not willing to test that theory.

I did test it and lost in a big way. I damn near lost 3 fingers! I'm
here to tell you from experience, there's no freakin' way you can pull
away fast enough. And I was just putting light pressure on top of the
board, I wans't even holding it. See my old post for a recap and a link
to some pretty pics :-)

according to that post you were pushing the board when that happened.
this thread is about going around to the back of the saw and pulling.
different animal.
No, the fingers were BEHIND the blade. No matter that his other hand
was pushing. so what. the fact is the hand behind the blade was drawn
into the blade.
Clearly you do not comprehend the mechanics of the incident.
OP was standing in front of the saw (normal position). He was pushing
a large block of wood through with one hand. He reached up and pushed
the far end of the wood DOWN past the blade. Then the kickback
occured. Regardless of how he wrote the description it is clear that
the far hand DROPPED onto the blade rather than was pulled, OR the
momentum of his pushing hand being pushed back along with his body
drew the other hand back. The wood did not pull his hand back. That
defies physics and logic.
Besides, that is NOT the operation we're discussing. We're discussing
standing behind the saw, pulling on a piece of wood. Try your own SAFE
experiment. Take a piece of wood; 1x3 would be typical for the
operation being discussed, but suit yourself. Grab it with one hand as
if you were pulling it through saw (that means no death grip) and have
SWMBO or #1 kid suddenly yank the other end (just like a kickback
would). I defy you to keep a grip, much less be pulled toward him/her.
Report the results to us. You can type them yourself.
Wrong, I was pushing down lightly with my left hand on the back of the
board behind the blade, while pushing with my right hand. The kickback
most definitely pulled my left hand back through the blade. Not down on
top. Physics and logic aside, that's what happened, and it all happened
in the blink of an eye.
