What I am trying to do is shred a few limbs from
time to time. I have used it and if I was cautious with the feed speed, it
worked fine.

If we were going to feed 6" logs rapidly into several saws, you are correct
that we would need a lot of power. To avoid bogging the saws, we will have
to control how fast the branch feeds into the saws.

You are correct that we must align the table so that all of the contact of
the branch into the saw is at the middle or above. I have had no trouble
with it kicking back. Still, I think standing to the side, so that your
body is not in front of the blades, is a good idea.

One tooth will not stop us. Two or more together will and you are correct,
it will be a pain to disassemble the stack.
