    Question M class bobbin warpage

    I have quilted several quilts now and on three of these quilts I continuously had problems with tension. After running several bobbins on the same quilt top, those bobbins ran out and I had to wind more. This one bobbin I have does not wind all the way and will start and stop winding. Then using this bobbin with the very same thread, pattern, and cloth it creates looseness in spots on the top and loop-de-loops on the back in spots. Any you longarmers had a warped m class bobbin? I suppose it can happen as it is twice the size of a regular bobbin right?

    Have you checked your bobbin tension?
    I am sure the M class could warp or be off round.

    Yes I do have a towa gauge and this seems fine when pulling the thread. You only pull off so much, so I am assuming it is not round and therfore can have intermitten problems, yes?

    Yes, it is possible for them to warp. I have tossed a few over the years that just didn't seem to work right. Definitely if it starts and stops wile winding, I personally would not use it.

    I was told when I bought mine that since they’re aluminum they could bend out of shape if dropped.

    I use the E-Z Wind slotted M bobbins, which I order from Handi Quilter. They are aluminum & come in a pkg. of 8. I have not had the problem you're describing. Did you try adjusting the tension on the bobbin winder? Another thing that really helps is using a net around your thread cone. I bought a pkg. of 12 last year. You can switch them from cone to cone. My LA is the Baby Lock Tiara II, which is a table model.

    I have aluminum bobbins, steel ones and prewound bobbins. They all perform equally well. I work in my basement and if I drop a bobbin, or more likely my bobbin case, I fear it/they could get damaged. But so far so good.

    Bobbins and their cases can be damaged, and we all can drop things! When you put it in the case with the bobbin face up, if it looks like it is not seated correctly in the center or shows an area which is slightly dented in (check both sides), I'd toss it. Having said that, check your case as well. I keep a new case around at all times and use it as one of my things to check if my longarm seems to be acting up. Could be inconsistent winding of the bobbin as well, so it might be a tension problem during quilting. Good luck, I know it can be frustrating. Would love to know what you found was the problem and how you found it. It would help us all.

    Funny thing about bobbins- it's hard to tell visually if the bobbin is the problem. Bobbins don't spin at high speed so it's harder to diagnose why they are a cause of problems. When you have the bobbin and case in your hand all might look well until you plug it into the hook. If you have one bobbin that just doesn't do it, and others will- take a hammer to it.
