Gammill Classic tension
Q. I machine quilt on a Gammill Classic longarm. I am trying to use So Fine thread on top and Bottom Line in the bobbin. I cannot get my tension adjusted right . I've got my upper tension as loose as I can get it, I think. Bottom tension is fairly loose. Most of the time my bobbin thread is laying on the back like its not being pulled into quilt. I tried tightening toop tension- it doesn't seem to help. Are there any suggestions you can share about using the threads on my Gammill? I use the Lava thread most of the time and I LOVE IT!! Thanks
A. If the bobbin thread is just lying on the bottom, either the top tension is too loose (not pulling it up) or the bobbin tension is still too tight (keeping the thread underneath). So Fine is usually the easiest of all threads to use. Here's what I recommend:
1. tighten the top tension more and see if that will pull up the bobbin thread.
or
2. Switch the bobbin thread to So Fine also and see if that fixes the problem.
