There is a book written by Dave McCallum called "The Featherweight and I" that has all the information you will need to take care of and repair and clean your featherweight. It is a life saver. It was so successful he followed it up with videos he titled "Those Fantastic Featherweights." It is expensive because there are 45 videos covering most everything you will ever need to know. I wouldn't be without either one! Carol
