Once again each man is his own savant! (perhaps most would not have a job if that wasn't true?) >>for me, maybe just a ol'gymnastics thing , but i can feel if i was standing like that tree, that the pressures are wrong for the next 'trick'/roll/throw. >>man doing his own work and getting in a...

After surviving another 'rush' hour trip on I4(rated most dangerous US hiway for about a decade now); i swear i wasn't going to capture/post these lawnmen trees(this is hard work, they got'em down, not huge undertakings etc.), until i came around the corner further and saw this surprise...

i think this is really all math; each thing you do/don't do during setup gives a logical instruction to the mechanix that plays out when light fuse/backcut enough to set to motion. . i think hinge strength is forced or 'forged' by the FORWARD pulls to target; then spar rotates on hinge with that...

Complimented! . Have tried to show should have a side dimension in hinge/face for management of sideLean CoG Watching 3 force points in rigid force container/domain of tree: CoG as initiating force,and then responding compressions and tensions w/their length/angles between these points...

i must say i consider you as a 1% even amongst our own hear; Also, as one that shows has tamed stepped faces and can weigh and measure them predictably would make you more likely to read ahead and avert BC beast. . But anyway, on this side of the pond, guys don't admit to having short bars...

Certainly, certainly; the outer constraints are the genetics then the condition of the tree. We view things at full power, to determine the range here; then define all else within those confines. Weaker, more brittle Ash etc. would not hold itself to the works as well, would not give the...

So, simply for a load that the CoG weight is offset from the path to target; >>we just offset the pull of the tension fiber positions to fit where Nature already has these pressure patterns. Many hinge patterns will give the same fold forward resistance to the scenario >>we pick one that simply...

TAPERED HINGE LOGIC In my own internal imagery of tree shape as a weightless, rigid container in which exists CoG weight ball that gives the shape weight force; just as battery empowers wiring. >> i think of the narrow path across hinge as how i urge the empty,weightless shape concept to fold...

Nice fiber pull seems balanced inline; i think of the hinge compression (pivot) to tensioned fibers (leveraged support) pattern across hinge As an 'eclipse' of pattern change thru the hinge; as you alter the CoG sideload angle across the long axis profile/length of the hinge. If keep same...

BARBER CHAIR When playing with immense force ranges; anything can happen... . i think of Barber Chair as a split decision; In felling, some part of the tree is always pushing back as tree comes forward; Tree Stall is when this back pressure matches the forward pressure AND tree stays whole; Tree...

Pic on crossed cuts, tapered hinge, purposeful step-dutchman; shows again faceCut bypasses down or across vertical fiber stack. note rotational/leveraged push/pull combination in last graphic (arrows) (Older pic;drawing style probably late 90's) . .

. Sure, hope i show transition from half-square to rake trick to see same math in all 3. i show with heavier garden rake that gives surer plumb-bob , squarer head to use as pointer in face(tines up); but then extended as you say could get fairly heavy, just always did as shown, pix are what i've...

Fall Footprint = Direction , Size . Mostly for tree falling. . But in climbing,i've used the 45-45-90 rake trick below accurately enough, repeatedly to: measure height of tree in back yard if layed across house, where would it reach?/ take measurement. then measure off usable yard space(box) for...

Before laying one of these magnificent beasts down; we often doublecheck the projected box/area/fall zone/footprint. . Basically thru geometry from a square face/ square tools for direction and any 45-45-90 scaling or 'stick trick' scaling evenly for reach of fall in that direction. . These...

i seek to work by feel; so played with hand saw cuts in air when clearing branches, and hung on them to fold, pushed back open, cut some more face/backcut/ played with the face/hinge/sidelean mechanics; if head wasn't heavy enough, pulled on with rope to imitate sidelean. until i...

Shows hinge theory applied to side lean. Work to make nominal force yellow fibers not dominantly populated / only nominally populated! Allow hinge to take advantage of in place forces/mechanics; not eliminate those aids. .

To extend disclaimer: i've worked mostly in midFlorida, with certain range of species, and not with frozen woods. .

For hinging in general i've studied all my cuts i could before/after and any i could try to decipher of other's cuts forensically. . i try to see/ examine in regular felling, cross compair to climbing and heavy bucking. i think in heavy bucking top compression, most severe compression is to...

Sorry for delay, have had both brain cells at high speed swirl in think tank; trying to get depth of field rite on fiber stack sometimes takes awhile fer me to come up for air or light she says.. . Burnham ol'friend i was so much hoping you'd join our humble hinging thread! . Viewing issue, i'd...
