While you're at it .. might try to tell this guy that his tautline is a relic of the stone age...
Actually the rip cut has plenty of uses and one of the best is in rigging applications... that said, I don't like him throwing his arm up to push every little piece over.. that is a move that he could get away with for decades, then one day when the saw isn't cutting right, it could end up in his lap.. happened to a local tree guy here, working from the bucket.. He swears it would not have happened if the saw was cutting well. over 200 stitshes to the face. Plastic surgeons did a great job and you can barely tell he had any damage..
I think this isn't the guy that I talked to, though that could be mistaken.. I love that look of puzzlement in his eye as he contemplates his next move. And the bare chested workers..... kind like COPS meets arboriculture.
and IMO, this guy is doing nothing different that 80% of the arborists out there.. What you see him doing is probably SOP for the vast majority of pros in the USA.. You all just hang around these websites and start thinking everybody has a similar knowledge and attitude regarding safety.. They don't.. and they keep getting lucky, without realizing it.. 'til one day the hammer drops..
