I have found that I use a thread stand (I use mostly cones) and wrap the thread twice around the upper arm to get a tight enough tension on the bobbin. I also have the tensioner on the bobbin winder tightened right down. I love mine. I screwed up the tension on my old Viking which I used to wind bobbins for my Bailey. It's fixed now, but I'm not going to do that again.
