    Running bowline on anchor sling

    i think an upgrade from 1x arc180 (as in single Bowline) to 3x arc180 (of as a Double Bowline or Half-Hitch conversion to Anchor Hitch, to each side for Girth to Prussic etc.) is an upgrade to as a pro-level performance from basic level (except where curiously noted for Blackwall/hook as 2nd in...

    Running bowline on anchor sling

    Running Bowline, Timber would look at as 'single bearing', right angle pull as like tinyurl.com/abok-chap21 that starts with Half-Hitch(terminating) forms of security for nip positions and evolves to Timber even with the preferred fig.8 style, 'bull-nose' of Round Turn(RT) around Standing...

    Bend radius for rigging

    Dynamic changes in where arc bends as an impact vs. change factor at rest. Somehow as like terminating vs. flowing electric, water, air etc. thru their force channeling devices. Force going to arc vs. cranking around it.

    Overthinking, a Minimal Friction Hitch model

    TY/YW, i don't have every chapter so marked of venerable tinyurl.com/abok-online / the knotting bible, but did mark chap21 as so often used and can sit down at any computer and jump in. There is very natural progression of thoughts/forms extending from previous starting with Half Hitch, that...

    Overthinking, a Minimal Friction Hitch model

    No have not, see that as a dizzying wormhole chase. Am not formally trained, beyond some trig when also training in gymnastics to apply numbers and feel them somewhat too. . i consider a right angle pull on host as a 1D directional force pull, 'lengthwise' as 2D(1D for grip, another D for the...

    Overthinking, a Minimal Friction Hitch model

    Linear Direction is own geometry quantity that persists from input , even after linear conversion to radial arcs of rope device that force ports thru. i find these things to be true, and have given me truest answers in my searchings over decades. For i have purposefully and constantly worked to...

    Overthinking, a Minimal Friction Hitch model

    Wow ty Dan Thorton, that puzzle piece intersects exactly to where i go from "Half-Pro" to "Double Half Pro" (kinda making fun of naming as i do), following naming of another full wrap around after workhorse Round Turn upgrades to Double Round Turn(4th wrap around would be Coil by this naming...

    Overthinking, a Minimal Friction Hitch model

    Linear, focused axis of single dimension (also as sole benchmark/cos rest is measured from), vs. Radial, dispersed axises broken out to now 2 dimensions(from single linear 1D benchmark), is always of great importance to consider. This matters mostly to architecture loaded rope has, but then...

    Wedges or Rope?

    i think, The compressed part of the hinge is the actual common shared pivot as bench mark to all other force points measurements. Try to see (in sound, solid, monolith unit) as if tree on hinge is weightless framework; >>except for a cannon ball of weight called CoG, within framework perimeter...

    Rigging Prussik

    YES. Blake's, Tautline, Open/1 leg pull as input to Prussic(ABoK Lesson#481) shown for model_A of Equal tension rigidity and diameters. _A as an open/single input leg at full tension rigidity matching host of same diameter. _B as closed , 2 leg pull so half tension rigidity onto matching host...

    Rigging Prussik

    Concept: In round on round, grip around is one thing, but grip displacing into more powerful and proper. If pull from both ends of Friction Hitch as divided inputs of half load >>need smaller/denser to bite into the full loaded rigidity of the host lifeline, but the half load powered Friction...

    Overthinking, a Minimal Friction Hitch model

    This has been a great friction hitch for me for UTILITY use; It is a Blake's -1 turn as pre-fix and post-fix of uninterrupted Round Turn(RT) as work horse. i recommend using for life/rescue proven hitches, this is easier to make tho for other stuff. Actually before "Blake's" was popularized thru...

    Alternative to clove hitch for rigging short trunk sections

    Short answer: Running DBY with a pre-fix of a Half Hitch, sometimes several Halfs in weak piece to spread out stress and better chance of keeping if piece starts to crush or crumble during lowering. Side forces are real on target, shipyards would put a 'spanner board' across top of crate...

    Logs bounce.

    Had another problem 2x; where 5-10# 'log' walked end over end to cause damage. One at the end of a very tough, but well executed massive Live Oak limb damaged over a house seemed no one else wanted to do because couldn't get a crane in to fancy house on city's favorite large lake . Almost done...

    Predict the pull

    Note in Samson model, the player needed an equal and opposite against(so used other column) and attacked the mighty target column of cos1(bearing massive weight properly of roof inline downward column)across at it's Achille's Heel of cos0 perpendicular to column as greatest leveraged angle. i...

    Predict the pull

    Of course in pretightening friction is foe, but friend in lowering thru same system (if enough load to pull clean and not hang/seize). Likewise, friction at a pulley on linear pull is foe, but same friction can help capture a 'purchase' (of rope from the loaded to the unloaded banks) during a...

    Predict the pull

    Fighting stretch factor also, would look for compounding frictions to seize against the high power potentials shown. . There is another build pattern to compound quicker exchange of velocity for power (root concept). By not just serially, simple 'daisy chain' to add another system at end with...

    Pulley One

    Sum Thoughts: Some of best threads take on life of own. . i prefer a gentle giant clean machine model of having overwhelming force readily available, and only part of this spice employed. No redline to capacity necessary to work, always plenty of available 'headroom' to overtake if needed. ...

    Rigging rings as snatch blocks

    A regular block would give more softer bending radius with less friction. i think hitching to something would allow bend radius X statically; that could be too small for cranking around same arc/curve dynamically. i have done like this, especially to industrial size clevises from local phosphate...

    Need Rigging Pictures

    Unfortunately i guess should always and all ways pitch one such as this: cuz this game, ain't no game !
