  1. Red Squirrels and Pine Martens are both native to the UK so have evolved to live alongside each other over thousands of years. One of the red's main defence mechanisms is that they are smaller and lighter than Pine Martens so they can reach right out to the ends of branches which would not support the weight of PMs. This is also the grey's Achilles heel, so to speak - they are much bigger and heavier than the reds, so there is nowhere for them to hide.

  2. Thanks Beau.

     

    On the bright side, the Policeman collating information on this guy's activities is called Officer Dibble!

     

    Put a smile on my face last night:001_smile:

     

    You couldn't make it up could you? :laugh1: How on earth did he make it through cop school one wonders?

     

    Seriously, sorry to hear about your misfortune VI

  3. This looks like an excellent addition to the show. Having been on one of Dave Rossney's Coppice Harvesting Efficiency Courses some years ago, I can guarantee that you will learn a lot from one of the best trainer / assessors around.

     

    Gutted that I can't make it this year as I will be away. Oh well....

  4. The troubles with rapid wear on MS261 crankshafts have all been attributed (as far as I am aware) to the clutch drums with rim sprockets. Spur sprocket drums appear not to have any issues that I have heard of.

  5. The one on the left is indeed an oak apple gall, but the one on the right is a marble gall. They are caused by different types of wasp. The galls themselves are basically plant material that the tree produces as a reaction to enzymes that the grubs secret when eating into the buds.

     

    Hope that helps!

  6. Also check that the bar rails are an even height particularly in that area. If one is higher than the other due to wear (as can happen when running a loose chain for any length of time), the chain wont be addressing the timber at the correct angle at that point and therefore will not cut.
