Jrue Posted December 7, 2015 Report Share Posted December 7, 2015 Brand new to my new Millie. Took the paper bobbin out & put magnetic one in. Bobbin house would not slide down the thread like it did with paper bobbin. I did remove the check spring as instructed. How do I determine correct bobbin tension with magnetic bobbins?
