Take out your bobbin case... there should be a small screw fixture on the side of the case...turn screw anti clockwise until you get the correct tension ... To test the bobbin thread tension...Remove the bobbin case keeping bobbin attached and hold it by suspending it by the thread...**** it once or twice, if the tension is correct the thread will unwind by about an inch or two. If it does not unwind at all...tension is too tight. If the tension is too loose it will drop too much. Goog Luck

I am not sure about this particular machine but in most machines there will be a nob on the front loose low numbers like 0 1 -2 work well on number 3. If the nob is not on the front check and see if it is on the side.

I need elp with tension on singer cg550


You didn't explain the symptoms. Is the thread bunching, looping, knotting under the fabric? Is the bobbin thread rising to the top of the fabric?

If it is bunching under the fabric, it is probably what is called thread nesting or bird nesting. There are several fixes, sometimes more than one fix is required to resolve the issue.

Be sure to clean under the needle plate, around the bobbin, and the feed dogs. If the machine has instructions for oiling, follow the directions using a fresh, good quality sewing machine oil and apply only 1-2 drops each spot.

Install a brand new needle. Make sure you are using a needle compatible with the thread and fabric being used. All About Needles
Best practice is to use the same thread in both the upper and bobbin. Also, avoid old or bargain bin thread. Spend an extra couple of dollars to reduce frustration and increase success with your machine. If you wish, you may use two different colors of thread to test so you can easily determine what is happening with the tension.

Remove the thread from the machine. RAISE the presser foot and rethread from the beginning--the thread needs to be seated firmly in the tension disk. Verify that the correct thread path is followed (consult the owner's manual).

Set the upper tension to the midway point between high & low numbers (this is the factory standard and is a good place to start, but every machine is different and may need adjustment).

Confirm that the bobbin is installed in the bobbin case (turning the correct direction) and that the bobbin case is threaded properly.

Before beginning to stitch, hand rotate the handwheel one rotation and pull the bobbin thread to the top of the fabric. Then, gently hold the thread tails in the left hand and slowly begin to stitch.

Test.

If thread is bunching, looping under the fabric, the upper tension is too loose. Tighten it and retest. On most machines, the lower the tension number, the looser the tension.

If the bobbin thread is rising to the top of the fabric, the upper tension is too tight. Loosen the upper tension and retest.

Keep adjusting and testing until it is where you want it. Generally, tension is correct when both threads (upper & bobbin) meet in the middle of the fabric. FWIW, tension is static and should be tested and readjusted every time a new project is begun. The needle, thread, and fabric will affect the tension, so it is important to get comfortable adjusting the tension.

Also found the following reviews. Appears that some users have had tension issues with their CG550.

Singer 301 won't stitch properly, thread bunching up on underside


Likely that it is a lower tension issue
Bottom tension is controlled by the bobbin case. First, ensure that the thread is wound tight onto the bobbin (should not be spongy when you push your fingernail into into it) Looking at the open side of the bobbin case, insert the bobbin into the bobbin case (so the thread winds off in a clockwise direction) and feed under the 'tension finger'. If you now hold the end of the thread, suspending the bobbin and case from it, the assembly should not drag any more thread out of the bobbin case. If it does, the small screw on the tension finger needs to be tightened slightly. If the assembly does not drag out any more thread, give the thread a little upwards tug. The assembly should slide down a little.If it does not slide, the tension finger is too tight - loosen it a little.
Insert a NEW needle, make sure the top thread is correctly threaded and tension is set at the 'normal' setting (as per book) ..... .... try sewing a sample. Note: using 'cheap' thread will cause all sorts of tension issues as well as fluff up your machine fast - avoid it!
Good luck

Singer 7468 birdnest issues


:) If you are nesting below the fabric and in the bobbin area... that is an upper tension problem. Tighten the upper tension... and try again.

Keeps breaking thread or thread get hung up in the bobbin area.


This is caused by any one of a number of issues. The most common ones are as follows:-
  • Using the wrong needle for the type of thread
  • Too low a top thread tension
  • too high a bottom thread tension: as this is non-adjustable it suggests an incorrectly threaded bobbin or a bobbin which is wound too tightly
  • Using poor quality non-Singer needles
  • Using poor-quality thread of the kind often found in discount stores

How do i fix a birdnesting problem with my singer 5050c sewing machine , or do you have instructions of how to thread the machine.


Try adjusting the tension. It sounds like the bobbin thread is too loose or the bobbin is not in correctly. Try taking the bobbin out and turning it around and putting it back. When you hold the bobbin in the fingers of your left hand and you pull the thread out with your right hand the bobbin should be turning clockwise. If the nesting persists, try ajusting the tension one way and then the other to see which seems to help. Hope this helps!

My Singer 5050C wants to bunch the thread underneath


Make sure to thread machine with the presser foot raised. Then make sure thread gets in between the tension discs and that you have the machine threaded correctly with the thread going up and into the take-up arm. tension should be set at 4-5.
