  1. My younger daughter's funeral and close family will have a cup of tea and scones in the garden after. We will have a proper gathering at a later date.
  2. I recently got a bag of dried food for the dog so no problem there for a few weeks. I was unable to buy bread and eggs in the village, don't need much else. We have a family do which cannot be postponed but my wife was able to get some basics from the local garden centre café as they destock, mostly by doing take away till Monday. As it's reported that 25% of our food comes from takeaways, cafes, pubs etc it would seem sensible for them to maintain their supply chains and do some retail to take the pressure off elsewhere.
  3. Nor I, they used the cylinder over pressure from a port where the decompressor is on many saws now, @adw is the expert on them
  4. I agree with @Rich Rule now as the clumps of needles show up when zoomed in, shape is right and so is upper bark colour
  5. IF the OP hadn't said it was a photo I would have said it was a painting

  7. not forgetting the arbrex 40 years ago Santar, a mercury based paint, was used for treating beech bark lesions
  8. Yes what happens is the piece the grinding wheel touches gets heated to red heat but then the steel in the rest of the tooth rapidly quenches it so it chills quickly and the crystals thus formed are harder. You can see this on the modern cheap (but good) hand saws where just the teeth look blue, they have been quickly passed through and induction process that has heated the sawtooth tip and then the surrounding air and steel behind the tip have rapidly cooled it again, hence the line of blue teeth.
  9. Good for her it's best for the nipper and a safeguard for her.
  10. Same here, plenty of vegetables but all white bread gone, wholemeal a few loaves.
  11. Just don't frap off any of the basal bark at the same time
  12. I would agree that extreme wealth is one of our societies problems but would love to see how it could be addressed. Governments have been slow to react to predatory american based companies like microsoft and amazon filching untaxable income because we have been sold the idea of free trade by America, the African countries are being devastated by the american controlled IMF forcing them to drop any protection of their nascent industries Yet all along US has discreetly managed to protect its own companies from foreign competition under the guise of national security. They even managed to foist their toxic debt onto our finance sector who were gagging for free trade to have access to their banking, at the expense of much of our wood industries as tariffs on imports were dropped. This has led to the US economy having a much higher differential between rich and poor than europe. And therein lies another topic, Average incomes in US...
  13. About the same as a seat in the local Odeon. 6d got me a bag of chips on the way home. I didn't buy beer till 68. It does show that inflation really only hit after the 70s. It was also the period which saw the demise of the traditional industrial company that held stocks of raw materials for a rainy day, they all fell foul to asset strippers yet firms like that would have been a more robust means of seeing us through the current crisis.
  14. I am sure your experience is better than my knowledge of the process but let me explain a bit about the theory: Wood starts off at ~40% moisture content, about half of the moisture is liquid and occupying spaces in the wood, this migrates to the surface fairly quickly where it can be carried away if the surrounding air is not saturated. The rest of the water is weakly bound to the wood structure and this doesn't start moving until the surrounding cell water has gone. It is the removal of this bound water that causes wood to shrink. Before kilns everything was air dried and milling was often done in the winter when the air relative humidity was high, i.e. it has a low capacity for evaporating water from a surface, and the ambient temperature is low, so there is little heat available to supply the energy required to turn the liquid water at the surface to a vapour in the air. Also as it is cold water takes a long time to migrate from the middle to the surface. So everything starts slowly and water migrates evenly from the interior. As summer progresses the temperature goes up, RH goes down and water moves more freely in the wood, so everything speeds up a bit. On large sections it becomes necessary to control how quickly the wood evaporates off the surface because if the outer bits of the wood dry down to their fibre saturation point (the point at which cell water is gone and only bonded water remains) and starts to shrink before the middle has lost its cell water then you start to develop surface cracks and other defects. This control can be done with stickers and shade and isn't largely a problem in our climate. We mostly all know that things happen faster as the temperature goes up so kilning gives us the ability to speed up the process but the increase in temperature is mostly speeding up the way moisture moves from the wood to the surface. The problem is this heat also decreases the RH of the air at the surface and thus increases the rate at which it removes water from the surface. Kilning schedules aim to ensure water removal from the surface never exceeds the rate of water moving out of the wood and this is done largely by increasing humidity in the kiln. From my experiments with drying logs in a greenhouse structure, where one is not concerned about defects in the wood from drying, I thought the solar kiln would get into the temperatures and low humidity which would cause problems unless coupled with some way of controlling humidity.
  15. Were you 15 when you got your 11d pint? Actually I think working men's clubs sold a cheap pint but I don't remember beer being that cheap.
  16. I would expect control to be more of an issue for sawn wood, the hotter the kiln gets the more important the control of humidity becomes.
  17. What year was that? Inflation started ramping up around 1968 but my figure for a pint was in 1973 when we joined the common market, we subsequently had a referendum 2 years later and inexplicably stayed in. As you are a few years younger than I...
  18. <pedant>All estimates are likely to be verbal, after all verbs will be used, if it is by word of mouth it's an oral agreement /<pedant> ?
  19. One needs to be careful in whether it was a quote of an estimate. A quote is binding.
  20. Primrose and coltsfoot from Friday, they are in my extraction rack so I toyed with potting them. The coltsfoot may well like the disturbed soil if it sets seed before being crushed.
  21. I liked the shootist except the ending went a bit wrong. Ben Johnson and the last picture show, Clois Leachman an he made it for me
  22. 40 miles away so too far and I only have my Vitara , which is okay a couple of hundred kilo at a time but this would mean hiring a truck so uneconomic.
  23. Yes that's them but they are 40 years old now , I've considered putting new axles on but not found a need so it's quietly rusting away at the moment.
