyway. It was bad enough spending £75 for a doctor I have never seen to tell the police I wasn't a depressive and no obvious reason I couldn't use a 24"+ steel tube.
  16. Is the ring common to any Husky models?
  17. Mine has the 107 note on the C1E because I never asked for it not to be put on as I was unaware of the requirement. Now I'm wondering if even the C1 is worth keeping as it will automatically expire this year. I haven't needed it since I retired and my days of driving horse boxes went when the girls gave up their ponies.
  18. best put it all in a box and keep it for me then.
  19. I'll pass on the suggestion but not seen it myself as he is a fir way from me.
  20. I've had a message exchange with the owner and on re testing the compression once the oil was blown off the bore it was dropping to less than 100psi so he took the cylinder off and the piston showed definite signs of blackening by blow by so he has concluded it was too worn to be worth bothering with. If it were a decent saw with a nikasil bore I would have popped a new ring in but a cheap blower...
  21. I liked the Kidd twin chop for just this sort of work, no need to set it low. Crude but robust. In this case as the rides have been mulched the drying then baling seems a better option. The failing with all the conservation harvesting I have seen is they just dump the arisings.
  22. Maybug (cockchafer) here this morning, also pair of brimstone and a holly blue in the garden but not seen much else recently.
  23. Grasses are competitive in high nutrient status soils and especially so when other plants are drought stressed. Removing a late hay crop takes off lots of surface minerals. Also overgrazing has this effect which is why horse pastures become dominated by buttercups. So removing a grass crop as hay after flowering plants have seeded is a way of encouraging the flowering plants that require less fertile soils to compete. Also in a woodland setting the deeper rooting trees and the mcorrhizas associated with them mobilise nutrients from the mineral soil and deposit them onto the surface as leaf fall, so carrying off minerals with a regular cropping cycle, like hazel coppice on clay soils, limits the build up of surface nutrients and flowering plants like bluebells and anenomes take advantage of the temporay lighter conditions and thrive. Clay soils hold on to nutrients well and have reserves which don't deplete much over time. On lighter soils, like the Bagshot sands here, the minerals, once mobilised get leached away following cultivation and over grazing and plants associated with acid heath become dominant for a while. Eventually if this false climax isn't maintained, by grazing, woody species creep in and reach down to deeper strata, gradually re fertilising the surface layers till secondary woodlands develops.
