I know you're supposed to let the router come to a stop before removing it from the workpiece, but I'm trying to understand how this happened? Did you nick the workpiece as you pulled it out or something?
You know, I was really carefull (like paranoid carefull for good reason) about pulling it out. It was out of the workpiece for about 3 seconds and I was about to turn it off. Then it happened. All I can guess is that the collet loosened up and finally gave way once it had no resistance.
The more I think about it the more I just want to put it behind me because it's kinda embarrassing and insulting at the same time.
Scared the bejesus out of me and I always prided myself on my safety habits.
My dad painted on the wall of his workshop (when I was 6 or so) "You can't grow back your finger, you can't grow back your arm, remember if you saw them off you've done eternal harm."
I'll never forget it, and now it's that much more pertinent.
