How to Fix Problems Caused by Shuttle Hook Timing in a Sewing Machine
Set the shuttle hook timing of the sewing machine in such a way that the hook of the shuttle can properly catch the thread from the needle and form a correct loop by joining it with the thread filled in the bobbin inside the bobbin case attached to the shuttle. By setting it this way, problems caused by shuttle timing such as bobbin thread not coming up, loop not forming, stitches skipping, and sewing not happening at all can be resolved.
