Needs a new drive belt. Really. The belt is what keeps the machine in place when the lid is closed. Without the belt the machine falls out when you try to close the case. Shouldn’t be so hard to take care of, especially if you live in Portland.
I actually learned to sew on a pedal sewing machine somewhat like this when I was in first grade; it was my grandmother’s first machine and hard to get in trouble with as a new sewer. It’s good to give kids access to machines they can actually understand the inner workings of–helps them build models about how the world works.
