Hidges on limbs

[Dobber]

hinges

while hinging a limb around, if I think the wood will not hold I tie the end of my rope around the limb I am cutting about 6 inches after my cut leave about 2 feet of slack and give a wrap and a half before my cut, this stops the limb from taking off ( if it breaks clear)and will still alow your rope to act as hinge wood. Once the limb is where you want it unwrap your rope from the stub and finish your tree.

Notch in the direction you want it to go, then pull on rope to move it. This is commonly done; with a second rope and the right pull you can move a branch laterally or even up to get it clear.
No limits on moving things, just time and gear to do it. "Give me a lever and a place to stand and I can move the earth." Archimedes may have been an arborist at heart.

i think that that leverage forces a spar around on a stronger hinge (with slow BackCut). The increased leverage places more power in the hinge, the speed of the BackCut determines slow-power or faster- but weaker tradeoffs that the hinge machine makes available from the increased power given(like anyt other power to speed from available power principles). A stronger hinge can give more leveraged support to keep the load up higher/ longer/ more successfully. The same mechancichs as felling, but with different angles of pull.

i think sweeping near -horizontal limbs to throw or catch(rig), is one of the most dynamic examples of hinging on a path different from gravity's pull. i think the tapered hinge, swing dutchy especially proper pivot placemeant (bottom of hinge towards gravity pull) choice, as well as this leveraging a stronger hinge to more support the load with line pull, taking that further into twisting tourquing the fibers for even more support etc. all apply to both climbing and felling.

Hinging on a different path than where gravity pulls most lessens the forcefullness of the close of the hinge, for the maximum path of gravity's pull is not followed; this even makes bucking top compressed (supported from both ends) logs easier IMLHO. In rigging it can hand laods off to the rig for less dynamic loading by moving the hitch point under the support point as much as possible; sometimes even leveraging pretightening in the line for the force at tear off of the hinge...


Orrrrr something like that......
