Question about Sewing Machines
Any suggestions how to loosen the knob to wind bobbin I can't loosen the stop motion knob on my Necchi sewing machine model 3354. I don't want the needle to go up and down while I'm threading a bobbin.
SOURCE: Stop Motion Knob
I'm sure you have a pair of Channel lock pliers around.Place a fairly thick piece of fabric around the inner knob to keep from scratching it. Grasp it with the pliers while holding the handwheel and turn it to the left. IF you can't hold the wheel to keep it from slipping, place a screwdriver or something else under the needle set screw area, turn the wheel until the set screw is resting against the set screw and then turn the inner knob with the pliers.

I had the same problem and fixed it myself. Remove the portion of the housing that coincides with the bobbin winder. You will need to remove two screws to do this--one is just to the upper left of the bobbin winder itself, and one is hidden under the handle on the left side of the machine (lift the handle, and look on the machine on the left side.) It takes some coaxing to remove the housing, but it can be done--be gentle. If you need to, remove the housing on the left side of the machine that covers the needle assembly. This will make it a bit easier, but still, be gentle.)
After removing the housing, you will see a black metal piece with a elongated slot and a screw adjacent to the bobbin winder mechanism. Unscrew the screw a turn or two, and slide the piece to the other side. Tighten gently. Turn your machine on, and move your bobbin winder back and forth and watch the screen change from bobbin winding to the main straight stitch screen. Now, do a brief Dance of Joy. I hope this helps.

Generally when the needle does not pick up the bobbin thread, it means the needle is either too far in or just plain the wrong length. YOu might want to try lowering the needle just a hair and see if that helps.

If you turn the handwheel, can you see a metal ring rotating around the outer edge of the bobbin case? If not rotating, broken gear or timing belt off.
If that ring is turning, remove the needle plate and bobbin case. As this ring now rotates, you will a finger on the ring that will pass behind the needle from right to left and it should catch the thread from the eye of the needle. If this finger, the "hook" passes above the eye, you have a timing problem.
Let me know.
