I'm just a dumb forester; what do I know?
2 feet either side of the crown between the roof and the crown of the tree next to it. Leaned over the roof. Block face to keep it on the stump while it cleared the roof, few whacks on the wedge, no drama.
Swung this one 120 degrees away from powerlines, across a road, and away from the sidewalk into the lawn. Dutchman + siswheel, did not end up needing the wedges.
These were taken last February during storm cleanup. The forestry crew I work with got press-ganged into doing tree work within the fence. It was fun and I would do it again. I know plenty of folks who are way better with a saw than I am. I like to learn new stuff.
Here's a yard walnut I swung about 90 degrees from its lean; again, no wedges needed:
This is more typical of what I end up cutting:
It's all the same to me. Each tree is its own challenge. Figuring out the physics and making it work is fun. I've only used a rope once and that was at the insistence of the homeowner. Everything went well, and I'd do that again, too. I've had a loader bump one over because I didn't want to pound on wedges. Whatever works -- no method is the be-all-end-all.
