My sewing machine was making a noise that sounded almost like a hen getting ready to lay an egg, so it was a bit alarming. After oiling everything and making sure there were no threads or lint, I thought of maybe putting in a bobbincase [metal] from another machine. As I was examining the bobbincase, I noticed that inside the tube that goes over the spindle was looking a little rusty, so I put some sewing machine oil on a q-tip, cleaned inside the tube, replaced the bobbin and bobbincase and now the machine purrs like a kitten. Weird. Don't know if the touchtronic has a metal bobbincase or not, though.
