I'll add a disclaimer before I get started: I'm looking for thoughts as to how something could be accomplished. I am not of a skill level I would feel comfortable doing it myself, so I won't be doing it myself right now. My folks have some rural property that I help out with when I can. After a bad wind storm we had a big oak fall over and wedge a fork onto another tall oak. As a result it's leaning at a good 45 degrees and wedged in pretty good. The tree is probably a good 30-40 feet long and maybe 24" in diameter so we're talking a lot of wood and weight. Having looked at it I'd say there are a few possible solutions. 1.) Climb up the living vertical tree and cut the small fork piece (maybe 8" diameter) from above and let the dead tree fall. Possible drawbacks are swaying live tree sending the cutter flying. 2.) Perform an undercut halfway along the leaning tree and anchor the bottom half to make sure it doesn't roll back onto the feller and hope the fork half falls far enough down to fall away from the wedged tree. 3.) Cut the living vertical tree down and back away to a spot where any rolling tree would be blocked by something else. So which of these seems the most likely option? Is there something else I'm missing as an option? Again just looking for thoughts as to how a pro might do it. Also MODS - if this is in the wrong spot please feel free to delete and/or move.
