    Rigging Mid-line

    Bouquets Mr. Tom Dunlap would say/preach. Can also try small prussics if need spaced Orchestrated correctly, could have the terminal Running Bowl as stated, cut first for force, then next in line held only by force of tension line from each side to Half Hitch in-between. Rope is fantastic...

    Chain does not go in bar

    Great! i have kinda reshaped thin cheap linoleum knife to clean / take back to spec groove by pulling around laser nose down each side or away from sprocket nose each side and sharpened tip in knife to clean like entrance port each side. Kinda re spec any time take apart. Simply give system...

    Chain does not go in bar

    Breaking problem into parts does a new or section of old links. This could be scuffed or bent drive links into bar from that side of this marriage and/or narrowed or bent bar side of marriage. . The work is so hard, everything without work must be silky smooth riding on thin film of oil. Arcs...

    Can you pull a tree with 2 ropes tied together?

    Round Sheet as stated perhaps slipped. If one rope smaller / tighter, that must be the locking hitch side especially single sheet. The larger/'fluffier' side of Sheet Bend the more passive bight; just like smaller cord for friction hitch grip on larger host. . Echoing Del_ to on 'parts...

    New to climbing, calling on experts: double security system

    You can make an adjustable lanyard by using a Friction Hitch, usually to side Ds. But with steel core probably want gibbs type mechanical grab/pinch THRU to steel core. FYI the cam arc is Fibonacci/Nautilus shell arc to hit the magic geometry required to hit the magic geometry to work...

    Safety one-liners

    2is1 and 1isNone. It is not the fall, but the sudden stop. Learn from horrifying statistics, instead of being one is best. Slow is steady and steady is fast (rescue version of tortoise and hare) Average chainsaw emergency room visit: 110+ stitches (we've all probably heard some lower numbers...

    Does a prussik have to be thinner than the rope its round?

    Does a prussik have to be thinner than the rope its around? >>IF is closed friction hitch of 2 legs of loaded support to saddle as Prussic, not so much single loaded leg 'open' friction hitch such as Blake's/Proh-grip. . . Blake's real and faux(foe) 'sui-slide': . A> When working with rigid...

    Concept: Center of Gravity Is King by Force, in Domain of Weightless Wood

    This is great, for truly i was not born knowing these things that i remember. Many times reading, many places here and elsewheres i find myself wondering if everyone is on the same page of this deeply pivotal concept. One that i had to keep bringing self back to, to get here; but now live...

    Wrong direction fall - feedback welcome

    If fold line(front of hinge span) and CoG (Center of Gravity)are at same point/unchanged in scenario: Tree load pulls forward at same force(same weight, height, angle to same pivot), so forces same resistance against fall forward per thickness of hinge from target. Central machine point pivot...

    FALLING VS. FELLING

    We jest call ya often then. . To fell a tree is an action against the tree that itself falls. Whether say feller or faller is purely semantics of perspective per the action given or returned ; like as input given to vs. output achieved from the event by the chess player, gentlemens. . But, ain't...

    Concept: Center of Gravity Is King by Force, in Domain of Weightless Wood

    In rigid forms the combined/net average expression of distributions of mechanicals of weight, angle and distance to a single point is the Center of Gravity alias CoG. To model, calculate etc. can use that CoG point xForce to show how to handle, what to expect. This is true in all things, as very...

    Rigging equipment to direct the falling of trees while thinning woodlot.

    Throw bags and lines are cheap, but in a pinch have put dirt in a mechanics red rag and used paracord. >>Want soft fill so deforms and slides into target, not bounces away and light rope that does not catch as try to get bag to slide to ground. But really, throwbag and line are about the...

    Tree ID in North Florida

    To me, just looking at bark is a fast growing, softer and lighter wood of low btu value, junkier end of oak or close to oak spectrum. More towards Water Oak, than Live Oak in that scale/range.. . Live Oak is my highest oak benchmark of expressing most greatest values of many components. All...

    Aboricultural learning: post your references here

    Excellent idea. Classically Keslick's Treedictionary is chock full of stuff.

    Falling slight leaner with a plain old bottle jack?

    Undermine Center of Gravity more with a bit deeper face cut, to essentially increase lean forward to put a few more points on your side; and pull from high, rigid, balanced pull position. Wedge kinda as backup against sit down back. If some sideLean, keep hinge more in widest part of tree across...

    rope

    yo Bro! Utility class, deceptively simple, almost trick from slipped 8 +1move. Originally started Quick8 w/8 as to make parent HFP8, then lace tail opposite way thru than HFP8. Adaptation here amounts to same, just start with slipped8. >>and flip tail in loop opposite side of Standing Part/DONE...

    rope

    At IGKT forum last November knot guru Dan Lehman has simply reversed the tuckings thru fig8 to opposite direction for a quicker, and sleeker adjustable terminal/ending eye on rope like Bowline. From a very familiar figure8/slipped +1 tuck is DONE/sweeeeeet! Dan Lehman has defined points and...
