Cobra class 26 Bobbin tension??

Recommended Posts

I just got my class 26 in the other day. I'm running into a problem where the stiching seems to be laying on top of the leather loosely. At first glance the stitch looks good. No high or low stitches. But they are loose. 

I believe that I need to increase the Bobbin tension, tightening it. Then I can adjust the upper tension. But apparently the class 26 has had a Bobbin upgrade since the last time they made their instruction manual. 

As soon as I can I'll send a picture of the new bobbin system. 

Has anyone come across this issue

well, the tension parts on sewing machines have not really changed significantly so I´m sure it is the balance between top and bottom tension you have to figure other than that make sure the top thread comes off the spool w/o hanging and nothing in the top thread path is causing drag or additional tension.
