  1. I cannot deal with the lop and top but could do with some logwood, 11 miles west.
  2. Trial runs to Belgium atm, still only £5/tonne
  3. We have a layby out in the wilds with a privet hedge at the back, I refer to it as the AA box layby, all the recent (post 1991) arrivals wonder what I'm talking about.
  4. Same as mine, I could occasionally complete a call before the battery ran out. 1988 I think.
  5. I thought we were referring to self propelled tracked machines

    Hi-viz

    Yes the theory is that orange is less attractive to insects
  7. The surface waters of the oceans exchange CO2 with the atmosphere, the current equilibrium is such that 45% of the additional CO2 evolved to the atmosphere since industrial times is held in the ocean. The significance is that the oceans have been neutral to slightly alkaline but as CO2 forms carbonic acid in water extra CO2 is pushing the pH toward more acid. This inhibits formation of chalky deposits, things like coral and diatomous creatures that form sediments on the sea bed. Limestone and chalks are a great store of sequestrated carbon from when the earth was quite different from the 10,000 years of benign climate in which current societies have developed.
  8. Do any 9" and up tow behind a transit?
  9. How heavy was the trailer? What was the total weight? What was the MAM marked on the plate of the vehiclee? Anyway get a B+E test booked, it will be an ongoing investment
  10. Yeah, I wouldn't have swapped and don't regret my days but there's no going back. We were doing hardwood about that time for 25p/Hft cut and extract and keep the cordwood in exchange for clearing the site, often burn up with grab. I could do with a load of cord at Black Dog if you know of any?
  11. Wealden clay is fairly easy on the saw too but the nearby bagshot sands cause a lot of wear
  12. If you have an interest please consider joining Tools And Trades History Society
  13. But HM revenue will visit you with a bill if they consider you employed and paid them and they didn't get their chunk.
  14. This looks similar to a yard I know in W Sussex where they have a similar stockpile problem. Having converted arb waste to smaller sizes (mostly for charcoal making) I haven't the energy but it may be a prospect for someone with enthusiasm.
  15. This is also my recollection, we used to skid onto cross bearers at the stacking area, which then filled up with sawdust. Yes we did have to resharpen frequently but the chap doing the conversion woulkd often use a larger saw ( Stihl 044 or Husky 288) with a short bar and semi chisel chain, which stands a bit more damage as it doesn't depend on a single sharp point. The main reason for changing to shortwood was more to do with manual handling at the landing.
  16. Kob offered this as an add on for their boilers, none I dealt with used one and we could burn chip to 40%wwb with no visible smoke but a steam plume in high RH weather. The dryer would not have been very efficient as it used hot water from the boiler to blow warm air, vented to atmosphere, to dry chip in a delivery auger. Theoretically biomass should have enough energy to evaporate water and burn the dry matter up to 80% mc wwb but of course there would be no spare heat to use, unless you use a bit of cunning.
  17. Here is a video a friend in Canada made, I have posted the link before. Since this time he has run it on woodchip but there can be an issue with bridging. The chips do need to be dry <30%mc wwb I expect. [ame=http://www.youtube.com/watch?v=yOlu7DdX1gI]Pellet Stove App.wmv - YouTube[/ame] You will see it is basically a cross draught gasifier firing into a standard wood stove with side opening door, so as not to have to cut the stove the wedge is made to seal against the stove and the stove door. The main issue with chip is their higher restriction to gas flow, so there can be difficulty in getting enough primary air through a grate and maintaining the correct secondary air ratio. With wet chip the primary combustion is reduced, less offgas is produced and it is diluted by steam hence secondary combustion never gets going, the firebox never gets hot enough to feedback radiant heat for drying so the fire smoulders and gives off blue-yellow smoke. With my boiler if you cannot raise the flue gas temperature above 140C it will always smoke.
  18. I'm similar again Stubby, just pruned an apple for my daughter, ringed some logs of an oak I had felled for a neighbour and then dozed off at 15:00. Luckily my real job is not physically demanding. I was shouted down at an early FCA meeting when I spoke against attracting youngsters into the industry but it did change dramatically for the worse. When I started piecework felling I would earn more in a day than a bus driver would in a week, and that was cutting pulp at £4/tonne. 20 years ago I was paying a feller 14p/Hft and he'd make £150 plus a bit for the cordwod and petrol was relatively cheaper then. When I finished (closure of Sudbrook) I would still put 2 29 tone loads onto artics with the County and be home by 17:00 and not have much expense other than 5 gallons of gas oil. You need a lot of optimism to finance a modern forwarder and haul 100 tonnes/day just to cover expenses.
  19. Am I alone in thinking that a streak of blacktop throgh the countryside is aesthetically offensive? It could have been toned down a little with some white shingle rolled into the top layer.
  20. This guy did a couple for a local charity , he might have moved upmarket a bit since http://www.rogerday.talktalk.net/index.html

  22. Any chance of some pictures? How does it knot? String or wire?
  23. In the days before teram and other geotextiles wire tied heather bales were used under road formations across wet ground.
