I noticed yesterday that the screw behind the tension screw on my Baby Lock Crown Jewel longarm bobbin case has come out. This is the same machine as the HQ Avante. It still sews well. I have searched everywhere even with a magnet and then called the dealer who said you have to buy a whole new bobbin case for $130! She tried a screw from an inexpensive bobbin case in her shop and said that the threads on the screw did not match.
Does anyone have any ideas of where I could find such a screw? The company apparantly does not sell just one screw. And they want you to go through a dealer.
