    Scientists discover how knots work

    i think this will give a window into this tiny knot world. Would gladly have some of this rope and even a Nip meter designed for testing evenness of pressure along length of pinch rollers, to trace Knot Nips. . i think man was tying knots before mastering fire, wheel, lever of even speech...

    Decoding Patterns of Forces

    Part of this was to old argument as sometimes 360 is referred to as "Round Turn". . i think in bigger pond engulfing this, that is true nowhere else; that geometry of forces is a ruling factor in all; and anytime replacing geometry with shear force can be very costly force wise. . So, basically...

    CT tree hitch?

    i prefer(ed) similar only pass thru as to Girth, then around spread to each side and around outside to then clip in more of the 3arc positive try to highlight. Still mechanical stopper against run but i think less need for it, less harsh bend to rope, more frictions and less side force on krab.. .

    Decoding Patterns of Forces

    Dimensions of Arcs model theory of knotting on capstans etc. but w/o maths to show why 3arc Round Turn type based hold against side forces even as lengthwise pulls on host mount by force dimensions. For us pertains very much to friction hitches and mounting Porty to take massive forces not...

    Bullring rigging device idea

    I think he means this is more 3dimensional like ball profile pulling flat to trunk than flatter profile Porty.

    Question on if I should return the rope I purchased

    I really didn't in anyway mean to even imply intentionally I'm sorry when said bought/not sold as seconds, but in fact does look like seconds. . In fact in longer form of this post started/ not completed before resolved I recommended manuf. /gave address,email, phone as science source, QC etc...

    Question on if I should return the rope I purchased

    Almost looks like virtually good enough seconds bought as 1st class? >>would seem no internal damages multiple strands? off color almost seems as id strand..or internal dmg flagger that is now thrown even if no internal damage. src...

    Bullring rigging device idea

    Devil's advocate shotgun: . Playing workflow backwards; Shows soft sling attachment; lots of hangs like this i'd prefer krab attachment link to then soft sling/rope as most modular utility of fewest links . But this could mar 1 reversible side with metal to metal, especially steel krab to softer...

    Bullring rigging device idea

    About as dense as steel but no weldie, 6061 compromise. Larger rounds allow softer rope arcs; but counter-intuitively same friction by this math; then also add strength and weight as device. Standard aluminum not as weight nor strength dense as steel. So must be thicker to match steel strength...

    Bullring rigging device idea

    Very nice! . i would think would want close enough access to device to whip on/off last turn for lowering/retrieval: but far overhead c/would be problem as say . Bottom half of ring supports downward loading of top half and gives friction arc points; center bracing handles side forces produced...

    Gymnastics made me a better tree climber

    So many lessons... . If get on highbar, and kip, kick up to handstand; as long as CoG is over bar as pivot and no inertia etc. can hold a few secs, but eventually CoG will be on one side of bar (pivot) and you go that direction and better have right grip or release when can safely. This is all...

    Negative rigging pry bars

    Cut deeper as stated to more undermine CoG essentially giving top more leverage to help pull own self as also reducing load that needs pulled on rear side of hinge pivot. PIVOTAL CHANGE. . Would always go over top as Tom states. >>I think this takes the highest leverage point and then maintains...

    Gymnastics made me a better tree climber

    Kurt Thomas, Bart Conner and Nadia Comaneci were gymnastics heroes when i was in gymnastics too. . Sorry Tom, so much i have already said, so much here to say, i had to put this aside at first like hiding from a light that was as too bright.. . But, had to come back around as i knew i would...

    Knots for joining two ropes for life support

    Pile and Sailor Hitches to me are amazing hybrid of 2 basic 3arc RT (Round Turn knudeNoggin IGKT abbrev.) crossed forms of crossing ON & OFF host as Crossed/Frapping (Clove etc.) and Backhand (Munter/Cow etc.) Turn type bases. Both and their respective friction hitches(add turns to Crossed...

    My one experience with spikes...I only remember going up.

    L.U.C.K. Labor Under Controlled Knowledge Fer some reason, seems the more ya practice, the luckier ya get! .

    Knot Starting Over!?!

    This is more towards what i'm trying to draw to in re-examination of all hitches etc. to focus on number of arcs and if/how crossed; where understand a group of similarly based hitches and how their differences lend to different scenarios. Seeing the base parts becomes a mnemonic whereby...

    Knots for joining two ropes for life support

    Whenever high loading and/or wear, the extra confidence of more headroom logically seems appealing. Even as it did in Ashley's day as many strength references are made as warnings. . In that time they had high loading, fewer choices, less testing devices and very accelerated wear compared to...

    Taken a step further; cute baby in carrier sitting on lip of chipper, showing low vibrations and noise: Would also be a wrong picture to broadcast that should hurt your eyes; even if machine is off, gun kid is holding is unloaded etc. should be BRIGHT no-no flag or perverse curve forcefully back...

    Good on you checking with them Rico ! (must be having a weak moment, said something positive!) . Laws of man say you can walk out in front of moving vehicle and have right of way in many scenarios. >>Should teach kids law of physics says that is stupid as is an over-riding force path/line; so...
