Sonata -1 machine fixed-I did it!!!!
Hello,
Well I have fixed one of the 2 Sonata 6610 machines that I had posted about before. After several well intended people told me to forget trying to fix it, I decided to try myself. I am a Chemist and studied physics as well. My Grandfather was a mechanical engineer, and used to call me his little engineer. Although he passed many many years ago, I could not get his voice out of my head.
The fix: First after struggling (like many youtube videos said) to get the cover off, I cleaned it out gently by blowing, and oiled the heck out of everything. Ran the mechanics well until it was running smooth.
Second: tension issue/bird nesting-----After making sure that the motor and all parts was running smoothly--nothing broken, no plastic parts were chipped etc, I turned to the bobbin area. There is a metal plate with a little notch that had 3 screws in it. It sat under the bobbin area cover, and the bobbin casing slides under it. I have no idea what the real name is for it. The plate slid left to right, moving how much it pressed on the bobbin casing. I had to slide this plate to just the right position to keep the bobbin casing from bouncing around, but also not to tight to prevent it from spinning. I am now sure that this was the cause of the bird nesting.
One down one to go!!!! New thread about that second Sonata issue to follow.
