Hey Al, Your videos are great and a huge help . I’m hoping you can help me. It has to do with the hook and needle timing on on cobra class 4. I have a techsew 5100 and it sews fine but even with adjustments you suggest the needle comes down to early and just misses the top of the bobbin and comes down near that little ledge after the bobbin . But the needle and hook line up perfectly at proper timing. I’m at a loss as it sews fine just doesn’t look like any other timing I’ve seen?? Thanks for any help you can give and all the help you have provided already! Paul
