    gratitude for applied techniques today

    YW. Understanding the forces that may be produced by the mechanical commands given is very powerful, then why not to invoke. A Dutchman at full tree scale in felling can 'over rule the constitution of the tree as a container' with the shear volume of force produced and set into a bind against...

    gratitude for applied techniques today

    For felling usage. i do identify any early close used to rebound off of as a Dutch treat, to include kerf closes in top hopping over a fence etc. and undercut kerf then cut down to for snap off of smaller branch pieces as a close for support as cut thru hopefully unstretched fibers at top of...

    Neruo Divergence (ND). In arboriculture

    Wow, Krishnamurti - "Think on These Things". Alone in the air, goggles and earplugs doing my thang smoothly, eyes just inspectors of the fingers aftermath, much time for these thoughts in some kind of pure zone. . in the various studies of movement science and awareness we can see not just a...

    Uprooting Hickory

    If ground not spongy(does not look raised in pic) tension side especially, might fall as some side lean scenario w/o rear rope too, all depends. Side fall would not feed into the fiercest falling force like would happen on falls inline to lean axis as loaded power axis, or even degrees to the...

    Neruo Divergence (ND). In arboriculture

    Well, then too, only a narrow band of that prototype survives let alone thrives in the raw Neanderthalic environment of rawest risks, loads, other forces , tricks and traps!

    Neruo Divergence (ND). In arboriculture

    Inductive Reasoning is inverse of most peoples thought process, if one…. . Being able to work backwards, also lends towards more to hitting target on the run forwards in realtime. As Evo says able to do both ways better, I think able to flip spin in head as hit from any angle more 'owns' it...

    Clove Hitch

    Clove to me is a continuous direction like Round Turn, both in contrast to the counter-torque reverse of Backhand base in Cow. . So we expect some walk in Clove, to probably tighten, but that can go too far seems. We see this even in kinda 'Double Clove' of a Taut Line; we backup the hitch and...

    Rigging Setup Design Factor Poll

    10:1 rope, but this is a trade-off with the amount of elastic dampening response returned. So, 20:1 tensile impacted, can ruin day that a 10:1 wouldn't, by shocking support etc. >>Doubling rope to 2:1 support thru pulley has same effect of increasing Load capacity @ co$t of elastic dampening...

    Bowline slippage

    From ABoK Lesson# 478 "There is unsuspected virtue in a few turns of line." -In the The Tree Surgeon section Lesson#1732 "There's a lot of virtue in a round turn." -ABoK shows in quotes like from another Lesson#1669. "Round Turn on the Standing Part adds materially to the strength of the knot."...

    Quick Block attachment knot

    To me fair build for a 1D pull away from host, But I always like Round Turn base on host for a more availability 2D support structure against a 2D pull. Not trying to lessen that in efforts here, but in my own mechanical logic, this is what I see, and where would point .... . 2D to me pull...

    Favorite Applied Physics Resource?

    Studying compound pulley systems, Chinese Windlass/differentials and the 2/1 over own self in DdRT dumbwaiter are key to my understandings and testing of self to same, as chase the rules thru counter intuitive turns and they stay so consistently the same..... Cracking how smaller gear sprocket...

    Favorite Applied Physics Resource?

    This has been a journey for me, and i had lost fm5-125 hard copy long ago, and caught Tom posting same with Sailing Smacks link, perhaps 20+yrs ago and they have been pivotal to unraveling what i have, ty. . But, they were not just magic manuals of immediate knowledge, but rather work, sifting...

    Will a larger rigging ring always make more friction?

    The collective arc frictions that are compounded; are counted in 180increments, but this pivotal work shows can be cumulative sum, not necessarily whole 180arc counts required in that count. The Mechanics of Friction in Rope Rescue -Dr.Attaway In my words: Even as linear list/series of arcs on a...

    Bowline slippage

    Still only 5℅ loss is pretty dang good, but to purist theory and benchmark, pure inline again rules is witnessed again hear. . Logically, to have any bury, must have at least 1strand, and we now have that lower benchmark limit defined in this example, nothing could be 'worse' /less and still...

    Bowline slippage

    TY, amazing, memorable, concise, imagery factoid of just how sensitive this is to these things, very counter-intuitively to this extent. i don't think stiff cable is that bad by comparison.. Just as say each man is his own savant; Dyneema is amazing, but i think we are hitting at it's Achille's...

    Bowline slippage

    Again, i put that on the low CoF of securing hold from the same position, pressures etc. compared to other ropes of a shorter bury of higher CoF. . Also, a smoother taper, for this material seems to take deformity even less well than others too. . Even in not knotting dyneema because doesn't...

    Bowline slippage

    on the coEfficient chart of mated materials: radial(link) teflon/teflon=teflon/steel=.04 dyneema/dyneema is .05-.08 nylon/nylon is .15-.25 nylon/aluminum is .25 nylon/steel is .4 manilla/wood is .5 . The above frictions are exponential compounding multiplier in arc/capstan formulae. >>As...

    Tree work is not for everyone… The importance of listening to your minds voice

    Tune, true and test your senses against the math as can. But still listen to bod, in head or in more Eastern mind stomach, solar-plexus etc. too. . This is risky biz, but less so to those are humble enough to fall back, rather than always blindly charge.. There are those (z)heros that offer...

    Select and Check your anchor

    Pilots are cold, clean calculating, 'Knowledge Replaces Fear', trusting the numbers and 'feel' tuned to mo'fos; when in the focus of their game zone. Pilots have all that tuned up louder over rest of human screams inside; only with more than just all their (like climber) chips on the table.... ...

    Safety lanyard for Bosun's Chair

    Simplest seat is made more for positioning than catching life load. Lanyard, especially adjustable, can be very key in most leveraged, more stable and comfy positioning to better view of work along with main line. Especially see this if main support and lanyard are offset from each other where...
