I believe I have calculated it out properly, that the teeth at the outside edge of a 12” table saw blade is rotating at a speed of 123 MPH. So when a 1” x 1” x 2-1/2” piece of segmented bowl hit me in the upper arm, before imbedding itself into the hardboard masonite wall behind me, how much did my arm slow it down?

30% ? Do I win anything? I lost the vision in my right eye back in 1976 when the end of a 2×4 hit me in the brow. The force of the impact, severed my optic nerve. It only takes a split second for it all to go to pieces. Glad you are okay.

Precisely why I have migrated over to hand tools.
jaykaypur - sorry to hear the story about your eye. Vision is such a precious thing that we all take for granted.
lizardhead – the important thing is-are you OK?

When I first started using a table saw (I was using it improperly), and I had a 2×4 piece “crawl” up my arm and hit me square in the chest, leaving a nice bruise. Three things resulted from that incident: 1) I went and took classes on how to properly use woodworking power tools; 2) I bought a full face shield that I use when table sawing; 3) as a result of #1, the instructor (and very professional woodworker) showed us his partially-severed finger, so I sold my existing table saw and bought a sawstop. I really am glad you’re o.k. I saved my 2×4 piece as a reminder.

Hope you’re OK! I guess when dealing with segmented bowls, you need full body armor!

Even with caution accidents can happen, we learn from them and move on. I am getting older now and think moe about what if’s. If I could afford a SawStop, I would purchase one, just for that reason alone
