Nope, no skinned elbows, but when I was changing out bits, one of those little stinkers bit me pretty good on the back of my hand!
I would say it was two, Herb. The first battery was a little one, and Ken changed it out when he thought it sounded like it was getting low (but I don't think it was). The second one actually stopped in the middle of a cut, resulting in Ken changing to the third. That's the funny thing about my cordless; when it's done, there's no warning. It's done, and it just STOPS. Like someone put a brake on; that's been one of the things we've had to adjust to going from corded to cordless: When you turn off a cordless, the turning stops on a dime. When turning off a corded machine, it stops gradually.
