    Space should be fairly well common to both, I'm guessing the processor will be about the same speed so the parameters we need to decide on are cost per cord on site, time of purchase, time of sale. Anything else?
  2. openspaceman
    Do you fancy doing the sums for comparison?
  3. openspaceman
    Cash flow, you don't have to fund the labour of splitting and handling for the six months and more before you sell it.

    I'm all for using sweet chestnut You could try here BBH - Burt Boulton & Haywood Ltd Burt Boulton were where we sent utility poles in the 70s and though they have moved (and taken over?) still use creosote

    The pot must have range, quality and type marked on it somewhere, the only other critical bit is the spindle then means of adapting to fit the plate. Compliance would be another issue.

    Yes this is sour felling often inadvertently practised with whole tree chipping when the felling gets ahead of the power station. Bark is waterproof so until it dies and cracks away from the wood it resists moisture loss. Oily bark like birch is particularly bad as all the time the wood is above 25% decay bugs and fungi can turn it into a mush inside the bark. Any species will be suffering a loss of dry matter ( i.e. fuel value) all the time it is wet enough for decay mechanisms. In the bad old days, before you could send a forwarder in at any time of year no matter what mess and ruts you leave behind, we had to make use of this fact to control the rate of drying of birch poles for turnery. These had to be winter felled and often not forwarded till after June. So we had to stripe the bark with a gouge made from a hooped bandsaw blade, 1 stripe for <4" 2 for <6"> and 3 for 6-7" IIRC. Notwithstanding that yes wood does dry in cordwood stacks.

    With the current game of musical chairs in the utilities side of the business there will be climbers on more than that. Bubbles burst every few years so make hay...

    No I hadn't, not knowingly having come across it before. From the description it sound more aggressive than Gano and given the amount of decayed hollow will condemn the tree.

    Some recent finds and a worry, Dryadd's saddle is on a branch tear out wound, probably 1987. Sycamore has formed good reaction wood in the callus but I doubt the wall thickness is sufficient to prevent buckling. 15 metre tree with full crown near a busy traffic light. Second set is of what I take to be Ganoderma resinaceum in a cavity on a 100+ year twin stemmed beech adjacent to a minor road. The third set is a puzzle because although the situation, low in between buttresses of a red oak (Q. borealis), and look suggest adspersum it marks with a brown line like Ganoderma applanatum. If it is adspersum (there is another conk below the soil line in the furrow between buttresses) and given the tree is showing 20% dieback, deadwooded itself last winter and has pronounced buttress flares I wonder just how muck root is supporting it.

    We've had quite a lot of mature birch turn brown and they won't be coming into leaf again.

    He'll be going close by you if he takes the M25 M23 home. I cannot handle the chip but could take the logs if they are sensibly cut but what species?

    Known by by mum as "snotty gogs", I guess the sweetness was important during rationing.
  13. openspaceman
    Where from?
  14. openspaceman
    I'm told told the 800Watt 2t gensets are made on old yamaha tools. BTW I wish they had done the 250 super 5 rather than Bullet.

    I'm no expert by any means but: That's describing a typical greenstick fracture from over loading. The top part of the branch is in tension, the bottom in compression. Most of the strain is taken in tension but when it goes all the tension fibres separate at once hence the straight break, the bit that was resisting the compression now fails in bending mode, often splitting both ways along the centre line. The pictures I've seen of summer branch drop don't exhibit this but lower branches hit by the falling upper branch often do. What they do seem to show is a progressive delamination from a point, just like the glue between fibres has failed. I think lignin plasticises around 100 C (hence steaming to bend wood) so it won't be hot enough for that., some sort of differential drying would add local strain.

    That's quite a coincidence, our lads say the same but it has always eventually started. Mind tabbing along the cess with a 644 would be no fun. Our first mk2 killed the battery in just over 18 months. I'd like to try the jensen spider but the extra cost is an issue

    Damn!

    openspaceman replied to Bren.'s topic in Arb-Trucks

    Interesting point, yes the zinc bath must be above 450C and spring steels will be tempered at 300C but surely that only applies to carbon steels and LR chassis are mild steel?? I'm way out of date but lorry chassis rails were made of higher carbon steel than mild, so they could flex. In the day they were riveted because welding caused brittleness but I assume welding has come a long way since.

    If you still use it check that it has two one way valves, one in the fuel feed to the pump and one in the return to tank otherwise gasoil seems to drain back and let air in meaning you have to wind it over to self bleed before it fires. I don't know why GM's install of the v220 engine has this problem when other machines using it don't. PS also the feed roller palm switches; water ingress, vulnerable and expensive.
  19. openspaceman
    I spoke to a bloke today who said the engines let go at 150k miles, guess what ours did a couple of years ago?
  20. openspaceman
    Really? It seems to snap like a carrot when green.
  21. openspaceman
    Any suggestions? It would still need to be plated at 5.75. ...and I'm far too old to invest in new competencies, even assuming I could pass the test.
  22. openspaceman
    How feasible is it to downplate a 7 tonne Iveco to 5.75 in order to tow a 2.5 tonne trailer on a C1E with 107 restriction note (standard condition for pre 1997 full licence holders to gross up to 8.25 tonne train weight)? With a half tonne body and tipping gear it still leaves a useful 3 tonne payload.

    I have an old one that looks the same as the picture on google and it has been good, I was given it as unclaimed recovered and taped up the tube, replaced the throttle cable and ignition . Over 20 years occasional use and less bulky than the stihl backpacks we have at work. Only other experience I have is the Stihl hand held and it's more powerful and reliable.
  24. openspaceman
    You'll need to verify this but as long as the towing AMV is at least a 1/4 the weight of the mill (ATA) and the brakes are operated from the AMV cab then I don't think they have to to connected to the service brake, whereas a post 1986 trailer over 750kg does have to be operated by the service brake.
  25. openspaceman
    Anything over 750 kg needs brakes unless it's a trailed harvesting implement (exemption for a combine header on a trailer I think). I think the sawmill could be towed as an Agricultural Trailed Appliance to get around the length issue but would have to be towed by an agricultural tractor, max length with 4 wheels is 12 metres
