I had an interesting problem with my sewing machine. The stitches were wobbley!!! I'd never had this problem before. I threaded and rethreaded and still had the problem. If I hadn't just had it in the shop, I might've thought I needed to have it cleaned. Then I noticed something!!! The BOBBIN was wobbling in the casement! I took it out and compared it to other bobbins and it was about 1/16th smaller!!!!! I tossed it, put in a new bobbin and VOILA -- all is okay!

Thought this might help you.

Very interesting.

Thank you for letting us know about this :D:D:D

Did a similar thing a few years ago.... machine went wacky, later opened up cleaned out, for some reacon tried a different bobbin. Boinggggg then it worked. :)

Thank you so much for finding the solution to the problem I have had in the past with my 'old' machine. (It is now sitting on the shelf, until I can deal with it.) Meanwhile, my hubby bought me a more advanced (not the best) machine, that I am having a blast using, as it does not 'wobble'. I didn't know how to describe what it was doing. :thumbup:

amandasgramma...what kind of machine do you have?

I have a Janome Jem Platinum 760. I LOVE this machine. I believe the other bobbin was a generic or was for my other machine.

I have a Janome and had the same problem after I had it cleaned. I did a lot of stuff, then finaly figured out that it came back from the shop with a bobbin with a flat top and I had been using ones with curved tops. I used them just fine before I took it in, but will only use flat topped ones now. Anyone need about 3 dozen curved top bobbins, mostly with a goodly amount of thread on them?

I just got a new machine the other day, and the owner's manual actually had a picture of the bobbin and showed an other one next to it. I will have to keep the bobbins separate from each other. Don't want to wreck the new baby.

Do ya think the companies could stick with the same bobbin??? I completely understand that all different brands will have their own, but gee couldn't Pfaff 7570 use the same bobbin as the Creative Vision???? Not sure how often this type of change ocurrs, but it is just plain annoying.

Ok, feeling better now.

I just got a used Bernina 180 and I understand that this Bernina takes different bobbins than all other Bernina's. Go figure. :roll:

Dee, thanks for sharing this with everyone. I have a Platinum 760 also and will definitely keep that in mind. :thumbup:

Never though of that before , thanks for the tip :thumbup:

I have a Viking and it takes the green bobbins that are a little bigger than standard. It dosnt like smaller bobbins but sometimes they work anyway. I had bought some prewound that I wanted to use up.

I had not originally realized that the plastic bobbins were not exactly the same size as the metal ones and that the ones with lots of holes were different as well as the ones that are really flat.

Can sure mess up the quality of your stitch if you don't use the one meant for your machine, as I learned the hard way!

I think it is just a way to make more money!
like a car and oil and air filters- they all take a different one!

And how about those DADGUM debit/credit card things at the checkout counter??? Not a ONE is the same!!!!:shock:

years ago, many moons I treated my self to a Viking that was pretty and had lots of stitches. At that time that was my creteria. So about a week or so after I had it, and it was a weekend, I decided to load a couple of bobbins to have them already filled, locked and loaded... so to speak. Well the very first one just zipped right along faster then the speed of light. Wow, I thought, this is going to be a piece of cake. WRONG... I could not get the bobbin off. Even manually unwinding it somewhat, that sucker was not coming off. Well I am franic.. called around to several Viking dealerships, but on this side of the line, Eastern time, everything was closed so I started calling over to the set of time frames and I finally reached this wonderful man who listened to me. When I finished my pity party he said.."was your bobbin winding rather quickly?" and I said yes and I just so pleased at it's performance. "Well, he said, what you have done and many others have done it is.. plastic can be tempermental. And that if you wind that plastic bobbin way to fast it will actually cause the plastic bobbin to contract or get squeezed as tight as it can get on the little rod that it's spinning on. So he then told me that I would have to unwind the entire bobbin until I could get it off and then look at it next to a new one. And sure enough you could see where the plastic has literally molded itself out of it's original shape. My Pfaff uses plastic and I set my speed under half when ever I am winding the bobbins. Just a comment.
hugs, Blue

Wow, Blue...That's something I hadn't heard of but makes PERFECT sense!! And yes, I probably did it at top speed!!! thanks for the info!

I so hope it was. Believe I am not at the level that so many others are, but when it comes to messing something up without trying, my name is at the top of the list.

I am serious, I cut my speed back to under 50% when I am winding the plastic bobbins for my Pfaff....

Wow, I would have never thought of that. Thanks for the info.

You took the words out of my mouth! I think they use different style bobbins, so that we will buy more.
