Of course I didn't see exactly what happened, but based on the ZCI damage, I think the board lifted at the back and was then promptly fired, angled down into the ZCI and blew the hole in it.
Hard for me to imagine it raising off the table as it was held down with featherboards on the fence-but its clear SOMETHING happened
You see it actually damaged the end of my pusher as well.
Anyways-the new project was figuring out how to make a new insert on my own once I realized a SS replacement would be $20 and some days.
New insert was made with 1/4 Maple ply and seems to do a pretty good job.
Next steps: Buy one of those GRR-Rippers and make some kind of fence extension that doesn't leave me in tight spaces between the fence and the blade. That always makes me feel less comfortable on a cut.
How narrow? Very narrow against the fence is not the way to do it. That could cause what you experienced.

The temptation when cutting thin strips to just set the fence the desired distance from the blade and start cutting strips is always there...but...even though it means moving the fence before every cut, a jig like this one is the safer but slower way to do it. Plans for shop-made versions can be found on line.
