Gents I think we know each other well enough now to know we are passionate about our craft, a tad arrogant (if we are not careful), but reasonably evolved I would say. From what I have seen so far I think we heard Shigo's call - muscle and brain......
Well with this post I am inviting you to put on your thinking caps, put judgment aside and consider it is possible I am on to something here.
Truth is wether I am or not matters none, if the turnbuckle is a fantasy and I am wrong well I really do not care as I have nothing to lose by being inquisitive and open to possibilities.
The fact is Shigo afflicted me with his call, and I am now hooked on the science of trees, I believe that I have interpreted his and Matteck's work well enough to be very right in my assumptions. The turnbuckle is a theory that history will prove true. If that is the case then I am the first arborist to make a scientific discovery (whoopie dah) - we humans get caught up with bollocks.
To me the turnbuckle as with other bio-mechanical symptoms and the biochemistry of trees is genius, but not human genius, we hav'nt created this - the tree has. My comittment is to the genius of the tree not to the size of my sword.
So gents I invite you to help me unravel a possibility, attached is my third draft on the turnbuckle, study it, question me over it and help me with the
4th draft. The 3rd draft contains a diagrammatic representation of how I percieve a cross section of the turnbuckle would be.
In the 4th I will have an actual cross section (if I can gain permission to fell the tree). Its all about rolling ribs and the optimisation of v forks or bifurcated branch forks.
Note – The phenomenon of rolling ribs mechanically acting as a turnbuckle appears to be random, as in my experience of all species cited the conventional growth of reaction wood producing pointy nosed and snub nosed ribs (as recorded by Mattheck) is the norm. Based on study of trees as evolving systems I believe that Eucalypts are in the process of evolving the `turnbuckle’ as part of their success story, quantifying that is impossible at this time without the ability to study Eucalypts of the future, but will make an interesting study for future arborists. I ardently believe the evidence covered in these case studies is more than significant enough to obtain funding for a research project.
Gents bare in mind I shared this doc with ISA America and the Australian Chapter, to my surprise I heard nothing.
Regardless I am keen for you to hook in, I am busy this coming week and am away with my sons this coming weekend.
Great to know you - my utter regards Cassian...
