what you did not know about the Bobbin of your machine

Although nowadays the mechanisms and parts of sewing machines are increasingly standard, there may still be small differences between brands and models so that what one machine uses may not work on another. That is why - no matter how trite it may seem - always consult the operating manual of our sewing machine before experimenting with parts or accessories that do not come with it.

Machines whose bobbins have slight differences from those of other brands are: Husqvarna Viking, BabyLoock, Bernina. Most low-cost machines have standardized machine accessories, however high-end machine accessories may not be fully compatible with your inexpensive sewing machine.

1. Types of Bobbins
You will already know that some bobbins are made of plastic, while others are made of metal. There are people who prefer metal bobbins as they tend to be stronger.

In my experience, when I had Kenmore and Singer Facilita sewing machines (back in the 80s que) that came with metal bobbins, they deteriorated quickly, rusted, sometimes fell to the floor and I stepped on them and bent. which caused a thousand headaches.





Obviously there are metal bobbins of a higher quality but also quite high cost, this is the case of the bobbins of my Bernina 950 machine, they are even beautiful. They feel heavy, they are polished and of the three that came with the machine, only one is damaged, it is very crooked and I really don't remember what happened to it. They are already 30 years old with me.

Metal and plastic bobbins for sewing machines

In the first decade of 2000 when I bought the Brother LS2125 I got to know the plastic spools, since then I have tried some bought in different places or online stores and they have all worked for me in it.
I have two other sewing machines a Bernette London 5 that I use little because it sounds too much from the beginning and she came with three slightly different bobbins, hers work for my other machines but I have not yet tried other than hers.

The other machine is the Janome 311, a workhorse is the one that appears in most of my videos and the one that I use the most for my personal projects. sold by e-Bay. Now with none of these three I have tried metal bobbins and I think I will not 😜

3. Bobbin case thread tension

As if the voltage was not confusing enough, the bobbin has its own tension system, as a general recommendation the manufacturer says that it is better not to modify the original tension. As you get more experienced or have another replacement bobbin case, you might venture into altering the bobbin tension.

In projects such as sewing with elastic thread, some seamstresses recommend modifying the tension of the bobbin case, however, in my experience I have not had to resort to it, I only modify the tension in the upper thread.

4. Winding the bobbin

Most sewing machines have a built-in winding system. A good, undamaged bobbin winds evenly, just like a spool of thread. Neither end should contain more thread than the other, nor should knots be formed.

Tip: wind the bobbin at medium speed. Going too fast can stretch the thread, making the thread more susceptible to breakage, as well as deforming the appearance
