It was doing this before took it in to shop they replaced some gears cleaned and adj it. I t has not been used much, the thread knots up under material and sometimes around the bobbin. trying to replace a zipper now, i have un threaded it sev times checked for loose thread under machine etc
"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.
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.
What size needle are you using?
Last thing. Try loosening the presser foot so that it's light pressure.
If you haven't found a solution try a number 18(110) needle. Good luck.

yep it is unwinding counter clockwise. i dont know how to adjust tension on the bobbin the other tension i have tried at 0 to 5. putting a zipper in a coat. i have hemmed up jeans with minimal problems but i may throw this out the door in a minute
thread balls up under material on singer 6412
i have tried rethreading it several times, thank you though.
still balling up does any one have another idea, where would the correct tension be for a ski jacket
bobbin is smooth, bobbin case moves a good 1/2 inch forward and back is that normal?
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
still balling up with new needle, clean bobbin case any other ideas?
needle is a singer red band style 2020 size 100/16 #2077[4731] says its for heavy weight and denim
have the tension at a 2 and i cant even get 3 stitches before it is a mess
it is set to 0 now and all bobbin area is clean.......i thing it needs to go out the door for a new machine thats hardly been used it is sure crummy
