Brother CS-80 Sewing Machine Bobbin Rewind

SOURCE: Sewing Machine CS-8060

I do have the very same problem! I took my bobbin case out and took a good look at it, turns out right below the plastic hook part, the plastic was cracked off (probably due to thread jamming). Turns out I need a new internal bobbin case, which range in price from $35-$50 from what I researched. I had no luck with local sewing centers on finding the part.
That may (or not) be your issue as well. Good luck, and I hope this your issue is simple fix. A little tune up after might be needed, HAPPY SEWING!! ~Kelly J~

SOURCE: Can't wind the bobbin

Hi again,

Well we finally downloaded a service manual that cost a few bucks, then finished getting the machine apart, then found a small rubber O-ring that had obviously gotten hot when spinning after the tangling of the thread on the bobbin stem. You could see where the heat had melted tiny teeth marks in the ring and it was stretched out of shape. It and yours too will need to be replaced.

If you or someone you know is mechanically inclined, you will need to take five screws out of the back including a hard to find one under the foot raising lever (lower the foot), then one form the front that is under the thread cartridge, and you will have to remove the bobbin winding plate cover which is held by one small screw, and then remove a small screw from the support bar.

Good luck!

SOURCE: I need to rewind a new bobbin

My SE-270D bobbin winder is located on the top of the machine to the far right. From the picture of your machine it looks to be in the same place. The larger spindle is for the spool of thread and the shorter spindle is for the bobbin.
You need to wnd the thread around the bobbin a few times just to make sure it is started properly, and then move the bobbin either forward or backward to engage. (It's different on some machines.) You may also have to move the outer edge of the machine wheel (the large wheel on the outside right) to keep the needle from moving up and down while the bobbin is filling. When the bobbin is full the machine should shut off by itself.
Then you will have to re-tighten the machine wheel to engage the needle.
Hope this helps.

the rubber ring on the bobbin winder has probably gone bad which would mean replacing it but you can buy a portable bobbin winder called a sidewinder for around 20.00

Most machines you slide the bobbin winder to the right to wind and then back to the left when your done to remove. Just making sure.... you did move it back to the left?
