Thanks Kenny. The guy's no guru but I give him credit for applying the engineering to the videos. Unfortunately, he didn't know about the quest for the sword in the stone and only made his videos for basic information. He's clearly new to arborist work (don't watch him climb). Best...

Bit of spare time. Found it. edit - oops, that was the wrong one, though worth a watch for the basics. This was the video: Nope. Third time's the charm:

Marc, you are an edumacated dude. :) You should try to find the engineer video with the stress distribution diagram in the stem, just like a school assignment. He portrayed it as linear variation across the trunk width; probably correct if you reason it out. Real nerd stuff, but that's how it...

I've never considered before that deep side cuts would focus the forces into the hinge perhaps to induce hinge fiber failure first, whereas a stronger wider hinge can transmit more (enough) force up the tree column to induce shear failure (barber chair split). If I understood it correctly. You...

General answer -not expert- Balancing a few factors placement of hinge pivot - gives 2/3 of trunk width as wedges lever arm - to not tensile pop the hinge fibres when wedging - not a Reg over center magic cut that tips on it's own, presumed not back leaning, for vertical spar - place...
