The purple dot represents the point of failure. The red dots were where the blocks were placed. Probably could've done a better job spreading the load through the canopy. Maybe even a third block depending on the cut
He placed two blocks on a codominate stem and the lead with the hypoxolyn canker failed at the canker. Not a large piece, but a trivial amount of dynamic load
He had two blocks in the tree, in adjacent leads, to dissipate the load. The failure occurred next to the bucket in a patch of hypoxolyn canker. Piece wasn't large although a small amount of dynamic loading took place
Sorry. Hypoxylon canker on American beech may have comprised the structural integrity of the lead in question. Two arborist blocks were placed in adjacent leads to dissipate the load.
I'm kinda sorry to see the lack of support. I have been in the biz for 21 yrs now. Resources are tight with 7 kids, but anything I can do. Hang in there brother
