Plating over nickel
One more thing: Often I am faced with the task of replating complicated parts over old nickel in my clock restoration work. Keys, setters, and other small complicated parts respond well to an ultrasonic cleaning, an overnight workout in the tumbler, through degreasing and cleaning after tumbling, then activation and plating. If the parts are in reasonable condition, this is a good alternative to stripping and starting over.
