I don't, but I'm not sure if that answers your question. I've never had
any indication that it was about to take off, but I know just because it
hasn't happened doesn't mean it can't happen.

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.
