    Is that about 5 transit loads? I'm up for a couple if I can borrow or hire a truck.and can help ringing up, give me a bell if it's not all promised.

    Pass I didn't buy the record it would have been a friend's. Emily is an acclaimed artist now

    I can believe you could see Emily play but Timon? Was he born then? I was 16 and humming it on my RE 250. I lost interest when Gilmore joined.

    I think the gasket idea is likely to be best but I find UHU from the pound shop is petrol resistant.

    That was the original ethos for the welfare state and has nothing to do with insurance, insurance is a bet just like the lottery or a betting shop. Just look on insurers as being posh bookies, they quote the odds so they will always win.

    I know nothing about guitars but I was at the concert with a Dylan fan, she was most disappointed with his hoarse whisper, Alanis was great though.

    The ones in the know with a tame liquidator keep the same name: owner changes name of company and goes into voluntary liquidation, gets 3rd party to buy back assets from administrator and buys a new company off the shelf, changes name of new company to the old company name which is now available.

    This is the salient point and where the art/science of kiln drying for lumber comes in. Most of the problems of cracking occur because one part of the wood dries before the rest. Shrinkage occurs once the water in the cells is gone and the water associated with the cell walls starts leaving. So if one part is still full of water and the other dries below its fibre saturation point then the wood is strained and pulls apart. What kiln drying or air seasoning does is to only allow water to leave the cut surface at the same rate that water is able to migrate through the wood. Thus a ring dried homogeneously can stay as a ring without splitting as Silkyfox says. It will be species dependent though as every species has a different ratio of tangential to radial shrinkage, when this is high the tendency to pull apart down the radius will be higher and it will also be influence by weaknesses, like those associated with parenchymous tissue (rays and figure).

    Impressive and says something about the construction method with such a perishable timber

    My thoughts too

    Simpler is better to my mind

    I've done it on pines in heathland restitution but whilst the tree dies it takes longer than expected. I have also posted a picture of one where the tree carried on living because of root grafts with neighbours. Sour felling works though and now the trees will be actively transpiring.

    Gary has anyone ever suggested you might be a trouble maker?
  14. openspaceman
    Not in my experience as you would need to sever the sapwood, just cutting the bark and cambium stops the roots being fed but not the sap flow for quite a while.

    When I retired 18 months ago it was £5/tonne but I think it's shot up since, a big chip drying and reselling plant at a power station on the coast takes it for RHI boilers. It dries from green to below W30 in 16 minutes. Anyway with the chip maybe worth 400 but probably much less mass than that in the stand because of open spaces do the costs of moving machines and operating them for a day work out? How about 3 days over 3 quarters one man and a mini digger plus bonfire Or manually fell over same 3 quarters, leave trees whole and then take chipper in but accept the wood for free
  16. openspaceman
    Yes but with a replant condition for on the crop for the next 10 yars. I know but needs must... Anyway it's 2 hours with the Plaisance tops and what's 40tonne of chip worth standing?
  17. openspaceman
    Yes as I said, and from experience, FC measure any bits of the tree over 8cms including branchwood.
  18. openspaceman
    That's 1/6 ha so with a yield class of say 12 there would be at most 40m3 and it looks half that Only those bits bigger than 8cms count in the measure The wording is within the curtilage of the house which in this case is probably the bit from the back of the house to the entrance drive, possibly including the paddock to the front (SE) and probably not the paddock to the west and almost certainly not the bit to the north with the trees in it If you sell it then you restrict yourself to 2m3 per quarter, we're in the second quarter in 4 days. I'd fell 5m3 of the biggest trees within in the next four days, thin out any less than 10cms dbh in April and then fell 5m3 after the thinning for the next quarter and I'll bet there's not anything left that's licensable after that
  19. openspaceman
    it's not a stupid question and IMO hinges around whether the trees you intend to take would otherwise be final crop trees or whether the ones you take will improve the remaining stand. Thinning licence won't entail having to replant or expplain you will recruit trees from the remainder for restocking.

    All well and good but "fail" is a pejorative and deprecated word in this context. "retraining if current work was not meeting the standard" perhaps... I have had chainsaw refreshers in the last 5 years plus I attained a couple of NPTC qualifications but to have refreshed all my qualifications at approaching 65 would have been a waste of money, it's one thing viewing them as an investment when in your 20s but the rate of return diminishes greatly as you get older such that I now only get to do domestic work where no one asks for tickets.

    Did you replace the outrigger bearing with the pump? Belt tension correct? Oil seals are effective in one direction not the other so in cold weather it pays to warm up the machine gently to prevent a depression at the inlet port which pulls air past the seal. Once air is in the system it cannot settle out and hence overflows the breather. Because of the way the side pieces of a gear pumps are pressure compensated often the damage is done as they get forced sideways onto the gears. Cavitation is a separate phenomena, also worse as oil thickens, where the depression behind the gears causes a vacuum bubble which then collapses,this can erode the metal. The first grapple loaders I saw had pressurised tanks to try and prevent cavitation, perhaps that was because they came from Sweden. Both result in loss of power.

    From what Bustergasket says the seal may not have been reseated properly but that only means they never fixed a pre existing fault under warranty. I wonder if the gearbox has a breather? Blocked breathers can cause seals to blow.

    There's a good bit of lateral thinking. We saw beech bark dying on the south side when exposed to direct sunlight in 87, IIRC it only needs the cambium to get above 70C to disrupt the proteins. Think of all those trees home-owners ask us why thy are dying on one side and no sign of cause other than the patch of char and ash 3 metres away. A small steam generator and ducting perhaps...
  24. openspaceman
    The twigs are dead. The rot symptoms are to exposed heartwood from damage years ago, the adventitious growth from the wound wood has also died so it has problems. Also doesn't look like ash and poplar would be my guess

    These axles usually have the type and serial number on the square axle tube. I found it was cheaper to buy the axle from a trailer manufacturer rather than direct from Knott- Avonride and it seldom pays to buy from Forst or GM as they simply buy from OEM suppliers and mark up accordingly.
