I think there is a component of having the pith in the hinge.
"angiosperms (hardwoods) and gymnosperms (softwoods) build compensatory wood differently. Angiosperms produce tension wood on the upper side of a leaning stem, which contracts to pull it upright, while gymnosperms produce...
When cutting big trees, way easier to clear the wedge out of the face-cut.
I've bore-cut vertically into the center of a wedge, inserted a wedge, pounded to split the face, slid 1/2 out, then a blow on the remaining vertical side of the second 1/2 releases the second 1/2. They side down and...
The swing out station can come out to the left and the right. From the right, with the belt and covers in the way it’s not good.
From the left (pictured) it’s better than you think, because there’s only one lever to operate (as opposed to the two levers, ergo two handed operation of the Rayco)...
Beating on a horse’s grave…
I think tree shape is relevant.
On a round tree with no face, the uncut portion is a triangle. The forward point toward the lay is going to resist and the tree is going to seek the path of least resistance, one side or another. If you have ever ridden a 3 wheeler...
Re: bending vs pulling hinge, I had a bulb on that one too.
Buckin went east and Humboldted some hardwoods. Fiber pull. The more closed Humboldt pulls fiber, where as an open or vertical hinge face bends and breaks the fibers before it closes.
Usually when the two cuts are compared, they are drawn symmetrically, one up and one down.
In real life, a Humboldt tends to be less open and deeper and a conventional more vertical, open, and shallow.
Proponents of the Humboldt say that the conventional wastes wood off the butt log.
