Land designs:My first go at using a felling wedge to cut down a tree with a chainsaw. In the video I show the use of a Chainmeister bar clamp to sharpen a chainsaw. This video is not a tutorial.
Forestworkers:From what I learned so far, your hinge should be about 10% the diameter of the tree you're felling I still am conservative when doing my back cut though.
More practice always helps Using the wedges to do the final push to fell the tree is one of the safest bets you can do The hinge is steering the tree as it comes down. the tree will follow the path of least resistance so if your hinge is a lil thinner on one side, the tree will turn a lil towards the thinner side of the hinge
