That point where Gary grabbed the cut off made me cringe too when I saw that. Calculated risk or not, when you get it wrong you pay with a finger (or more). The blade was spinning down anyway, so why not step aside and wait for it till it's stopped?
I remember an incident I had when I was like 12, I was shaping a small metal plate of 5x5 cm on a bench mounted grinding wheel. I just finished it and turned the grinder off. Then I wanted to pick up the piece of metal that was still on it, but accidentally pushed it against the wheel, it got caught, together with my finger tip so that my finger tip was lodged in between the plate and the wheel. Luckily the wheel was already spinning down and instead of grinding away at my finger it came to a full stop. Got away with just some internal hemorrhaging. But I was scared sh**less by the incindent, realising what could have happened if the wheel was still turned on. Never did a silly thing with a power tool again (well, maybe once or twice [wink], but it sure made me aware of the dangers).
Yankee, your comments are uncalled for. So I'd say:
Yankee go home! I agree with uncle Sam! [poke]
(Just a tongue in cheek remark, nobody needs to go home and Sam's not my uncle, but it sounded nice. [big grin])
