    i used to sandblast on bridges; then later on deep mine equipment with water/sand with so much power could still see spark in darker corners. Small grains can do all that as ally, but then too can tear up rope internals as foe, can do same razor thinned edge of steel tooth and face plates that cleave apart. Number of angles on each tooth to get right, to restore full functionality (then right amount of exposure /depth gauge to wood type/temp). . Amsteel is crazy azz strong Dyneema , 1/2" = 34,000 tensile and floats! (4" harbour tow ~1,800,000# tensile) Thus our thin Dyneema slings only need few strands of true Dyneema, add polyester cuz so slippery (teflonic?) and for color etc. >>we use nylon as more elastic than polyester; but much more rubber-band in polyester than Dyneema/or even more static Spectra builds. Longer molecule for more strength , less water absorption than Kevlar. Powered baby sand gran,eats it all. .

    i see what you mean; but meant as these surfaces hone to edge, that cuts yes as surface sides can also serve to cleave apart wider; >>all in all a destructive cutting/grinding machine when given power. . i believe i am quoting some far off memory about sand 18 sides/edges average. >>but in any case;i think gives proper working imagery model to go by. . Have same imagery (by any name please); for grains of sand working into rope internals, then silently hidden and protected, are powered by loaded usage to work back and forth; and tension contraction of loading and unloading itself i think, to include cranking around arcs in lowering as we do; to saw rope fibers degrading strength over time. Flat Rope/webbing less strength loss on arc static on branch less deformation, but would get eaten up on lowering, and has 1 favorable bend axis to not deform too much, all round rope axis are same efficiency loss leveraged/bent at any angle . . This is why mountain/rescue disciplines go nuts if step on a line(let alone run car over), can press sand grain(s) thru jacket to theoretically give problems much later/unassociated to cause due to wide timeline >>treat rope/gear as 'sacred'. >>downgrade ropes in timely fashion from primary lifeline also overhead lifting and lowering positions. (to rule out this cumulative damage, and other low level/slow damage of UV, air etc.) . By extension would expect a clean carpet to last longer (and be lighter).

    Sometimes cut to Dutch in direction of proposed pull is needed to get snap easiest. Can even cut face up and backcut down and throw rock in upward face. As long as solid stop inner and 'nose' of face still allowed to turn passed that point. . Like the slant cut for more linear compression of wanting to push itself apart. Twisted, torqued can be hard to calc where to plot reliefs and can get more conflicting forces, especially if cracked etc. so is not a monolith of 1 unjamming piece but rather different sections that can jam each other. . Drop across spars gives more determinable compressions and tensions, and spaces from ground/sand. . Consider peeling what bark can if in dirt on dirt side, even blow dry out dirt, then might try rinse to keep sand out of works. 1 grain of sand uncrushable silicate averages 18 cutting surfaces per grain and chain saw can use as sandblaster to turn chain knives into trying to cut with back of spoon profile!

    i've been around some of this, just captured here for reference if anyone needed tho; as not easiest to find info; part of heritage of tree work etc.. . Mostly for me, bears out parallel work to view as different facets of same principle gems, verify theories etc. of rope/flexible support materials handling. . To me finding the lemonaid ; the yin/yang to flip to the strength of weakness; is this 'weakness' gives the ability to tell the difference; where others are not affected at all/ or not so noticeably by the forces etc. Similariliy>>if i can show the big guys how i have to do something, they save a lot of effort might not have been able to sift to on their own, at least not so immediately, especially if not looking for it etc. , or even them trusting their can be a lighter finesse way rather than bulldogging thru all , all day. Sometimes i even purpose-fully position self weaker to the shituation than necessary,just to find these paths... Wire rope, is so much stiffer than rope, so must adhere to all the pure inline strategies even more so; and illustrates this to us at every turn, literally. Wire Rope is (mostly) stronger than ropes, but 'expresses' more of this Achilles heel weakness to deformation/taking support column out of line even this minute bit. Then this benchmark model guides many thoughts; to constant grooming knots during manufacture to this pure inline profiling. Then, as collective inefficiencies and weaknesses stack to multiply against efforts and safety, they are simply forged to be less at each stage, to extrude less loss at the end of the loss multiplier chain(s). . . For me, The saddle is the wider set side of the clamp. You ONLY saddle the LIVE end/side because the Ubolt side of clamp would not be as 'soft' would deform cable more. >> So give softer deformation to loaded / LIVE side of cable for most strength, deforming only 'DEAD' side with the 'sharper' Ubolt side of clamp. note even mixed to try to give best of both worlds to either side is errant, fails earlier in the 'staggered' /alternating clamp arrainge-meant than the proper ,only saddle LIVE side of cable/side carrying loading. Then keep watching same loaded aspect view in rope workings. . Rope, to me has same characteristics as cable, only rope isn't as sensitive of a read-able barometer to these changes as the stiffer cable of the flexible support family(tension only support of rope, cable, chain,web etc. / non-rigid supports). So,the more exaggerated reaction of the wire rope re-affirms this principle as the wire rope brings it so much more closely into view by it's magnification/ exaggeration of what happens in rope etc. . This is 1 place where i directly get outcry of 'pure inline' to measure the lay of the systems as a 'roman column' of support for rope/knots/rigs.

    i've sunk outriggers on pads about 3' evenly(still scary) w/crane close to work; thus say:crane only as good as the ground it stands on. . Seems piece too big for a static, vertical pull(but hard to tell). Let alone leveraged angle, increasing in to impact. I look at angle of boom to work, rather than distance. Would seem crane reaching over building, would seem low angle. Should never impact crane, straight up , clean only. . i'd hope any crane operator would only pick straight up on static target, CoG below choker. >>anything else gives multipliers of weight against crane. >>no telling size of crane/capacity; if experienced operator etc. . To me, on this, it would seem fairer if Darwin came and got crane operator as the injured party thinned from gene pool. .

    We had to drive to neighboring town once , i had to pick up something, guys were unloading tar buckets from long horse trailer when I got there. . Customer said couldn't work unless trailer moved from under tree and truck wasn't back yet, trailer often moved empty. We had some words, I owed guys 1+ hrs travel however came out. . Put rope around bunch of buckets, pulled forward with truck, 2 pulls did it careful stacked 2 high left them on trailer end. They were lifting nose by moving bucket out of it 1x, changed to less distance, move bucket behind axle to lift nose 2x per move. . Like not sitting on load and then instead hanging against load and Also like using effort and it's equal/opposite force against load, I try to connive 2x from every move when can anywhere, always watching the equal/opposite thingy. . >>But sneaking climber leg lift in before frictions at higher leveraged point than usual pretighten by friction reduced efforts can be game changer alone!

    Thanx, things get much larger for real power w/o that differential trick! . This is supposed to be a rebuild from Ancient Rome: . Hamster cage cranes were all over later on, show thru history, i've often thought mite have helped with pyramids >>but always just see ballast/lever crane lift arms, not rotations of wheel input. Many builds like this simply didn't make it thru the portals of time: . Of course all power produced transmitted against load by rope after condensing distance into smaller container. This is real radical stuff, shut down a town, kill anyone that talks during proceedings( had to keep airwaves clear, can't let anything get out of hand, have to notice everything) >>Each leg of line input goes to several men, that are pulling leveraged devices that then delivered to each leg of line those men's pulls amplified and combine the whole for pulling force! . Even with all this, even in rotational input that can keep inertia going from all force input(no reset for another pull) still 'flat'/linear/straight on problem solving compared to compounding, turns rules back on self of differential/Chinese Windlass! . i think this type of raw understanding of extreme loads and compounding against, especially with rope, compares to men at sea, trusting lives to rope, wood and sail, not sure if Earth was flat and forging on, army training manuals, rope rescue etc. are as close to a rope heritage i saw as in working trees. . Of course now have many mechanics to buffer between us and the raw work. But just as Doc Shigo invited to 'Touch Trees' , can get out of touch by being buffered from raw tools to raw forces.

    i always try to show a more fluid/abstract imagery of power as a flow of force. Compress so much power as a psi, into half as big a container(distance) have 2x power etc. covering less distance >>slower output movement than input movement in same time slice. Play it backwards, input to opposite end and take output from where input was: lose power and gain speed. >>assUme 100% efficiency total input of force x distance will equal total output force x distance. >>this gives several attacks to figure out problem, and a checksum (verification) as well (should match). . For decades nothing has illustrated this to me more than a differential windlass(evolved to chain hoist) invented in the Ancient Orient. So much power change in so little space by playing the fiddle on the numbers and Nature dances along so consistently on base pivotal concept that can see it around this counter-intuitive turn! This concept then carries into gear boxes, to make so much change in so little space. Actually all power leverage changers are differentials between input/output; Chinese just compounded the effect, giving more illustration to the laws. The difference in total distance input/output is the leverage increase multiplier of effort, so much so, law continues even here. . Not much to do with tree work; except a front row seat of pivotal principles deal with daily(just different facet view of same gem), in rope. and how the mind of man can capitalize on them! Confined by the rules, but then so empowered by them too, if can play the chess game right when door opens to it! . Old Ship Windlass/Capstan winch pretty cool man power But, the Ancient Chinese Windlass certainly is it's own marvel. . . Power ratio from smaller to larger drum will be same for any pair 1/4" difference! >>Larger size crank input for more power, or changing handle to hole on crank for less power (faster speed to reposition, or lighter load etc.).

    Wish I had a do over on that... So tried to sub one! . Just as i tend to say numbers in ABoK are not knot numbers, but rather lesson numbers, of rope mechanix with a knot shown as example of the lesson. >>here was hoping drawings would present as more conceptual components to take other places than shown. >>The collective orchestration of principles merely example of a thought thru assembly. . Certainly, learning to sweat/swig for high tension tweak w/o thought, instinctively in passing can help a lot in many things. Distilling out how to use any 1st class lever flexible rope or rigid bar to bear weight, effort and equal /opposite as inputs. Digging to find 2:1 collection in anything.. Scheming when can to even capitalize on byproduct. Calcing best leverage points etc. Tricking force in before frictions etc. . All good component skills to assemble a whole strategy. This is just example, but true fave! . Climber can set tighter than ground sometimes, then if lock off high ( when safe) to limit amount of elastic line in mix, to provide tighter more immediate support. Or have ground crew only do actual lowering, anyway less dependant on less of them, to keep more time towards cleanup etc.

    I used to have large shackle wet ground numbers off of that I used like this as lower but some friction , in between choice of block vs. natural support. Low friction + heatsink more accurately. Was klunky heavy compared to what see now. Had pin and key cabled to shackle so was usable in bight. I always carried about everything on belt ( she notes had stretch marks on back for 2 yes after stopped/ lightened up); but had this sent upstairs special. Even tho generally went into this foreign land armed fer bear. . Pre-tensioning reduced in mix, but found climber has access to pretension against load BEFORE FRICTIONS. >> by sweating this key zone, or providing equal and opposite of climber effort to same >>longer drops between support and load found helpful to climb higher to not just pretension before target load, but to preStretch that segment of line also. . <iframe width="854" height="480" src="//www.youtube.com/embed/ZwxGuIK_VgU" frameborder="0" allowfullscreen></iframe> . Note how climbs removing self from load helps to not weigh against pretension efforts, but then adding bodyweight to pretension efforts is in itself a type of 2:1 change in scenario, then climber effort doubled as well. Sweat/Swig to leverage across support column of line is different, and a process of 'taking purchase' ( old world sailor term) of rope from system to tighten line and/or move load as less rope in system now.

    No Spanish Windlass twist lever? Nice tho, source? Robert, You are inadvertently scheming to cultivate cheap clientele, that when pass your name along will focus on how cheap you are rather than how good. . i really wasn't meaning to rush anything, just have the key 2 man stuff lined up to knock a big chunk of effort out w/minimal effort and at key safety points (actual felling) and large/bulk drags. To leverage something large with minimal input, just precisely timed. Like a well timed martial arts strike being worth 20. . In Economics there is the "Law of Diminishing Marginal Returns". 1 person input >> 1 person output as benchmark scale 2 person input >> maybe 3x benchmark , gain per person ratio calc =1.5 . . . 8 person input >> maybe still greater than 8x benchmark but a falling marginal return, people messing around, getting in each others way at some point actually less than 1x per person originally benchmarked rate So they cut off the inputs at marginal drop or inversion to max profits. . Key here tho is that if can pick time of 3-4hrs extra man that you and helper together are doing 4x what you could alone @ 8x safer for the whole job by shaving off working drops etc. >>AND NOT FELLING ALONE FOR SAFETY AND TRUE TRUCK PULL KEEPING FELLING TO TARGET >>setup for helper timed to this most critical time slice. You are really backing up , and at higher risk by the numbers other-wise Especially if that man gets you a job or 2.

    That is fair.. . If going ahead here; should NOT work alone. Robert, seems you would know someone that can drive truck for a few hours only, for $50 or so of your $1000 and learn to bill that as $1100. Get a hell of a plan, with maybe 3 ropes already in trees, ready to pull, and throwline already installed in another cuz ran out of ropes. Can have separate line for reach on truck and connect each pre-placed pull line as needed to line on truck. Then bring man on site, to immediately dive in felling trees, buck,drag etc. Lay down all you can w/o crossing them too much. . Try to cut out 80% of your risk and 50% of your work in those few hours just having all shots on the pool table all lined up. Might even start with easier hand pull fall to get co-ordinated with worker etc. Have short tag lines ready to use for dragging as full a lengths as possible to target location. But move like ballet of pre-set motions thought out like a chess game. Timing is everything, align their time to help thru the most critical and bulk work. (shouldn't really need truck here but pix can be deceiving) . Talk to someone that talks for this and they end up getting you a few jobs; that $50 paid for itself several times over and over! You are less tired, mite even get another job or quote in too! That $50 becomes a sprawling investment in several directions and cheap insurance! . Highlighted tree i'd try for high throwline to center, trace down back and tie off low, knot on back of tree so ends up facing up after fall. This gives best leverage, seems like could flex this one too, and the line down back can help brace,curl top towards you more confidently than running Bowline to same area, pulling forward at sharper, unbraced angle. Rather than a gradual braced arc; also more of a rotational input for rotational output kinda look to me... . Please make sure with 'stick trick' or other 45 degree measure to make sure there is room for falls. >>@ 45 degrees cosine = sine, so 45 degree sited distance on angle to top should equal height to fall where are standing etc. Use wedge as anti-sit back and some help serving forward. When using truck etc. remember don't need to hit with all truck has. Part of tree already wants to come forward (generally) and some doesn't. Just need to pull with truck and lightly upset that balance and let fall. Similarily, round log on ground see as ground contact point is pivot, half of log wants to roll forward, half wants to roll backward, so just sits, inertia sets in and that is what you fight, upset balance to forward and maintain new inertia. Not everything is bulldawg;that is just a blind view! . Need to throwline high leverage on strong leader, if twinned side by side; consider pull both for balanced pull. >>but watch for weak crotch, if twins come low to stump, would fall separates or bind to monolith so don't crack up and separate from backcut etc.to be individuals not moving together and possibley even binding against each other . If can flex top can put some ready, self acting spring in system(to draw forward when weaken hinge enough w/backcut) AND draw CoG forward some too! i see tree as weightless form, CoG is total weight positioned in perimeter of shape, shape itself is just handles and sails to engage the CoG thru. Best if can rope higher than CoG to have leverage over, and also possibly flex it forward too. Make perfect facing, no crossed cuts especially from cut perpendicular to grain. Facing is what allows tree to roll forward, like removing chock from in front of tire. Don't cross cuts etc. so system doesn't bind against self; just permits and aligns a path of least /virtually none resistance. When i've been stuck alone, maybe even guys too busy, what i should NOT admit to.. Super tighten pull line and have pulley that serves line pull to side halfway on pull length, with rope that leads to sawyer to pull to leverage line sideways when hinge thin enough pull rope that goes to pulley that then feeds to bend tight one to leverage fall. . Or the real stupid thang: heavy duty pulley inline far from fall, to pull tree that feeds rope back to truck 10' from tree to side, back farther than tree. Cut so far, jump in truck instantly w/o walking in front of fall 100ft.; to pull tree. . Can kill self blindly bull dogging heroically, or turn as much of this as possible into a brain game! You might not be able to get anyone else to clean/haul that up for $200; so why only pay yourself that much? >>that ties you up with grunt work at low dollar; rather than bigger dollar with mo'brain than bod work.. . Similarily if i rented stump grinder, all stumps would already be cut, bulk clean-up might come later as i werk grinder to death for every penny. Similarily rent a splitter, try for weekend rate, have a good helper and try to make that thing only stop to re-fuel,cooking right on thru the nights. Line everything up to keep any money spent on help or gear to get most usage out of. i even used to have a hole dug to back splitter into so wasn't so high and easier to lift or roll large wood up onto iBeam etc. Keep specialized tools moving to their specialized tasks when renting etc. Get good enough that helper essentially does same for you, making you the specialized, high dollar machine to keep moving not held back too much from pumping money thru. Even stuff out so don't have nickel and dime stuff wearing you out and slowing you down from making larger dollars! That is still starting out small, but more strategically! Especially if might consider mite not have a 30yr.run ahead to figure out all this to then really get started.. .

    For me, in my imagery... . Normal Tension escalating all the way to Tapered Hinge etc, has a pull and also safety mechanical fuse/release/tearoff on overload. Normal Compression escalating all the way to Dutchmans, can Barber Chair, overcoming whole tree container of force, not just a few tensioned strands >>Compression does not separate on overload like overloaded tension, the train keeps on coming full bull ;is fully confrontational w/o relief of mechanical fiber fuse shear >>compression forces can bind, seize, tree can come apart in Dutchman in contrast to just whatever overloaded tension strands simply tearing/shearing on over load being sacrificed as fuse. . Tapered Hinge generally gives full tour on hinge control until tearoff, as a ballast against sideLean, like sandbags out to the counter side of lean to balance to center Compressions/ Dutchmans only adjust on (that side)face close as more of a finishing touch/adjustment mostly i think,after tour on hinge. >>exception would be kerf type Dutchmans, but still allow some movement. >>actually to invoke the most Dutchman response, i think logically takes purposefully hitting compression HARD to the rebound with the reflected force >>Don't want to make so much as a shelf tree sits on in step Dutchman, or po-lightly rolls off of step, BUT rather allow tree to 'think' can run like race horse in direction it wants(lean), then let the close on 1 side act like were just letting build speed make harder jerk on leash of movement allowed to then revert to chosen direction(targeted facing). So besides the other factors,the slamming speed needed for best response more risky endeavor. Dutchman is more of inconsistent 2 part machine earlier, before so much full tilt/ tearoff as we are used to >> forms an over ruling face within a face of competing,not flowing mechanic WHILE CLOSER TO VERTICAL ANGLE!! . Swing Dutchman to me (some terms change in localaites some) is combined Step Dutchman push to center in concert with Tapered Hinge pull to center >>w/o countering face close on other side as a Step Dutchman and likewise w/o any tension hinge fibers countering spin on compression side that normally is anti-spin.(So normally always leave at least that tuft of fiber on sidelean side to not have spin w/Tapered etc.) . Dutchmans seem can give the most power, but then that power can tear mighty tree apart etc. So in full scale felling more dicey, especially as put swing in mix. i'd think too risky, in full scale of amplitude felling, with so many variables would be the WHY Dr.D. would have stopped teaching it. >>always potentially playing with power, flirting with death, so trim the most extreme, risky end to make safer practices. >>This can put too many chips on the table to lose to some upcoming hand; it's more volatile, it's in the cards to get a losing hand.. . Swing Dutchman can be very wild, sometimes have even shaved tree off of stump just before destination on sweep to keep from over-swing past target. Swing D. pushes and pulls in concert, in same rotational direction w/o restrictions of countering close or pull on the less active extremes of each >>in this way the truest like marital art strategy of working both ends against the middle with targets own forces to me Just too powerful, unwieldy, too many variables etc. to walk so close to devastation w/o occasionally stepping over line as flirting with forces at too far an extreme . In tree is to smaller scale;safer range of forces. BUT, doesn't have the leveraged breadth across stump of large felling >>nor the weight and leverage >>these input things give more power to Dutchman response output So in tree, longer,more leveraged loads give better response >>but really work the SPEED factor more to makeup for some lower forces and leverages. Like slamming a top harder/faster into a kerf facing for mo'better hop across over fence on ground etc. . Dutchmans , especially swings are good mechanix to know, understand; but mostly then to be able to NOT accidentally invoke and conjure ;especially in full scale felling ranges and speeds that it takes to make them really show their stuffs! >>both good, bad & oogly! . Tension support happens during trees whole life, slamming into Dutchman more of our own contrivance.

    Pulleys, to non-moving points are redirects only, they do not increase power or reciprocal distance(speed). >>Pulleys against Load divide it smaller for more power; >>Pulleys against Input Effort, divide it smaller, for less power, but 'extrudes' more reciprocal speed(more distance in same amount of time as input) . If Truck pulling SOUTH, target tree EAST pulley on anchor pulls SE @ 2 X 1000 X .707 (cosine of 45, half of the span of 90) >>purist view, for calc forces 'expressed' against anchor, nothing to do with Load(target) and Input(effort) positions. >>pulley against tree position pulls WEST @ 2 x 1000 x 1.000 (cosine of 0 degrees deflection from pulley center line) . If truck is built and rated for it that is plenty of power band for 1000-3000# confident pull if not the whole band width for conservative rating. Goose Neck like ball in bed?? But playing with power, want to gentle giant, bump and tease lightly when can, not just always bull dog. Graceful power correctly applied, with plenty of reserve; everything constantly weighed and measured with eyes as it commences , ready to head off anything before it becomes a run-away force! i think i came up with that knot, just call it a loose splice Dress down, groom out long so is logical working unit, no slax. Maintains best geometry i think, imitates strongest splices in that way. Set so it can't escape. How could it jam?

    Prussic 1000#:>>try to stay under, not really a hard line, severe consideration otherwise; >>don't like the hard clamp of Gibbs/cam over this load tho >>FYI after years of experimentation, the arc for rope cams turns out to be a Natural occurring one of course: Nautilus shell arc! . Actually i think want many plans, having played with tools as went along. >>know what takes what to deploy, motions polished, best way to store to that end. Know time investment over pulling by hand etc. >>polished moves like a gunfighter draws the right pistol, from right place and shoots target clean. . Truck is going to depend on access to good ground, but is most powerful, lowest human effort. MA needs an anchor ( i think of as an electrical ground connection) , as does MCRP to invoke more force (leveraging amplitude from the electrical ground connection). Kit needs many tools and strategies, in smallest space of war vehicle >>job needs them deployed productively for what ground and anchor points it presents. >>master chessman has many moves; but chooses correctly for cleanest action by what is on the board!

    Ummmmmmmmmmmm no thanx, ye ain't built rite! Wow, guess i don't read all sections of forum; tough break, bro, really sorry to hear that. Is that what new avatar is about? . As far as other drones... . This is from Parrot drones, Jumping Sumo down to $30 this season,used to be like $150. Android controlled, not too far wifi tho. i don't have the lights, so battery may last longer to 20 minutes. . This thing has a camera(not HD but usable) on it can see on fone, is fast, JUMPS 2feet up or forward!! >> always lands rite! For $30 great way to chase and harass dogs, cats and our Cockatoo during his daily reign of roaming free terror against other pets, wood work etc. Has audio, but not played with that. They have a sleeker Spider model too, just thin spindle between wheels, camera, no jumping tho >>looks like something you'd see rolling inside of duct work on a James Bond movie!

  1. Kenny,
    How's it going?

    I AM coming south to hlton Head SC with a stump grinder or two and a skid steer loader.
    Are you interestd in doing some operating or sales work in FLorida. I'd like to skip back and forth between SC and FL with the stump grinders. Don't rememer where in FL you are. If that doesn;t work for you maybe you know sonewone looking for work.
    Let me know.
    Thanks,
    Daniel
