Perhaps this photo will simplify the ultimate question: In this photo, which show the bobbin business (taken off the machine, and with the bobbin next to it), should it all behave as thought it were one solid piece, or should there be freedom of movement amongst any of its components?
Currently, there is no freedom of movement; it behaves as one piece, made up of one main part with two slightly springy brackety bits (with the thread - grabbing hook/s) on them. There are no stray bits of thread or debris anywhere that I can find.
If you tell me that it ought to behave as one piece, that might help me try to troubleshoot elsewhere. Or, if indeed things here are supposed to move freely within this one piece, this tells me that something is still awry.
Thank you!
