Similar story like BenK... Recently I was felling a dry birch (about 15" diameter) for friend. He had no experience with chainsaw, so I explained him all steps and wanted to show him the safe technique. Looked at the tree, it seemed to stand straight, so we decided where we want it to fall. Then I did conventional face cut, up to 1/4 of the tree, started back cut, inserted a wedge when possible. When the hinge was about 1,5" I wanted to take the saw out of the cut and start wedging, but the tree suddenly started to fall - in the opposite direction than intended (the hinge worked well
), over the saw and wedge! Thanks God nothing happened...
Any ideas to what I did wrongly? No strong wind was blowing, the tree was dry but healthy (maybe the inner 2" rotten but not more). My only idea is that I must have misjudged the lean.
