Bought a couple of extra long up spiral router bits for my mortising jig. Decided to try some template routing so installed the bushing and collar and bit in my M12V - a brand new one I had in a drawer so I hadn't reworked the plunge springs etc.
IAC, I had the router on the bench and was checking to be sure it wasn't rubbing on the guide collar so I pressed down on the router plate and compressed the springs while I grabbed the bit (by the business end) and started to rotate the bit between left thumb and forefinger. It was rubbing the collar so I released a wee bit of the pressure I was holding on the plate with my right hand and wham! - the strong spring load slammed the plate to the top of its travel, pushing my left hand along with it. This is the hand that was clutching bravely to the bit.
Those suckers are SHARP!
And for those who haven't tried it - getting bloodstains out of white oak is a PITA.
Walked around the shop for the rest of the day saying "Dumb!"
Moral of the story - routers can bite you even when they're not plugged in.
