Use Old Phonograph as Grindstone
OLD phonographs can be made to do double duty by changing the turntable into a novel grindstone for sharpening knives, chisels and other small cutting tools.This home-made sharpener is rigged up by cutting a piece of emery cloth of the circumference of the turn-table and slipping it over the revolving axis. When the motor is started, emery wheel turns.
