The satisfaction you gain when you start with a piece of worthless junk that does not work, and end up with a like new wonder machine that sews like a dream is amazing. Enjoy the adventure. I remember a particular Singer that came in. It was old, filthy, full of crud, and locked solid. But, the customer was desperate. She had just inherited this machine from her grandmother and had learned to sew on it years ago. It just had to be saved. So, it was. After a thorough cleaning, servicing, a few adjustments; the machine looked sharp and sewed like new. The thrill itself would have been worth the work, but it also helped pay the bills.
