  1. I can do it for you John. When do you need it done for ?
  2. Always address any correspondence via the Chief exec. That ll sharpen them up a bit
  3. Mmmmmmm dont know about the Lockjack but the Rope wrench should nt be allowed as it is a prototype !!!
  4. I dont want to be the profit of doom but I had a similar experience, when you go to court for non declaration the speeding offence is not pursued. I got 6 points and £400 fine and apparently that is the norm. Sorry chap and good luck
  5. The Lantra qualification will be recognised also when they are launched. The Lantra format will be (I understand) mirrored by the NPTC in the near future
  6. I have the Halfords professional cabinets they are very good
  7. Only measure what you need to dont waste time taking unnecessary data
  8. Ive got a spare if your interested
  9. And a cambium stain and dead flowers usually too
  10. Get on this people. A very supportive employer. Their apprentices do very well
  11. Bicton run an apprentiship scheme they may run other arb courses too
  12. Those are some long levers there, Crown reduction and re brace. Re inspect bracing in 12months or after an event. As for the amount of reduction without seeing the tree I cant specify. Or take out the existing bracing ,close of the area and let nature do its thing and give a home to some more bugs etc. As for the councillor send him/her some press clippings of fatal tree failures, a vote looser this they WILL understand
  13. Glass houses and stones springs to mind !!!!
  14. Send your photos to your insurer and let them fight it out, thats whaty you pay them for
  15. go to the texaco website you can download them from there
  16. Superb saw bit dated now but at the right price definately
  17. I opened this and said "ah cute" the mrs didnt even look up from what she was doing and said " Puppy?" Am I that obvious ??
  18. understanding dynamic forces and with in the system including the tree is a must, but first you should be able to judge your weights of the species of tree first, this i understand takes time and alot of revising, but once you can do this then you will be able to judge how much force will be put on a system from eg, a 200kg log on a 1m drop would be a force of 800kg forces like this will become visible in the system as friction (glazing on rope) but forces like this can also be lost depending on how you execute the rigging load. eg, would be to make the shock load minimal by letting the rope run and distributing the friction evenly along the rope. adding hardware such as pulleys allows the rope to stretch to its own shape throughout the entire rope used evenly, hardware like a pulley will allow you to lower the dynamic forces compared to natural crotching. My understanding of the Rigging research by Chris Cowell etc show that in a locked off system the peak forces can be upto 10x mass. Obviously this can be mitigated letting it run. Just my 2 pence worth anyway just an insight but we will get technical later i don't want everyone to fall asleep on the thread just yet....
  19. Not sure I can make it. Shame as there a couple of talks I wanted to hear. ( bloody wedding anniversary) Come on Arb Talkers get behind this and maybe next year can be bigger (and not conflict with my personal diary) we ll talk about that Paul
