I purchased a TOWA (bobbin case tension gauge) last year and am trying to figure out how to use it. I am trying to set the tension on my longarm (Tin Lizzie). Oh, if it matters, I have the TOWA TM-3 model.
I was able to get the bobbin in correctly, but I don't know what the tension strength should be. It's currently at 200. Is it too tight? too loose? just right?
