    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...

    Tying climb lines together

    Am always trying to show the geometry view. Here this is shown in the Overhand of own self to me is a 90degree device, horrendous therefore if wrenched hard to it's worst axis 90degrees more to make straight line with Overhand in it. Rope as loaded onto a great ship and formed, but in loaded...

    Blake's Hitch slipping

    i think if work ropes enough can even feel a rope saying it doesn't lend to seating around host that well for this once familiar with requirements. Kinda have to listen with fingers. And then also kernmantles not flattening enough to give good area of contact. As another factor, generally...

    who needs a winch (hard lean tale)

    As the POTENTENTIAL for builds gradually in single increments, so then the inefficiency of the frictions compound at a greater rate of building against(but from Zer0). Still the inverse of the potential is needed in distance, no break there. So if 5x potential actual yield is 2.9xEffort, it...

    A Teenage Tragedy

    The other haunting local nightmare i didn't have to be there to feel the chills is a tale of 3brothers, 1 of the remaining told the story. All worked together as a well known local tree service bearing the family name. . This man told a story of his brother he had always known, even sharing the...

    This is rigging!

    Looking at 1D cosine as 1D rope support column(s) against Load, Load = Number of equivalent support columns X (cosine of 1 support column xTension). If multi-legs (2) of support, for cleanest number examples must assume self equalizing (pulley on Load). . Cosine = 50% @60degrees deflection...

    Easier to let it run w/ lrg. or med. Port-a-Wrap?

    Yes. Abso-friggin-lutely, and Radial is always different than Linear is what Ancients tried to tell us so long ago!! . Compound frictions(radial only) can work very hard against ye, or may be commanded under your employ. Linear frictions increase more simple scalar; 2x as far = 2x as much...

    Distel hitch... Ba da ba ba ba (I'm lovin' it)

    Looks like are showing double pull of half weight style in the 2stage and extended friction list in 1/2" on 1/2"? Same rigidity? Go fatter then host with these systems? . edit: Serial dual systems work in other stuff rope and other as primary system hitting pretty hard, but leaves some minimal...

    aluminium port-a-wrap. is that a bad idea?

    i have the most faith in the math describing the organic pattern; the logistics of the formulae very sound. i have the least faith in yes people's assignment of materials mated to particular CoF values . These are meant to be guidelines, and also conditions subject to contaminants, or even...

    Distel hitch... Ba da ba ba ba (I'm lovin' it)

    Wow Brocky! . i think these Friction Hitches in general are all tune-able mechanics in some ranges. . The 2 stage Friction Hitches with hardware in the primary raw force stage_1 and then a choice of all rope Hitch in upper stage_2 seem quite logical progression(also with heatsink in stage_1) and...

    A Teenage Tragedy

    A chipper is as if a monster kept slave; forced to chew wood, while connives how to get the meat and blood it actually craves. Anytime go near the thing, know that is what are dealing with ! See the monster, and know that this is no game. . Went to a local funeral of such an accident. It was...

    Easier to let it run w/ lrg. or med. Port-a-Wrap?

    No, sorry just closed that out this week and not cleaned up sigs on sites. Not sure of next direction at this time, kinda have accumulated a lot.

    Easier to let it run w/ lrg. or med. Port-a-Wrap?

    Linear is easier to predict and understand, and more in the terms we intuitively expect, even when looking at radial. Radial anything has surprises by comparison; the Ancients tried to highlight this key point to survive this long to us. . In theory, a larger radial is easier arc on the rope...

    Why 1/3 notch depth?

    Starting or changing the depth of the face cut; changes front face position of mechanically the most key central pivot, benchmark to measure everything in terms of distance/angle from. Unless backlean, then is a key receiver not an initial position. . Treat as tree is weightless rigid form...

    aluminium port-a-wrap. is that a bad idea?

    Don't have access to such toys, sorry. Mainly chasing the maths here, of what happens at what CoF, materials just representatives of those numbers. They should be good tho, at least tested by others more reputable. Nylon on Steel CoF from Engineering Toolbox shows the LINEAR FRICTION standards...
