Re: Bobbin thread tension changes as the bobbin wears down? I find that I do have to adjust my bobbin as it empties. I've been sewing all my life, and doing
machine embroidery for about 18 months now, so I can make a quick adjustments, and pretty much "feel" if it's right.
I think the necessity to adjust has to do with the fact that as the bobbin empties, it has to make more rotations.
Sometimes, the bobbin case needs to be blown out with canned air a little bit.
I just started using the magna core bobbins, and they do seem better than the cardboard sided Vista bobbins I was using.
I also just swapped out my bobbin case with a new one.
Everything mechanical is going to experience wear and tear. And also, bobbin tensions, it seems to me will need to be adjusted more frequently because the bobbin is always being used, no matter what needle you're using. |
