Thanks so much for the great tutorial on cleaning the motor, it's terrific to see so many pictures included. And thank you for getting back to me about the brushes.
I haven't touched my machines since I got married, now that we've gotten past the first 20 years, we just bought a house and I'm about to have my first sewing room, once I get everything straightened away in there I figure he can play on his computer and I can play with the vintage sewing machines I've collected since we married. So it should be just a matter of cleaning and oiling I hope. I can't afford to have them all tuned up. DH bought me a treadle that definitely needs some loving care but there's no rust just accumulated dust from sitting in someone's nice dry attic for a lot of years. One of the reasons for getting the vintage machines is that you're supposed to be able to maintain them yourself pretty much (once you learn how).
