Just so happens I recently built a giant Christmas tree stand for practicing Humboldts while cutting up palm.I think some slow-motion video is in order.
I'd aim for thin/ very thin hinges when having multiple, especially the rearmost hinge(s).
If you weld up a log holder, you could do some short sections of log with a slow pull from an MA system or winch.
The one effect that I won’t have is weight of the tree crushing the hinge.
The front of the hinge has to compress and the rear stretch. Can’t do much to make the rear stretch, so making room for compression if probably the way. Wood is less likely to break if it can deform into a kerf or something I think.
