  1. Why only 60C Ian? I dry at 120C for 24 hours, I don't think I lose significant mass in VOC.
  2. Me too especially to work on. The 261s I've worked on have been standard non electronic carbs, I have yet to try a newer one.
  3. Further to the above graph I've shown another pine log and the two logs that didn't get burned at Xmas absorbing moisture. I've run a short experiment with attempting to dry a log under the same conditions in winter, it's a bit unfair as my workshop is attached to the house so some heat will get through the kitchen wall plus of course it has been exceptionally warm and dry in all but the last few days down here. Underneath I have rejigged the graph to compare the summer drying of pine in days albeit 6 months apart. I was surprised that it dried as much in winter as it did, given the caveats above, but it looks like whilst the summer dried log was basically okay to burn at day 25 around 20% the winter drying if it continued would take 5 to 6 times as long. Whilst it wouldn't be wise to use this as a means to getting wood ready to sell it probably makes it worthwhile to carry on splitting and preparing if no other work is profitable and covered space available, although I did notice some bluestain on the pine log so it wasn't drying fast enough to prevent fungal attack. I still need to do the forced dryer experiment but back to work on Monday PS images are blurred as whilst uploaded as a graphics file the site hosts them as jpegs
  4. Yes having a monopoly is best for profit so creating a false monopoly by brand loyalty is a good ploy. Like TCD I'd justify my use of Husky saws in my type of work 30 years ago but I'd be daft to think nothing had changed since, one thing I am aware of is that power to weight seems to have improved with the Stihl 260 and 261s I pick up occassionally nowadays.
  5. I saw loads of british gas golfs at malcom harrison auctioneers hixton a few years back so may be worth a look.
  6. Pardon? Dog food was often horsemeat anyway. Assuming your typo was hitting the H key instead of G: I doubt it would have been for horse but rather for ruminants. The bruising machine made the leaves palatable. Being a legume it will have high protein and composted should be a nitrogenous fertilizer, this benefit is lost by burning. Gorse is an indicator of high potash and phosphorus status, so the land only needs a bit of nitrogen and grasses should out compete the gorse. One of the reasons for swaling would have been to produce new gorse shoots but most common grazings had become infertile as a result of repaeated over grazing that they would not have supported much gorse ...and there's a lesson there for the age of stupid thread: the tragediy of the (unregulated) commons.
  7. Make sure you know the radio code first
  8. Yes we have this when folk go on leave, a month and the battery won't start the car. Given a small car battery is 50Ah and when it's 50% discharged its life is shortened, 30 days drain at 30mA and the battery is close enough to be damaged.
  9. Should have an interesting tang if you breathe deeply as they burn, copper ions at least and probably hexavalent chromium and arsenic if they are old enough
  10. Much as I thought you meant. The point being the forced air method gets most heat out of your hot air if the distance the air has to pass through is long enough to saturate the air at the exit temperature, The recirculating type lets the air have more passes to reach saturation but the air leaves at a higher temperature *unless* there is some form of heat recovery. Border biofuels woodchip dryer was pretty efficient in terms of heat as air leaving the top of the heap was always saturated and there was a distinct visible boundary between dry and wet woodchip which you cannot see with logs. As the air was always being blown against the constant back pressure of chip there was a trade off between the *free* low grade heat used and the higher electricity cost, which militated against it when the free heat did not materialise. I was denied access to our high speed kiln once it was commissioned so never did work out whether the recirculation power was optimised. So yes a datalogger of temperature air speed and humidity at entry and exit of the dryer should allow you to modulate fan power for the cheapest result but you will still need a bigger container than the recirculating kiln.
  11. As I said in a previous post, possibly on another thread, the two are not mutually exclusive if you don't want to go the RHI route The difference being one recirculates and the other vents the air after one pass?

    Too right sunshine, I'd say you need to be well on the road by 30 and not much chance after 40. Being 64 and commercially inept I have to accept the scraps from your table Wishing a happy and maybe prosperous new year to all

    I did this 8 years ago, in real terms I'm making about the same as when times were good 30 years ago but I was only getting brash dragging jobs and timber selling wasn't doing any good. Was due to retire at Xmas, a bit early but my younger brothers have already stopped work but need to put a little more in the pension pot or die early.

    Knock the mortgage on the head before you jump. I was broke all the time till the mortgage was paid, at the end I was only paying £300/month but that became spending money.
  15. Can this rotate a video that was taken with the camera 90 degrees out?
  16. How well does this stop Huskies leaking their oil and mix? I've never found the best orientation to store them. BTW rawlplugs are old hat, use multi monty direct screws.
  17. Dunno but 9 years ago the boss bought a nice new T190 for me to mulch 100ha of rhody, I loved it, and he said it was only £50k then. I'd buy one but current boss will only look at JD and certainly won't allow me to play with it.
  18. I don't pretend to know any answers but how much rin has fallen upstream of tadcaster, what area has to drain down this bit of the foss? The thing about balance ponds and big sponges is once they get full they don't hold any more back, so something designed to deal with everything but the 1 in 200 year flood isn't going to cope with the weather pattern shifting more rainfall into the winter months. Simple chaos theory says that as the energy in a system increases with increase temperature then the chaotic events are going to be more powerful, and it looks likely they will be more localised, Somerset last year, Cumbria, Lancs and Yorcs this. Big sponges will be more important for maintaining river levels in the now drier summer months. You and I are more fortunate at present, we only have to deal with 60cms of rain a year, Cumbria is over 200 isn't it and one month's worth fell in one day?? Even Ian in Cornwall gets 100Cms (I'm having a rethink about the retirement bungalow now). We've been lulled into a false sense of security with a stable weather for 200years. Even active management like the Thames barrier has been deployed 16 times more than it was designed to. Yes I think some active systems will be needed along with your dredging, like being able to evacuate water holding capacity quickly, unlike a sponge, to maximise the rivers' capacity between storms. It's also an indication of the failure of commercially competitive insurance to spread the load by refusing to insure those that have been affected as they can now see their risk. Insurance works to the society's benefit when it is based on random statistics but not when they are allowed to decline specific risks. We will soon see the same for health insurance when those predisposed to having expensive chronic illness will not be able to avail themselves of private health care. It shouldn't concern me as I've already had a long healthy life and am unlikely to see the consequences but I do have offspring... Although spending the Xmas break alone with 6 women is a bit much.
  19. Could well be so, I'm watching my test logs gradually increase in weight since oven drying, I burned the birch for Xmas, cracking timber the way the bark lights up as soon as on the fire. The ash log is gaining 2 grams/day and plainly the centre will be lagging the outside whichever way it goes. I have never won a coconut, not even throwing wooden balls at one.
  20. Not a repair but replacing with different axles as current tyres are 30 years old and no longer available, no other wheels and tyres fit the hubs and other hubs have no clearance under the chassis. Mind it may be possible to space out the current axles and have som wheel centres purpose drilled, just another thing waiting for my attention.
  21. If it was made post 1982 it needs a plate. In theory an older one could be taken for inspection and plated but I don't know how to set about it. I have a 1986 bateson tipper which I want to replace the axles on and must get round to finding out about single vehicle approval or scrap it.
  22. And 28.6 miles of river to the tidal estuary, not a lot of fall to move water
  23. What we found after 87 was that platypus cylindrus would bore the oak sapwood in the first year but if left in the round would go deep in the heartwood by the subsequent years.
