Found this on YouTube.... this is why I do what I do
This guy had the face cut both wrong and with too small an angle, then cut from the back kind of randomly, and the tree started moving before a hinge was "formed" properly , and a few more things that predictably ended up like this What Hinge that was there closed and jacked on that tree, hinge too thick & strong to break, started the "shear" that ended up in a Chair. Won't happen every time, but it's not unusual to see exactly that, especially with small angles and thick hinges.

On tree's like that I plunge cut into the face cut and take about a 1/3 of the hinge away. Bore cut from the hold wood TOO the hinge. Since the tree is not moving with enough "hold" or trigger wood, I have time to form the hinge. Tree isn't moving. Even adjust the face if I needed to. Once the hinge & face cut are "right" nip the trigger and leave. The knowledge or "experience" to make this approach safe is knowing how much hinge is needed.

Looks like he cut through his hinge on the opposite side too?

I think the question now is, how much redirect can you get by adjusting the gun? I think the answer comes from experience and depends on each tree. I know I have gotten too greedy in the past and they just bust off. Gonna try the basic 3’ of lean, 3’ of gun adjust and see.

Momentum…if you can get it started in the direction you want (plus a little maybe), then maybe it will carry in that direction once the hinge breaks. Pulling with a vehicle is best for that I think.

In simple language... If you are cutting from the front of the gun, some as the angle of the "fold" is effected directly. right until your bar gets pinched or your now "Dutchman" does it's dirty deed Cutting from the back? "Chasing"? A little because the varying thickness of said hinge does effect how it folds a bit ( do your compression & tension analysis to find the fold line based on the varying thickness, and THAT is only for the first few degree's of folding. And why sit under a tree anyway? ) . and once the hinge breaks the tree just drops straight from there. Another "twist" is directed by allowing a portion of the hinge to break sooner, then using either the face cut "angle" or lean to effect a direction change as part of the hinge tears while the intact section acts like a rope or cable to get pivot, but a pretty dicey maneuver for most. Me? Why go thru all that chit. Spend the time to get the hinge right, ( bore cut with hold or trigger wood ). No rush and scramble, just get the cut right. Easiest to cut from the hold wood to the back of the hinge with the "bottom" side of the bar first then go to the other side second to finish the hinge & adjust if required the hold wood. ( Some times I "reverse" the preferred side to start the bore cut based on the tree's lean or where I think it might go if it breaks ) Then set away to a safe spot, get your self settled, evaluate what's about to happen with a clear, not rushed; mindset, figure the best place avoiding carnage for your release cut, step in snip and leave. Doing all that with a clear and calm head is really important. Especially with the trees I have where either crap is raining down, or they snap bang hit the ground before you have much time to play around. Or even worse break the hold wood before u have a chance to release the tree. Another subject.....the relationship of the hinge strength to the hold wood.... but this is getting too long.

I have literally a hundred of these small snippets where I would video either the hinge directly of something like this explaining a variation in technique.

Another leaner & using the root flare for hinge wood with a really open face cut. PROBABLY more than needed but it worked. U can see as the tree falls really how much face cut was needed as when the hinge breaks... it drops so any more face cut angle than that doesn't do much but take time and fuel. but that tree was "money" so a little more time to capture as much wood as possible is the rule for me and it does add up.

Hey Dan, nice to see you checking in.

Hey Dan, nice to see you checking in.

Thanks Jim! How have you been?

Thanks Jim! How have you been?

Doing well, just finishing up the haying season & hopefully have about a month or so of free time before harvest starts. Well, free time to do a bunch of odd jobs that need done & maybe get some saw time in.

I take it your business is keeping you jumping?

Jumping, climbing and running. Lol. I haven't worked on a saw in nearly a year, besides just routine stuff to keep them cutting.

Some disease ridden larch in amongst chestnut and oak some centres aren't good so using the root flair as holding wood too get them down the hill as most have grown with the gradient

 

[Duce]

Went as planned.

@afleetcommand how do you trim the flares off these?

I will definitely second that
