Good pix, Ray.
May I respectfully give you some loggers advice.
Don't kneel when falling a tree or even a spar.
If things go to hell you've no way to escape ( Unless you are Gary!)
The closest I've ever come to losing an apprentice was in a situation like the one in your picture.
Doing clean up after a major storm ( Actually THE major storm 1999 december, known here as "The storm of the century")
A spruce had it's top ripped off about 15 feet up, so Caspar goes and fells the remaining spar.
I'd already been berating him about how those can jump about when they hit something, and that he should not be standing around looking when they went over.
Get the hell out of there!
He felled it, stood around too long, and when it hit a hidden stump and rebounded, he got caught by some brambles and couldn't get away.
Damned thing jumped about 10 feet and just brushed by him as it came down. I honestly thought I'd lost him.
It is one movie I can still see in my mind.
So every time I see someone kneeling while felling a spar, it triggers that.
So,here goes:
Even with just a spar, make sure you have cleared a way to escape, and stand up while felling it.
