Frank S - Your story prompts mine. In recent years everyone is giving up on corded drills and going over to cordless. So perfectly good corded drills sell for next to nothing at estate and garage sales. Often at the next garage sale or flea market space there will be a complete cordless set with aged out batteries for which there are no usable replacements available at any price. Worthless, but there maybe a $30-$40 price tag on it. Go figure.....
Some time back I bought a good sized inverter to use in my truck for various stuff I use on long camping trips. When confronted later with a $5 used 1/4" corded drill I realized the inverter would drive it. It sits behind the seat of my truck with a bag of common resharpened drills. It's been useful more than once. One of these days I'll add some hex bits and wood spade drills to the bag. 5/8 spade drill is easy to resharpen and can drill a hole in a piece of wood for an emergency repair big enough to pass a rope through.
