    thread balls up under material on singer 6412

  • mhenry5694 Dec 31, 2008

    i have tried rethreading it several times, thank you though.

  • mhenry5694 Dec 31, 2008

    still balling up does any one have another idea, where would the correct tension be for a ski jacket

  • mhenry5694 Dec 31, 2008

    bobbin is smooth, bobbin case moves a good 1/2 inch forward and back is that normal?

  • mhenry5694 Dec 31, 2008

    ok took the case out and made sure there was nothing in it and reinstalled it, for a ski jacket would you want the tension like a 1 or so or like a 5 would you guess. bobbin case is smooth too and it is wound fine, thanks for helping me

  • mhenry5694 Dec 31, 2008

    still balling up with new needle, clean bobbin case any other ideas?

"Birdnesting" occurs when there is no tension on the needle thread to pull the bobbin thread. This is easily corrected by rethreading the machine, following the threading path carefully and making sure the thread is fully engaged in the tension mechanism.



Good luck ..

Look to see how much thread you have left up top - if the spool is almost empty, it will affect the tension and cause looping.

For somthing as smooth as nylon you are going to need a very high tension! set tension to highest level and work your way down! also make sure bobben area is clean and free of any old thread!~

Did you remember to put the bobbin in so it unwinds counter clockwise? Also you can increase the tension on the bobbin. Try these and let me know what happens. Good luck.

    You may have burrs on the the bobbin itself. Take out the bobbin and run your finger around the edges of the bobbin. If you find any sand them smooth or use another bobbin. Also make sure the bobbin case is clean and drop a drop of oil in it.

  • David Robinson Dec 31, 2008

    Yes, it flops around in there. Is the bobbin wound neatly or does it have loops in it. If so wind a new bobbin and try that. Or,

    Try replacing the needle. Sorry we're not getting anywhere.

  • David Robinson Dec 31, 2008

    What size needle are you using?

  • David Robinson Dec 31, 2008

    Last thing. Try loosening the presser foot so that it's light pressure.

  • David Robinson Dec 31, 2008

    If you haven't found a solution try a number 18(110) needle. Good luck.

How do I fix the looping under the material when I sew?


the looping on the bottom usually is a tension problem, the top & bottom tension are unequal usually fixed by adjusting the top tension.
some people that I've talked with have had success with changing to a different size needle ( depends what type of thread is being used).
when the machine is threaded the foot needs to be up ( this releases tension on the thread), when the foot is lowered it the tension is set on the thread. if the material being sewed is too thick it raises the foot too high & releases tension on the thread ( the material has to be really thick to do this).
if there a piece of thread or lint in or around the tensioner or bobbin area it could cause trouble.
other wise if you've tried everything you can think of, take it back th the store & have them try it & tell you what is wrong.

also this machine has bad reviews (i'll provide a link so you can read them), people having the same problems as you are. the newer singers just don't seem to be the same quality tha the older ones were.

I hit a pin with my Singer Stylist 7258. It jammed. I changed the needle, rethreaded it, and turned it off and on, but it snarls up thread under the fabric, and seems that the thread does not always loop...


Good that you changed the needle. Did you rethread just the needle or did you rethread the machine? You may have already taken these steps, but if not, here is what I would suggest:

1. Replace the old needle (which you did), even if it looks ok, as it may be bent or have a tiny burr or other damage that isn't easily visible. Make sure the needle is seated properly - facing forward and fully inserted.
2. **Completely rethread the machine, making sure the thread is going through the take-up lever. It can easily pop out when the machine jams, and you can't always see that the thread is out of place. That could explain why the thread doesn't loop properly around the bobbin.
3. Remove the bobbin and clean any knotted thread or lint from around the bobbin carrier. Canned air is great for cleaning the lint.
4. Replace the bobbin, making sure the thread-end is clipped neat, not frayed or knotted.
5. Try sewing on some practice fabric to make sure the stitches are going to form properly before returning to your sewing project.
Good luck!

I have a Euro-Pro 7500. I can't seem to sew a straight stictch without the thread binding up from the bottom of the material.


Do you mean the thread knots and loops up under or over the fabric? If so it sounds like you need to re-thread. You may have not put the thread into one of the tension wheels correctly. Keep the presser foot up when you do it.

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
God's Blessings,

My machine isn't quite picking up the bobbin thread. It brings up the loop of the bobbin thread, but I can't pull the bobbin thread through the back of the machine - it's like the top thread (I think) is...


It definitely sounds like tension adjustments,m make sure the top tension is about 4 or 5, you should only just about be able to pull the bottom thread through with some resistence, if it is too tight slacken the screw about a quarter of a turn anti clockwise and test sew and keep doing that until you get it right.

Bobbin won't thread


If the hook is not spinning then it needs a gear job which will cost you anywhere from $150 to $250 depending on who you take it to. This machine has four plastic gears which should all be replaced, don't just replace the one that is stripped as the others will go bad soon since they are the same age.
You may be lucky in that something has only come loose, but if they are the original gears then most likely is that they need to be replaced.
Good luck!

Thread on bottom, bobbin thread loose


Sounds as though you've misthreaded the upper tension. The best way to verify this would be to thread your machine, lower the presser foot on to the material. Now try pulling the thread through the needle. (Assuming your upper tension dial is set to a number greater than one). You should feel resistance. Should you not feel resistance, rethread your upper tension.
