coheteia Report post Posted August 22, 2014 I just bought this machine on Monday for making moccasins and thin sandals. I am new to leather working as well as new to sewing in general. Overall, I am pretty happy with the machine. However, regardless of how I adjust the tension, the bobbin thread shows on top. Can anyone tell me what might be the problem? My first guess is that the bobbin tension needs to be adjusted but I am relatively clueless and I would love some advice before a mess anything up by tinkering with the machine. Thanks ahead for any advice! Quote Share this post Link to post Share on other sites
Northmount Report post Posted August 22, 2014 Too much top tension pulls the bobbin thread up. If the top tension feels fairly light, then the bobbin tension needs to be increased. Large needle size makes it easy for the top tension to pull the bobbin thread up too high. It is a balancing act. Check your needle size vs thread size first. Look at this thread needle chart http://www.tolindsewmach.com/thread-chart.html. I'd try the top tension next before increasing the bobbin tension.
