I just put a brad (proud about 1/2") in the back of my insert. Hopefully if
it (the insert) gets caught by the blade, rather than becoming a projectile,
the brad will keep it seated and the blade will just cut the wood. Might
not be needed, but what's a brad cost

The insert that came with the saw has a clip at the back and a screw at
the
front.
Does a zero clearance insert need those also?

I made mine out of 3/4" stock cause that is what I had and I can't imagine
how it could move except straight up, but I know a 3450 rpm saw blade can
do
amazing things.
