"Those Fantastic Featherweights" is a two disc set. Disc one teaches you the history of the Featherweight, tool requirements, and step-by-step maintenance instructions for the 221, plus a separate section for "the white machine" and the 222. Disc two goes beyond routine maintenance and shows the problems that may occur with your Featherweight and how to fix them. Dave covers the operation of your machine, electrical considerations, motor belt adjustment and replacement, machine timing, and many other subjects. Plus, Disc Two contains the added bonus of a special section on the Model 301 slant needle which Dave sometimes calls "The Featherweight on steroids".
