It's a good morning in my house, I hope it is in yours! My DH got my Brother SE270D fixed/ timed ! Yea😃 ... He opened it up again and took the belt off that moves your bottom shaft. We got the needle set where it needed to be, for the shuttle to pick up the thread. He turned the lower shaft with the belt off until the shuttle hook was where it would catch the top thread. The shuttle hook catches the top thread and pulls it across your bobbin case, picking up your bobbin thread in the process. I knew he could fix it!!! The 2nd photo is showing the Cutie how I leave my cassette threaded. When I change thread color, emb or sewing, I cut the thread crossing over the top of machine & tie the new thread on. Unthread your needle & pull it through. You will have to rethread your needle by hand, but small price to pay for using your machine. Like I said before 'Get that baby out of that shed.'- while I am singing my DH praises I'll tell you he made all my thread stands too!
