Both my shrinx thank ya for that Rb, next time i sneak a weak-end pass........ Perhaps overboard on bragging how i Ram-Bulls though; perhaps that takes a real heavy-.........wait like JP weighving in @2700+, i can't even get most posts per pound category with him around anymore!
Don't worry Miss Ginger, Skip-her Sanborn (how can u tell if he is abbreviating or miss-spilling?)did put the lil'buddy routine on me re-sent-ly, following my Maynard G. stuff, much to my big-isle-meant for my opening tune of L-8.
Sew eye see de feet as my mother's sun to Apollo-gize roy-ally! And may i say a very nice amount of reads and writes on this topic you wrought!
Hmmmmmm, Dent's book from 70's(as well as any other document of worthiness and safety i think) says to hinge. He briefly covers side boring behind hinge, and then back (nosing in and reverse backcutting) so you are moving away from the action of the machinery of the hinge as it goes to release (rather than towards the incredible force of the fall while completing the backcut)for strong head leaners and the like. But, i had to pick up open face cuts from an olde Stihl/ Eric Sorensen tape, then fold them in for i did not find them hear. i'd extend a caution on slow or hung drops, it can be not only be fantastic hinging at work but immense seizing/pressurizzing in the face of the hinge(dirty/blocked folding area in closing hinge), and every species in its own class of strength and flex-ability of fibre in this extreme application. i have played and expressed slow drops in the truck pull post (which i must honestly caution as thin territory to stroll); but didn't want to express/inspire that extreme of the scenario for caution's sake.
In Dent's book the hinging, is the real magic , in fact to me; his whole book is about hinging + the rest is background around hinging. He very, very meticulously (wow, yes that is me saying that!)goes over many diagramed views of hinging situations that it has taken me years to digest from this small book, with some more diagrams still twirling in my head still. He shows these techniques applied to some of the most massive of trees, showing how to read hinges forensically after the drop to gain immediate feedback to feed into the next daze less-on. How to look at trees on 2 plains-Trunk lean and head lean.
He teaches to fold the trunk into the face exactly gunned towards the horizontal vortex of the hinge, and adjust the holding fibre across said hinge to compensate on the opposite side of head lean/ or on same side for disturbance on path of fall. And never to cut threw the hinge, to use it's usherring machinery instead. Never to cross the face cuts (except purposefully that he goes into on dutchmans), for the inner seperation or kerf becomes the commnading hinge and is brief, which counters the whole purpose.
Some words and concepts of empowermeant from his book(the ancients beleived that if u could correctly name and call up a devil in someone/thing u could command it), that increased my having to take responsibility of every tree action from him are :"Mechanical Analysis" (those 2 words in his book changed my whole outlook on treewerk), "Compression and Tension" in wood you are cutting, and "Causation" of outcomes. If the gravity or compression powered machine i built to usher movement/release goes wrong, i gave it the wrong mechanical instruction set or something failed strength/flexabilty wise (that i probably should've seen). Either way i glean lessons from it every time after i do it, if it goes right or not.
i've all ways felt that i learn stuf more and deeper, if i group the like factors/denominators to-gather and study them as a whole, allowing their similarities and diffrences in the same realm teach and reveal more concepts in comparisons, textures and contrasts of like things. In his book Dent describes with more diagrams later bucking torqued/ sprung limbs from felled trees; these are the same exact strategies for the felling earlier in his book! Knotching to releive compression, cutting to relive tension, flowing in a direction to release immense force with a strategy in wood fibre using all of this. So i took these 2 matching scenarios, commanded by the same common denominators. Then i drew a line betweeen them on the graph of all; then sighted down that line, to the next rhyming point of use, which for me was hinging rigs in the air.
So, everytime i either drop, rig or buck wood, i'm anal-yzing
, and practicing all 3(at least) with each movement. Because i can identify their commonness, in their masquerade of forms around me to begin with. This strategy is especially useful for all the leverage/mechanical advantage discussions, for each thing of leverage, wedges, pulleys, 2/1inDDRT, 10 speeds, cars, screws, et al, for they are all exactly the same (yes-but diffrent); so all u gotta do is look inside and see the common element to recognize it in all, thereby just learning it can allow you to command so many more things across the bored, and practice and expand them in groups geometrically instead of singlely, also making them more familiar as you recognize they fill around you to view all the time. So i guess i go on so no one could ever say i short changed them, as i putt my 2cents in; but also to reveal the symphony of events i see that must be reckoned with and orchestrated as compounding, denominating components as tolerances become narrower, sighting out self working / positive paths by stacking more on my side than stands against me. Seeking to learn and compare as i go.
So with this view i write and try to extend that more comprehensive and really more efficient and defining information package, in something i am truly fascinated by. For it is the best i ab-soul-utely have to offer!
