  1. Essentially yes, the saying is that you need the 3 Ts for good combustion: Temperature Turbulence Time Just thinking about temperature and wood burning the consensus is that one needs the firebox to reach 800C to completely burn wood. Hence the firebox in modern stoves are lined with insulating bricks. This is easy to attain with wood at sub 20% mc but when you have more moisture the heat required to vaporise it means the fire can struggle to get hot enough. The turbulence thing is so the air and combustible gases mix well enough and the time is the 1.5 seconds that the combining gases dwell in that 800C temperature to burn completely.
  2. I think the wording used is "supply" but the notice that has to accompany a non registered, none woodsure supply says ambiguously: If you sell wood in volumes of 2 cubic metres or more in England you must provide customers with this notice: “This wood is not suitable for burning until it has been dried. You should not burn wood until it has a moisture content of 20% or less. “Wet wood contains moisture which creates smoke and harmful particulates when burnt. As well as being harmful to your health and the environment, this can damage your stove and chimney and is an inefficient way to heat your home. Dry it in a sunny, well-aired space for at least two years, keeping rain off in the winter. “Radial cracks and bark that comes off easily suggests wood that is ready for burning. Test the wood when you think it is ready for burning, ideally with a moisture meter. First calibrate the meter and then measure a freshly split surface to get the best reading.” To my mind this means if you stack roundwood in a container(s) of 2m3 and display this notice you could sell it to a customer for domestic burning. They could take it by the boot load until gone. The question arises of how much work is economic to process it a bit smaller to make it attractive to the ordinary punter and how much extra you would have to charge. I would say not worth it as the labour cost would probably be greater than half the sale price. If you were near my home I would do some voluntary labour for a couple of hours for a boot load but wouldn't part with any of my pension for it. I would not put willow or poplar in a load as this will devalue it.
  3. Whitebeam is a good shout. I would be more concerned about the shade on the house in the afternoon. You could just cut it back to the previous cut points.
  4. add 10% petrol when you fill in cold
  5. That's to control reverberation (an-echoic) rather than reduce transmission to the outside.
  6. sand might be better
  7. The wooden "rounder" in the video I know as a "stail engine"
  8. Too posh for me so I use https://www.robertdyas.co.uk/kitchencraft-stainless-steel-steaming-basket-23cm and cook all the veg in it. It is flimsy .
  9. I've knocked more than one fingernail off from circular saw kicking back but the cone splitter tried to rip my arm off.
  10. I wasn't asking, just observing ;-). Mine was an imperial thread but I fitted the hycrack replacement by tapping out the hole as the thread pitch was very similar.
  11. Do you mean this pin marked red? My cone splitter has a threaded cone tip at the bit marked in light blue
  12. The tips have a bastard thread. Some of the american ones which were imported had a bastard UNC thread (IIRC) which is only a slightly different thread pitch to the metric one, so the female in the base cone can b tapped out to take the metric thread. Somewhere I have a tap from when I did mine
  13. If you PM an email address I can send it, very little space left to upload.
  14. I thought the big difference engine wise was the 261 is a stratified carb with two choke tubes whereas the older 260 was conventional.
  15. Dan did suspect no personality 🙂
  16. Yes I had forgotten that a similar tonnage of neonicotinoids are used on pets as in agriculture.
  17. I think they are used against flea beetle in OSR establishment too. I took a poor view of beet growing in the 70s over the way British Sugar dealt with farmers over the soil that was washed off in the factory, a problem with most root crops I expect. Apart from knowing nothing else about sugar beet I think that OSR was too difficult to establish in the 70s and, like maize, it could only be viable with biocides. The principal arable crops are cereals, a farmer can grow them for two or three years in rotation and then the yield declines too far because of the build up of pests and weeds that a break crop is needed. This is where OSR came in as vegetable oils found new markets but they needed pest control to be profitable. I think big farming has reduced costs to the extent small farming cannot compete on cost and that has lead to a higher proportion of output being from big farms, a bit like forestry and small woodlands. Now my limited knowledge of neonicotinoids is they are systemic, the seed is treated and the active chemical gets taken up by the plant (and the soil to some extent) any insect eating or sucking the young plant is poisoned. All well and good but these plants also flower and the chemical gets in the flower and the pollen. Neonicotinoids have only been in regular use for 30 odd years but given how they work and the drastic reduction in insects in that period why...
  18. this is why you get to walk in and do all your maintenance and felling and stacking in the weald then wait till May to September to extract.
  19. I guess I de ash my stove about 9 hours after the last log goes on, I prefer the ash and any remaining char to be cold, it can then go straight on the compost.
  20. Close call, good to think about. I was always a bit wary of using the stump gobbler with a wander lead, to easy to stray into danger. I was much happier sitting in a barred cab with a Marguard windscreen.
  21. You need something like this: from:https://wordhistories.net/2016/08/22/curfew/ Originally it was probably to prevent house fires while people slept and this cover evolved to make restarting the fire in the morning easier, before matches.
  22. Then the bits of biscuit fly everywhere.
  23. On the same theme; when one is out on a walk and decides to eat a cereal or protein bar why does a corner pull of, leaving a small piece of plastic wrapper separate from the main piece.
  24. I was surprised when I first came across one but supposed it was to do with litter. I was similarly surprised when I first came across a ringpull that didn't come off in my hand, by then I had got used to not carrying a can opener to make two triangular holes in the beer can. Recently in an attempt to embarrass me into cooking my share of the evening meals my house sharer has taken to buying readymeals again. Tonight's was interesting as it was a lasagne packed in a one piece glued punnet, much nicer than a plastic tray, it burned well too, after the dog had cleaned it.
  25. This may provide an idea https://fractory.com/metric-bolt-torque-chart/
