In the beginning of the week, I posted that the bobbin "throat plate" just goes around in my FW and tonight it the first I've been able to get to it. Someone told me the "finger" needed to be put in the "notch". That appears to be the problem, but I can't get the throat plate out. I have no idea how it came out to begin with. I have never removed it. So how do I get it out to put it back in correctly??
