I am glad I have this recorded! I had it set up the way I wanted, but while I was working away on the backstrap of the in-leaning tree, the hinge failed on the out-leaner! I did not see that because the tree I was working on blocked the view. The chain swung it over to our side of the boundary fence, and then the in-leaner dropped on top of it. You can watch both hinges fail, going sideways. Snags always have extra risks. The wood had lost some strength on these stems and I am lucky the hinge on the out-leaner held until the other one was able to go.
One of the things to do when making your falling plan is to figure out where the tree will go if the hinge fails. You can tell that within a 90 degree quadrant. That is the worst place to be during your cutting. These trees fell almost 90 degrees from where I intended because of the first hinge failure, and knowing where NOT to be turned out to be vital to me remaining vertical when it was all over.
