i learned a long time ago from my grandpa why i barber chairs happen and how to prevent them. i stuck true to this and have never had it happen to me. i have seen it happen to other guys though. i learned it's all about the depth of you undercut and the height of your back cut. 1/3 of the tree's diameter max for the undercut and an inch or 2 above the undercut joint for the back cut. i have never had a problem doing it this way regardless of whether i'm doing cuts from both sides or not. i was out in the woods one day and there was a guy wanting to take down a tree. he had the roads blocked which was good but i could see what he was doing. he went pretty much half way through the tree for his undercut. i didn't expect anything bad to happen because i never saw it before. all i knew was that his undercut was a little crazy. he started his back cut and that thing split so fast he must have sh@#. 2 uncontrolled tree halfs falling at once would be scary. hahahahahah anyways he lived. no harm done to him luckily because he could have died. has anybody ever heard of the dutchman cut? somebody must have. i learned that years ago from my grandpa and haven't masteres it yet but getting there.
