Hi Everybody. I am having a problem with my longest owned and most used machine. I have a Bernina Record 830 and have used it constantly (no sitting up...) for the past 25+ years. Lately I have a tension problem I can't seem to get to the bottom of. The top tension is tight, no matter what I do. The machine is kept oiled and the lint cleaned out. I have cleaned real well between and around the tension disc plates. I changed the needle. I have the bobbin set kind of tight to help pull the top thread down, and the top tension is set way too loose, but still I get tight top tension. There just isn't all that much to the top tension and threading and still I can't get it to have an acceptable tension! Any ideas? Could the tension discs be bent if the machine has not undergone any trauma and been used continually for this long? I know this machine like the back of my hand-- it's been my main workhorse-- but I can't figure this out.
Thanks for your thoughts!
