    Knots for joining two ropes for life support

    Our loads in rigging run way beyond bodyweight and some get high impact drop too. We let loads run thru frictions to slow down sometimes etc. Going large but not too is the production sense on how money is made. This is a ruff and tumble biz, with literally everything on the line with knots...

    Let's define our terms

    Most dramatic Barber Chair i look for a front face spike upward tapered from inside most bark in tact; rear of face/rest of tree sheared from face. Perhaps rear face/rest of tree balanced or pitched over face spike. In most classic version i thought it might be proposed to teeter on top of...

    Friction device

    Important note, the eye can be fooled. A single Turn and Half Hitch has only 1 radian Pi power arc of Nip and Brake forces and Round Turn has 3 such power arcs. On the graph above jumping backwards on the exponential growth rate shows single Turn left way behind; not in the running... This...

    Friction device

    Traced this link down for what i think is very key vision into brakeForce mechanics on bollard type simple pipes like Porty. But would then extend to cranking capstan, why to always keep at least 2 turns on drum of winch (so no raw force possible to termination) and even inside the secret life...

    Knots for joining two ropes for life support

    The PACI is an incredible resource and effort. And quite a list of authors. . Agent_Smith and knudeKnoggin may be 2 of the best knot minds on planet. . i do think chasing strength has brought us many things in it's wake, but can be as real world as auto racing for development. Also to guide...

    Friction device

    Pulls up the trunk, or any pull 'lenghthwise'(ABoK) rather than right angle across host mount should be double bearing at least(prefer self adjusting), especially with taper, especially taking hits in flat rope( webbing) or round rope as most mechanically correct against worst angle of...

    Redirecting Rope to Limb Walk

    Trying to bring numbers to life and show >>there is enough upward support force at angle >>but only if loads more force pulling sideways than for the upward support. . Would want to be leaning way some as ballast to side pull off balance, and remainder of force is upward column support for rest...

    Thoughts on MA

    i believe Maasdam is 10:1, would rather use pulley sets. >>Maasdam is crank back and forth, pulley jig is continuous direction input. . Truck pulling thru 3:1 pulls many things. Can hand pull 5:1 at 5x for speed then at 8:1 with 2hands to tweak. Can stack 3:1 x 5:1 also . prussiks/minders very...

    New DMM 'Director' Carabiners

    Raw potential strength would be determined by weakest position/link in chain. >>Gate side/half of krab >>gate pin(s) at least 1 for axle>>thinnest piece>>pulled sideways! so i always think of carabiner as a well moused hook , the mousing as guard and to help keep hook from stretching open, not...

    Straps vs ropes question

    Force induced into turn(s) gripping tree will be from legs # of hammock support, and loaded angles. i think minimizing the multipliers is strategy for this target. . Flatter 2 leg hammock support/less teepee will load same lacing much more (that will grip tree) for same task of support. set...

    i had stretch marks for 2 yrs. after not wearing saddle from hours of carting gear in air with me. Ultimately, committing to taking slings, carabiners, 2" pulley, long lanyard on every climb was biggest boost in creativity and l-earning. These are professional modular components of pivotal...

    Knots for joining two ropes for life support

    Seems to be like stiffer more delicate 'glass' fibers at critical loading to me in imagery. Like feels the backpressure of the coming arcs and stretch losses as goes into friction arcs carry outside of knot some. Forces are higher outside of knot, and runs into impacts of change at full force...

    Redirecting Rope to Limb Walk

    @Jan_ Will have to go over link later, thanx! Stepson became engineer(and Master's last yr.!), but i'm no school boy; just (well researched) treeman slop of made up imagery to observations and research etc. All the alpha,theta,sigma symbols seen in this stuff kinda look like Greek to me.. ...

    ~6' fair duty spanset roundsling choked to eye as extension, or in non-primary position dbl. sheetbend to tail of line. Make Cow as usual served me well, other extensions as well. Works as Timber extension too. i look at Timber as a pull away from stump thru tree, a very linear stop seats to...

    Petzl guideline on choked carabiner anchor for spar work

    A quick-link / screw-link(or clevis; but wider is weaker in either) has 2 strong supporting legs vs. 1 leg of krab that is more like securely moused hook to me. Also many times quick-link is shorter(and narrower) to lessen the leveraging affect on the only rigid device point in flexible chain to...

    Butterfly can be to isolate weak section of line, give midline eye; but also if lay 2 ropes lines with ends overlapping some and pick up make B'Fly where the ends end up being where the eye would be makes a fine Bend. Zeppelin certainly worth a look for Bend tho. B'Fly eye loads more balanced...

    New DMM 'Director' Carabiners

    . i hope you keep drawing too! Very realistic weight feel. . What catches my eye is a( reversed) D type flow of off balance/not chain link style krab >>then more straight D side (for loading) is given to gate/thru gate hinge pin rather than solid (and larger)spine side. . Train eye to catch...

    New DMM 'Director' Carabiners

    Brocky very nice! I could never draw and brother always could.... . I think mite more invite force to carry down straight solid leg line? Force line here to me shows leveraged equivalently from 'hard' and 'soft' legs in equal balance. . Gives leveraged pull on 'hard' solid leg as gate side...

    Truck Loading with Block & Tackle

    NICE! . We sometimes did truck force to overhead tree pulley to load other truck or trailer. Tag line to side backed by turns to allow drift and throw to target. . Keep soft , inline angles. Part of which can be low redirect pulley so no upper pulley lift against pulling truck tractions. . Pull...
