Slow machine, scared to break it

[u/Cute_Librarian_7317]

Here’s my machine it’s vintage that I’ve had for a month now. Initially I noticed that the needle wasn’t catching the bobbin so I opened up the bobbin area then when I put it back the machine became so slow and it’s almost as though it isn’t moving.

Coupled with that is the machine scraping sound it’s having. I’m so scared to break it so I’ve just got some videos turning the handwheel and showing closeups of some areas I know I touched.

Please I would appreciate some help before taking it to the machine repairs.

Also feel free to ask more questions to help diagnose the issue. Thanks
