AlZilla Posted November 11, 2024 Report Posted November 11, 2024 Does anyone have the actual bobbin tension spec for the 111W series machines? In my case, 111W153 and 111W151. AndyTube cites a spec for domestics of around 25 grams and apparently got it from an adjusters manual or somewhere official. I've been setting all domestics I work on at just under an ounce. I like repeatability. I have a 151 that's way too tight. I'm going to set it around an ounce and start from there, unless someone has the actual number. I looked in all the pdf manuals I have and don't see an actual number. Thanks!

Members Constabulary Posted November 11, 2024 Members Report Posted November 11, 2024 (edited) I never needed any weights for adjusting tension and afaik there are no "official" weights specs cause tension depends on material / needle / thread thickness and how tight you want the stitch. So it basically it is playing with the top and bottom tension until you have achieved what you need. I know there are "science folks" who need numbers for everything but I actually never needed that - no matter what machine I used..
