How to wind the bobbin on a 3577 necchi - Sewing Machines

Is the bobbin wheel actually turning? If so, the bobbin winder is still activated. Have you tried turning the inner wheel on the handwheel to de-activate the bobbin (see video)?

If that doesn't help, you may need to take the machine for service.

How to Thread Necchi Sewing Machine

Try putting a small drop of oil on the the metal shaft of the bobbin winder if it is not moving freely. The grinding noise implicates the winder tire may be ground from the locked winder shaft. The needle not disengaging requires oil in the shaft bushing. On this machine it appears you would have to remove the covers to access the appropriate areas.

Actually, $10 for a manual is probably a valuable investment. It will not only help you with threading & winding the bobbin but also with maintenance and care of your machine and as well as how to use your machine. Similar brand machines thread and wind the bobbin in the same manner. So, even finding a similar Necchi and the bobbin winding method should be helpful.

You didn't provide the brand name of the machine. I was unable to locate any information as to a Necchi 930, so I'm assuming it is a Bernina 930 Record. If so, you can download a free manual here:

Here is a YouTube video showing how to wind a bobbin on a Bernina (newer than a 930), but still somewhat similar. The only thing I would recommend is, do not wind the bobbin as fast as she does in the video--sometimes that will cause the thread to stretch while winding.

Or stop by the local fabric store (or even Amazon online) and pick up a standalone bobbin winder for about $25 US. You can wind all your bobbins on the little unit and not subject your machine to additional wear and tear.

Its been idle for too long and needs a good service. Try and trickle some oil behind the stop motion wheel. But what it actually needs is to have the wheel removed and then apply oil to the shaft. Careful when you start again as oil will fly out from the wheel so mind your drapes and wall decor.
