IF you did it wrong?
It’s not that complicated. Especially when you go with the slight natural lean/weight of a just-off plumb tree. This is ALWAYS preferable, even by an expert.
Stand back, have a look from some different directions. Hang your hatchet if need be to verify plumb.
Have two clear escape routes planned.
Make your notch about 1/3 tree depth or so. Open humbolt is safest. Your back cut about 1 1/2” above your horizontal notch. All cuts level ( this is where sloppiness generally happens).
Don’t cut off your holding wood. Listen to and watch the tree as your back cut proceeds. When your backcut is a couple of inches away and above and parallel to the root of your notch slow down a bit on the cut. The tree should start to move in the intended direction. Move well away from the stump at a 45 on one of your escape trails. Watch for falling branches from your tree and others. Voila.
There are about a million YouTube videos on falling.
Hotsaws101, Buckin Billy, and several others are good resources.
Also, the Worksafe BCvideos are another good resource. Watch them all, what the heck!
Your chain is dull too. Never good to fall ANYTHING with a dull chain.
Your saw has sights. Use them.
It’s hard to imagine that you have a bunch of saws and have never dropped a tree.
That is an easy tree. You gotta get GOOD at those EVERY time before you attempt anything remotely fancy. You could drop that tree pretty quick with a 16” bar..
And it IS refreshing to see that you are comfortable showing a mistake.
Anyway, we have all done stupid stuff, or stuff that doesn’t work out as planned (one of the reasons for the escape routes). The nature of trees is that each one is different. This makes it potentially complicated.
watch some videos and read some stuff. The information in any reasonably modern chainsaw owner’s manual is a wealth of information...
Be mindful of the wind...
