    falling some 16"-24" diam poplars on Saturday. Shot with a telephoto lens by my mate big Tim.

    Matthew, the answer is probably that your timber is significantly less than the 35-39% m.c. you've quoted! Assuming that your meter is reasonably accurate, you're probably taking measurements from the timber surface (up to say 12 mm deep)??. If so, bear in mind that the surface moisture content fluctuates with the weather because wood if hygroscopic. Suggest you split a few rounds and take a few measurements from the newly exposed core material. That will be a far more accurate reflection of the total moisture content. Several previous post allude to the fact that surface moisture readings can move rapidly..i.e. within days. This is not a reflection of the total moisture content of the timber...just the surface moisture condition. Cheers

    I misspelled P. ferreus; sorry!

    Hmm, good pics RangerMatt. Thanks. Can’t add more to the above suggestions but it does look like P. ferrous to me...but then, I think I’ve only come across it on a couple of occasions in the past cheers

    Rob..well it was probably less noisy than a 2 stoke engine, so maybe no ear protection necessary; speeds of moving parts would be a good deal lower than on chain saws , so maybe flying particles not so hazardous; and of course don’t forget ...both the bowler and top hat were both developed as head protectors

    woow ..now that is a great find! surely Fred Dibnah had one of those?

    David, Interesting tread of yours..thanks English landscape painting from the C18 onwards is a wonderful resource and I for one could quite happily spend a decade or two reviewing the content of this archive. Fast forward to C20 and have a look at the work of Paul Nash. pre C18 you will find Chinese graphics of interest. Last year, I realised I'd missed this Deep Rooted- How Trees Shape Our Lives at Whitworth Art Gallery exhibtion...Drat an double drat

    Pete, you’ve already fessed up in a public forum; so, there's no place to hide now! Seriously; Sloth and others have given you good advice i.e. honesty and sincerity is the best policy and nobody would wish to punish the man who takes the first opportunity to correct a wrongdoing once better informed . Veg and Paul Barton also make some good points. I would add that, apart from trespass with criminal damage, inappropriate use a creosote could also be viewed as an offence under the EPA, and possibly under the Control of Pesticides Regulations....so maybe a nice box of chocs of bottle or vino would be a good idea t'boot. Good luck Pete Bannister......in no way knowingly related!

    Drew, that's really interesting. Thanks for the post. I couldn’t really make out the details of the rigging from the video. Looked like a fall factor 1? Apart from the tree, what were the 'elastic' or friction generating linkages in the system, other than the webbing sling itself?
  10. Pete Bannister
    Well presented video showing the effect of fall factors and sling properties on impact forces and failure. Sorry if the link has been posted before. Watch the movie at the bottom of the page. How to Break Nylon & Dyneema® Slings [Vid] — Knowledge — DMM Climbing food for thought!

    Oh boy..pass the anti-inflamatories please. My back's hurting just lookin at that:thumbup1:
  12. Pete Bannister
    Brilliant

    The gappy joint is probably the result of drying shrinkage. On drying, almost all species shrink mostly in the tangential plane ( i.e. at right angles to the radial plane). The least drying shrinkage occurs longitudinally. If you look at the gappy joint, tangential shrinkage would account for it (rather than inaccurate joinery!)

    Nod, very interesting subject. In other fields of engineering, there are Phd s written on the matter! From an general engineering view, FofS range from around 1.2 to 30 or more. In rigging with fibre line or steel cable 3 to 10 is the usual range. In the case of repetitive cycles, varying environments, and very approximate estimates of forces or where failure cannot be tolerated then the global Fof S needs to be nearer 10 than 3. In broad terms, the more precisely the materials and forces in a system are known the lower the FofS can be.

    HaHa....Yes maybe but its too late now to debate philosophy with a Fungus.

    Hi Gerrit I went to see my doctor: he’s told me I’m going to die..but thankfully its only hypothetical; there’s no proof yet. Was my doctor un-scientific in using that little piece of Bayesian probability?
  17. Pete Bannister
    'Oak SGRs + Hollow + Kd + Wound spread + Crack = Remove' Is that not a statement of Bayesian probabbilty?
  18. Pete Bannister
    Sloth, Im no expert but 'Self-girdling roots' and 'Kretzschmaria deusta' fit the description?

    Just read this fascinating thread. Many thanks indeed to the excellent contributions here. Its hugely enlightening
  20. Pete Bannister
    ha ha Good idea....'some of my best freinds are''. etc.. etc... I think the property was in Neston
  21. Pete Bannister
    Thanks for the explanation Geritt: I always appreciate logic:
  22. Pete Bannister
    Ha..tis all rellative Rob. I'm Mancunican
  23. Pete Bannister
    It'll be interesting to see what that is! Looks like P. punctatus to me?..but I dont think I’ve ever noted P robustus. I thought this FB to be punctatus . Found it causing white rot on previously saturated Beech window frames ( very odd choice of timber for windows! ) in a sheltered S-E facing un-heated part of a brick building surrounded by broadleaf garden/woodland on The Wirral ( posh bit of Merseyside N-W England). Colour has faded a bit now, which is a shame because it was vibrant cinnamon

    David First look at your photo of the larva and I’m thinking that looks just like Longhorn! However, hole through the bark doesn’t look like longhorn. How deep were the tunnels in the wood? any more photos? did you keep any insects? Sorry: more questions than answers I'm afraid
  25. Pete Bannister
    Interesting! David looks like Sirex ( wood wasp) holes to me.. especially if on the south facing aspect.
