Singer 66 bobbin case?
I have a question about the Singer 66-13, the bobbin case rattles in my machine. I'm tinkering with it a bit, but one screw is cemented in place, which means I can't get into the case to see what is going on underneath. The bobbin case has a slight jiggle to it when it sews, which makes the machine pretty loud when I use it. Is this normal?
