Members TammyNYC Posted March 5, 2021 Members Report Posted March 5, 2021 I have a Singer 111w155 with a new Servo motor. I can’t get even, tight stitches. I’ve had loops on the top and the bottom and skipped stitches. I’m using size 69 thread and sewing through 2 layers of 3 oz. leather for the most part. I’ve noticed it’s better with thicker leather. The screw for the bobbin is so tight that I can’t move it. For that reason, I haven’t adjusted bobbin tension but, adjustments to top thread tension haven’t done much. Quote

Members Constabulary Posted March 5, 2021 Members Report Posted March 5, 2021 (edited) Solve the bottom tension problem first. It may bother you in the future again so better get it done soon.Try to apply some heat to the tension spring + screw and try again. If you have problems reaching the tension screw then remove the bobbin case from the hook. Maybe there is dirt under the spring or spring is worn... just check it. Maybe buy a new bobbin case if you can´t remove the tension spring (check parts number on bobbin case) or the screws are messed up.
