I posted a story and video yesterday in which I tried to recreate a kickback on a table saw. I did get the kickback but even with all of the planning and knowing what was about to happen I very nearly got hurt. the video shows very clearly the speed and power of this type of event and if I had not seen it myself (later) I would have never believed how my hand was sucked toward the blade. In the last 13 hours or so I have gotten over 200 emails from people going to their shops to reinstall their splitters or blade guards because of how scary this footage is. No blood or anything (thankfully) but scary nonetheless.
