I have signed up at my LQS for "The Cleaning and Care of Your Singer Featherweight Class." It is a 4 hour class that is hands on. The FW will be disassembled, cleaned, oiled lubricated. Emphasis will be on the bobbin area showing where threads collect and the importance of cleaning the needle plate area on a regular basis. They will also teach how to give my FW a protective finish and clean up a case that has an odor. It is $55. What do you think? I bought it about 6 weeks ago and have not had it "tuned up."
I think I have attached a picture of my "Penny" named after the friend who sold it to me.
