SOURCE: Winding the Bobbin

If you have a top winding bobbin on the right hand side it may be that the winder is seizing up, you must put a drop of oil now and again down the spindle otherwise it goes dry very quickly at high speed.

Wind the Bobbin
For the usual jobs, it is the best to use a medium sized thread.
2. Disengage the flywheel by unscrewing the coupling knob as far as it will go.

3. Place the bobbin on the bobbin winder, and push the bobbin winder to the right.

4. Pull out one of the spool pins and place the spool of thread on it.

5. Pass the thread through the bobbin winder tension discs, as indicated.

6. Wind the end of the thread around the bobbin by hand, in the direction indicated.

7. Wind the bobbin, at a medium speed by pressing lightly with a finger on the spool so as to stretch the thread better and thus fill the bobbin to a maximum. The full bobbin stops automatically.

8. Re-engage the flywheel by tightening the coupling knob.

9. Cut the thread and remove the bobbin from the bobbin winder by pushing the latter to the left.

On the right side of the machine there is a large knob at the top. Pull that out and you can wind your bobbin. Don't forget to push it back in so you can sew :)

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!

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
