    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 !

    Try Youtube/authors? Wide subject, anything more specific?

    Another home made lowering device

    i look at the suggested screw links as dual leg support architecture. >>favour screw closed and back off 1/4 turn for anti-jam at smallest loss. vs. single leg of support of hook . Carabineer as well 'moused' hook, against carabinier pulling open mostly(and rope keeper) >>NOT a secondary leg of...

    Soft shackles

    Flexible supports(rope etc.) have no side/cross axis resistance so as to give what i picture as an 'amplitude wave' of suddenly leveraged (sine)force, that rigids can't deliver(rigid sine can give lever that whip can't in trade tho). The initial force is the recoil like on wrong/breach end of...

    Where does the knot go on a tied prussik loop?

    Always a few Prusiks for small utility now, but lace on with the seam after the coils per experience making quickies whether throw away or quick release even loaded of simply using Square Knot(light utility only, tie downs etc.). It is always a very unloaded position in the chain, and holds. As...

    Competition is cooperation

    co-arboration? The eagles claw is only as sharp as whatever it can draw across and how(angle, pressure etc.). Make easy work for you, and then hard purposefully work for you too; capitalizing back on whatever was thrown at ya easy or hard. Harder task is more taxing, but then has greater...

    Blake's Hitch slipping

    Rope Seating to host, rules controls of frictions, nips and grips, especially in the most powerful user of these in arcs and apexes. Kinda try to listen to rope with fingers as grooming into place purposefully, it is a machine are making.

    Where does the knot go on a tied prussik loop?

    Personally prefer seam factored out of range of rawest, unbuffered forces as can; as a mantra or blind religion of faith to that ideal. Variances in strength, rigidity, elasticity etc. stirred into unbuffered region of most critical consideration otherwise, but will say is just not me as a...

    Hold Fast: our heritage

    A round load in parbuckle can capitialize on continuous even motion, but the squared cant's type roll gives rests in trade of loss of continuous motion when walking up ramps etc. . A half circle arc180 is mechanically a stroke to me, another completes the cycle; as all these pieces come together...

    * A point not hit, not even by self; is 1 rope/no lanyard; in context of surprise rescue shituation. * . Also, one of best things i ever did, was forcing self to commit to a good habit of bringing up loopie and carabiner setups, to have ready as a standard, not an extra item to be passed up...

    Where does the knot go on a tied prussik loop?

    Okay, flipside/ Devil's Advocate view to you: Mechanically most loaded, rigid rope part support logististic geometries will be the Standing Parts/SParts as raw linear force input positions into the controlling arc radial conversion reductions. Most rigid distortion against system possible at...

    Would knot that ruin a perfect running record? . Duplicity and Dimensions of Freedom to me. 2is1 & 1isNone /Fail Safe Possible limiters on 2 of 3 Dimensions. 1 against gravity, 1 against sway byproduct or shared V etc.. . Rope is king in these primal lessons pretty Neanderthal minimals living on...

    Hold Fast: our heritage

    The say, and can draw as 2/1, but have always tried to show as more, of course not always selling that won either.... As needs no pulley, and is not like 2/1 dragging block by pulley as even better than that is even more! But rather another dimension of easy with the roll/not drag; and then less...

    Hold Fast: our heritage

    Heritage of parbuckle 2x ramp advantage against the load(can use for lift or controlled lower for even sea burials) : Radial 2D motion funneled 180 x1degree power axises into a single 1D power axis is always a logical increase, and decrease/dilution in other direction. Winch is radial motion...

    Hold Fast: our heritage

    Wind and water powered craft, at low friction connected much trade in the old 'flat' world as a heritage; and it has given much to us, but for me mostly adding to a more ongoing thru all time Rope Heritage as a greater unsung hero for much longer than boat usage, that even helped challenge and...

    Soft shackles

    Many things are mixed chains of rigid and flexible dampening parts, or different ranges of flexibility mixed. Car frame to shocks, pogo stick, rope vs chain truck pull, pillow on bed etc. Very thin line of great improvement to me of from normal to pro lacing status in ALL ropework by the very...

    Soft shackles

    Would not the other more elastic/dynamic parts of the chain then provide dampening to the whole as like shock absorber on car, snubber on boat shocking etc. The more dynamic limiters taking the hits, the static limiters just passing the hits.

    who needs a winch (hard lean tale)

    I generally redirect from low on another tree as anchor, potential of 2 xTension, to high leveraged balanced pull to rigid part of target. Then METER force from truck , not use all of overwhelming influence of truck. The low redirect has less leveraged pull against anchor AND prevents lifting...
