I was making up a ZCI for a 3/4” dado stack. Working in the sun and getting hot and lazy. Of course, I put a board over the ZCI and started to raise the blade through it, but being hot and tired, I only held it there by hand instead of taking the 10 steps that was required to grab a couple of clamps. You can see where this is going. When the blade came through the board, it caught it and it moved, my hand with it. A very close call that could have been a lot worse. I cannot call this an accident, it was stupidity, and something I know better than to do. I hope some good comes out of it by keeping someone else from repeating my mistake.
After a bit of cleaning and a band aid, I clamped a piece of wood over the ZCI, and put the tools away for the day. Don’t work overheated or tired, tools bite. A bit out of focus, kinda hard with only 1 hand, but you get the idea.
