Thank you all for your response. I have oiled it and cleaned it up and ran it without thread with bobbin in place at slow speed then fast speed. I will have to try tighting up my quilt or loosen it. It is just a practice quilt to learn on anyways. But as for thread balling up in bobbin case it does do it when it locks up. It makes a loud horrible noise when it does it. It sews fine fir a bit then all of a sudden it just jams. I have been to baileys site but i guess i should call them if i do not get it figured out. I changed the thread and the stitches where loose so i got the tension good on the different thread. I do have another quilt machine i can try also that i got on a really good deal. It is a singer industrial from the 80's. Thanks again for all the input.
