Right or wrong, here’s what my stumps and trees look like most of the time:
1) Cut Notch
2) Plunge out heartwood, leaving hinge on each side
3) Bore parallel to notch, leaving hinge
4) Bore from other side, making sure to overlap
5) Cut “trigger” - Inside to Outside preferred, but can be done vice versa.

Notice no heartwood fiber pulled:

Had to trim some root flare off this one too. This Red Oak was leaning slightly downhill, toward the notch. I didn’t have to steer this one much to avoid any other trees, etc. but this cutting method does well for me, even if I have to pull the tree against the lean some. But every cut has its limits and I’ve certainly found them before. Stay safe guys!
