Annette, I don't understand what you are suggesting. Can you describe what you mean in more detail? In my mind, I'm thinking the thread goes from the spool over to the tension, and then under and through the discs and up to the bobbin that is being filled. I can't picture how you can get a figure 8 in there and where to put it

Thanks.

I have a Singer 15-91 and encountered this problem before and easy to correct. If i'm using taller thread cones then i'll sit my thread stand just to the left front of the machine and feed the thread through the bobbin winder thread tension disc as usual. You may find guiding the thread between your fingers (before the bobbin winder tension disc) helps. Also, using a slightly slower feed rate when winding the bobbin helps :thumbup:
Since doing this, i do not encounter any problems at all. I doubt the tension disc needs adjusting unless it's been stripped down and not properly re-set on reassembly.

I have just started working on a clone that looks exactly like yours. It’s a beauty!

Sorry Hooligan, I've been too busy to get on the board lately.

So it goes from the spool to the right of the tensioner, wraps around under the tensioner, then to the winder. So it makes an "X" where it crosses at the top of the tensioner.

Hiya, I've included a couple of images to show where i place my thread stand if using the taller cones. I also want to note that if it (machine) is set-up correctly then all you need is medium rate speed to wind the bobbin. The only other issue i've had is with inferior machined modern bobbins but does not relate to the problem you mention :thumbup:

So to get the "figure 8" or X at the top of the tensioner, the thread would go from the cone holder, across the top of the tensioner first, then underneath, then up to the bobbin. It creates a snugger fit. Maybe I'm crazy, but it's just what I've learned to do with all bobbin winder tensioners. In your picture, the thread goes from the cone holder underneath the tensioner first, then straight up to the bobbin winder.

If your bobbin is slipping while winding, sometimes you can put a shim in the center post to widen it's grip. But I can't remember if that machine has a split post, so you can do that. Mine is out in the garage at the moment.

@quiltedsunshine That is correct (works great every time). I'm not the OP, only merely trying to help with my experience with the 15-91 model :thumbup:

I am the original poster, and have not been on the Board in a while. I so appreciate everyone's help and suggestions!! Quite a few responses have been added since my last visit. This forum is the best! So much knowledge and help. I am eager to be able to sew more on this machine, and I really appreciate everyone's input. I am looking to order a thread stand today!! https://cdn.quiltingboard.com/images/smilies/smile.png

Just wanted to add: your 15 clone has the name "Universal" on the badge. It's a beautiful machine!

Don't tell anyone, but I'm a bit of a control freak. When I wind bobbins, I hold the thread as it's winding on the bobbin. I'm sort of an extra tensioning device. Usually it's because the bobbin doesn't fill evenly, so I manually guide the thread back and forth. Sometimes I just want some extra drag on it so it's as full as possible. I think it's a holdover from winding balls of yarn on my ball winder.
