I think my main point is at the end if the day technique trumps an equipment fix.... and honestly I would rather deal with a spar supported by limbs than on some jack rig that could spit out at any point when you take a limb of that changes the COG... sounds way sketchy to me... I would rather have it suspended on limbs that I can remove in a planned fashion than one questionable stable point of connection...I'm sorry, the way the question is worded is plucking at me. Neither is overly dangerous if you know what you are doing, if you haven't a clue, they are both dangerous. I just don't see why an experienced guy would ask the question, and I don't see why a newbie would ask a potentially dangerous question of a bunch of guys on line. I quit following the home owners helper thread because there are a half dozen or so guys that really know what they are doing. Then you get a guy that's only been using his Craftsman chainsaw for a month, answering potentially dangerous questions, with really stupid advice, and his advice is just as viable as the pro. The problem with asking advice here, is guys are going to answer assuming, you have equipment as good as theirs, that's as sharp as theirs, with out actually knowing the OP. If the OP posts a pic and I say, "Just make a deep notch and follow with a fast back cut." Turns out the OP has a dull MS 290 with an 18" bar, and I'm using my MS 660 with a 36" bar that I just sharpened razor sharp. Too many variables to safely give advice on line.
Case in point... cleaning up after Ike in Houston in '08 I was bucking and limbing with a trackhoe with thumbs... he lifted the trunk up so I could buck it... and happened to put a **** ton of tension on the trunk, neither one of us saw it, but when I got 2/3 of the way through it basically did a horizontal barber chair and swatted me 30' like I was a bug.... 2 busted ribs later I told him thanks but no thanks, I will buck and limb where they lie, lol
