    Proximity to the lowering device

    Might try right hand pull back waist high w/body lean; guarded ready for leg to stop forward movement if impacted. >>And (s)light upward pull as also grip with left, ready to go with straighter pull w/o upward >>turn some of the maths upside down with direction reverse of upward, not downward...

    Proximity to the lowering device

    Yes, Very nice savable link, ty/stolen/adding to my deck. . The rope as a support column, is sheared across by it's own weight at the Samson angle.. >>It's own weight acts towards leveraged sweat/swig; just no 'purchase'(ABoK) taken/captured from the tensioned side of the system. . In a rigid...

    Proximity to the lowering device

    Would stand ready to take wraps external to Porty, on trees etc.. Part of reason for some lead between 'tailer man'(capstan) and Porty. Sometimes start there and back off extra frictions after /during fist hit. Let the metal take the brunt, be a heatsink and added bark frictions the just trim...

    Why no hitch for SRT?

    Then 150# climber in SRT can descend as easily as 300# climber in DdRT?? >>as both are 150# at the friction hitch to host lifeline Tried to show NOT of 125# climber can't descend SRT as easy as 300# (or even 400#climber) DdRT. Think we should watch the magician's other hand on this. . i think...

    Why no hitch for SRT?

    in my distort(our)ed mind. The DdRT has 2 legs of support yes, and feeds from a single leg pool to a dual leg support yes. Half load per leg of DdRT is lesser load per leg vs full load on single leg SRT , yes. . BUT, A 300# man can descend on a DdRT @150# per leg. >>but a 125# man still has the...

    Proximity to the lowering device

    i always look at it like could get pulled into the braking device like they were open farm machinery of gears that will pull you in and chew you up/hands at least. Always visualized such things as greedy, hungry monsters looking for that opportunity, and give that bear a wider path of respect...

    Bend radius for rigging

    When said handed down, meant surviving chain of custody to that point written; yes that which was used at the time. i think Ashley shows seeing these great friends slipping away around the corner of the 1900 century mark and trying to capture his present and what losses he already was seeing...

    Tips and Tricks

    To the splicing of stuffing the sausage, rubber bungee wraps as gripper can help greatly at some points; and always use NEW rope rather than all tightened and ruff i think. Wow, so much said here! In my imagery, distance is a reciprocal of force; so i try to always have view that naming one...

    Bend radius for rigging

    Well spliced thimble is termination as Hitch not continuation as Bend so yes different mechanic, but still dual legs; now of shared support to eye w/o deforming primary column of Standing Part(SPart)have always thought. . i always read rope from just that same most responding point of arc apex...

    Jailbreaker New type of porta wrap

    TY! Pic of my mental imagery of bollard/capstan vs. rack for friction reducing arcs by either radial or linear list of arcs, inline or cross axis apexes to source, how linear list of apexes needs conversion to this cross axis, with constant or intermittent friction heats, continuously building...

    Jailbreaker New type of porta wrap

    Would look to 'paste' arc pressure firmer against host at hotspot of apex for hold? Jest so ya know i am stealing that "like asking them to solve a Rubik’s Cube blindfolded" line, TY! Frictions to ratio of load, not just linear reduction of set amount. Zer0 frictions etc. Segmented friction...

    Jailbreaker New type of porta wrap

    In my imagery i view the apex of an arc as most responding part of rope to read rope from as seats to host >>like 'Primary Arc' apex gives best nip as 2\1 pulley force position, directly feeding from input of Standing Part(SPart/in knudeNoggin speak; now standard for years for all at IGKT as a...

    Bend radius for rigging

    i think we perhaps see a perfect storm of : Hard stating numbers opens door wider to litigation and so the long game would be to play the hand more conservative, as the survivors do. Could be more conservative food freshness date all the same. . Also, newer materials and stiffer constructions...

    Bend radius for rigging

    Lost during some trimming, the point of ABoK more turns for spread out wear, applies to capstan, porty etc. of even more turns than a knot adding just 1 to bear wear more focused to less as shown in ABoK.. . But the original 4xDiameter host was for standard @ the time stiffness, material for...

    Bend radius for rigging

    i think we are actually comparing separate apple/orange things that have some similarities. i think the 4/1 standard is more towards pulleys than frictions type force flow, and is also just a guide for 'standard' stiffness ropes. A stiffer rope would need more caring/babying (larger)ratio for...

    Why tie instead of rigging carabiner?

    Have used all 6 as shown as suspect all here have; but here trying to show greatest as best, safest path and thus also perhaps thee outer premium benchmark apex to grade rest against in series as lessers of. Always good to benchmark outer extreme(s) as a slice, then define range within i think...

    Looking for smaller blocks to run 9/16 or 5/8 rope

    Would want more flexible rope to make same arc as smaller w/same loss as smaller stiffer line compared. And no chafing from cheeks.

    5/16" Dyneema Sling

    Dyneema UHMWPE has a friction co-efficient almost matching teflon, many times tho as meat of sandwich between polyester(s). Polyester less stretch than nylon but roughly matching strengths and frictions. Longer rope part before friction, can give dampening in chain that Dyneema does not, sling...

    Why tie instead of rigging carabiner?

    Marl leaves an Overhand Knot in line if slip off end, Half Hitch melts away to nothing like water as @Mike Islander says. Once induced, Marl would keep a tighter grip purchased i think. Never had to cut off Marl tho as Mike lends! . Shackle i see as a 2 leg support device vs. a carabiner more of...
