I am trying to make a rag blanket and the tension on my machine loops on the underside. I am about ready to throw it in the ditch. How do you fix the tension on a 9410 singer machine?
How to fix the tension on 'any' sewing machine. I may know how (family in the sewing business for 50 years-all now retired).
To begin with:
1) Put in a new needle;
2) Re-thread the top thread;
3) Lower the foot;
4) If the needle threads from front to back (or r. side to l. side); begin pulling the thread through the needle in the direction it threads, while slightly tightening the top tension knob, wheel, or other tightener. The tension on the top thread should bend the needle quite a bit, without breaking it (for cotton material sewing). If you're sewing a lighter fabric, the top tension should be slightly looser;
5) Once you have the top tension adjusted, re-thread the bobbin case, with the thread coming to you, out of the bobbin, having the thread escapement on the 'top,' while the bobbin case is in your right hand, and the bobbin is visible on the left side. Your instruction book may say the opposite way, but this is really the correct way to do it, as the new threads have many knots in them, and the bobbin case will stay correctly threaded doing it this way; next,
6) loosen the little screw on the flat spring, that presses against the thread on the thread escapement of the bobbin (if it is currently tight);
7) If the thread is easily pulled through the thread escapement, slightly tighten the tread, so a firm pull is needed to bring the thread out of the bobbin case. Not to tight though (or you will get loops on the bottom of your seam. You may have to tighten a little, or loosen a little. The 'knot' of each stitch should be in the middle of the cloth. If the bottom tension is too tight, the knot will be on the bottom; if it's too loose, it will be on the top. When it's just right, it will be in the middle;
8) When you change weights and types of fabrics, you may have to re-adjust your tensions; but, the process is the same.
Just remember: Always begin with a new needle, and always 're-thread' your machine.
I hope this helps.
P.S. My father set up many of the Viking dealers on the East side of the Mississippi. I worked in the business all the time I was going to school, and a couple of years after the service (early 60's). I used to 'dream' about sewing machines, and finally got out of the business, but I still fix machines for my family.
Good Sewing, and
