Bobbin

[maradams]

Do I take out the spring in the bobbin case when I am using a magnetic bobbin?  Is there any other time when I would leave out the spring?  How often do I need to change the bobbin spring in the case?

Yes take out the backlash spring when using magnetic bobbins.  When you put in a standard bobbin you will notice it sits a little proud of the case. Over time the spring will get a little flattened and the tangs can be bent to maintain the proper adjustment. The spring should last almost forever but keep one or two spares for when a spring goes flying across the room and you can’t find it.  I used to have a couple of bobbin cases one with the spring for regular bobbins and one without for magnetic bobbins.
