I have several old singers that I have taken apart and cleaned. Now they all seem to have the same problem. I'm getting bird's nests on the back. I got one of the tension testers for the bobbin to make sure I had the lower tension adjusted correctly. No matter what I do, I keep getting bird's nests. Since this is happening with all my machines, I'm assuming I've got the same problem with all of them (Me). Now, I'm having the same problem with my Brother, which is not a vintage machine (but is one of the cheap ones). I do hold the threads when I begin sewing so it is not that. In fact, I can sew several inches before I start to have problems. My stitches look like the top tension is too loose, or the bottom too tight, but no amount of adjusting seems to help. If any of you have suggestions I would love to hear them. I've pretty much quit sewing because I'm so frustrated.
