wow. I just can't imagine having a ton of thread in the bobbin area. I am always taking that part apart and redoing it for my mom or SIL. I am hoping to have the machine working either till I can get mine fixed or get a new one. I wish there was a magic machine fairy that can wave her magic wand over the machine once every 10 years and make it run better than new for another 10 years. I am thinking about getting my mom a new bobbin metal thingy for her machine because I am getting tired of having to constantly go in and tighten the little bugger.
