Singer Sewing Machine Tension

My bobbin thread tension is very loose.  I saw somewhere that I could adjust the leaf spring tension on the bobbin case?  I need to finda a tiny screwdriver before I attempt that.  I was using my sewing machine two days ago and it worked great.  I had to make the tension very loose to pull the threads to make a ruffle on a Halloween costume.  I have also changed the thickness of fabric that could of affected my problem.  And of course I can't find my manual and need to finish up my project.

This is an answer to another person with a similar complaint. Try the suggestion below, it may fix the problem.

From your description it appears that you have tried tension settings on the upper tension control adjustment knob without success.
Check that the bobin tension is adjusted correctly by taking out the bobin complete with the spool.
Pull the cotton thread and it should be a smooth light pressure if the tension is correct. If it is tight to pull or pulls freely then adjust the tension screw which is found on the outside of the bobbin. The screw is very small and requires a minature size screwdriver. The adjustment will only be a slight turn of the screw one way or the other to obtain the correct tension(depending if it was loose or tight).
Once this is set reinstall the bobin and tread up the machine, hopefully with the upper tension set at approx."2" the machine will sew correctly.

SOURCE: Thread in needle or bobbin keeps on breaking

The tread only breaks in the needle. what can i do . i don't get to sew anything . I tread the needle and get everything ready and start the machine and as quickly as that the tread is broken and the machine has not sewn at all.

SOURCE: Difficulty adjusting tension to avoid bobbin looping

it sounds like your bobbin tension is too tight. to adjust bobbin tension, remove bobbin case (remove needle plate first) and adjust bobbin tension screw on side of case until bobbin thread has a slight resistance as you pull it through the bobbin case.

this will be trial and error until you get best result. you should always try and match top and bottom threads. if the top thread is quite thick you may have continue to increase needle thread tension until balanced.

Upside down stitching

Am having a difficult time picturing this. Sounds like the upper thread is creating loops under the fabric and the bobbin thread is showing on the top of the fabric.

Make sure to use a brand new needle.

Remove the thread from the machine
ALWAYS raise the presser foot and rethread the upper thread.
Make sure the thread path is correct.

Check that the bobbin is turning the correct direction in the bobbin case and the bobbin thread is threaded through the bobbin tension correctly.

Set the upper tension to the midway point (factory standard), however, this setting may need to be tweaked for your particular machine.

Bring the bobbin to the top of the project Before beginning to stitch.
How and Why to Bring up the Bobbin Thread

Retest--begin sewing slowly.

If the upper thread is still showing on the other side of the fabric, the tension is too loose. If it is pulling the bobbin thread up to the top of the fabric, the upper tension is too tight

OR the bobbin thread tension is too loose. (CAUTION: make only small adjustments to bobbin tension--1/8 of a turn at a time!!! It also helps to mark the screw groove location with magic marker on the bobbin case BEFORE making any changes so you can back it out and return to the original setting.)

Why is thread getting caught and unable to pick up the bobbin thread?

try tightening the needle thread tension as it appears to be too lose
try loosing of the bobbin thread tension a fraction as it may be to hard to pull out of the bobbin case under the spring
changing thread sizes and material thickness generally requires a tension adjustment of the threads

I have a VX1250. I don't know how to regulate the tension.

There is two places to adjust thread tension: the top tension device controls the top thread tension and is usually a dial or knob with numbers on the front of the machine.

Then there is some form of tension device on the bobbin; in your case I believe the Brother has a removable bobbin case with a tension spring which holds the bobbin thread firmly: the tension spring can be adjusted with a screwdriver but once set, you shouldn't need to adjust this much, just alter the top tension slightly for different weights of fabric. So start by setting top tension dial to 4-5 and test stitch a seam. Use different coloured but the same type of thread top and bottom and take a look at the seam. You want to see a balanced even seam.

Here is a link to a great info site for this:

If the bobbin thread is too loose, then you probably will need to finess the tension spring on the bobbin case and adjust this slightly. The best way to set the tension on the bobbin case is as follows. Load the bobbin into the bobbin case and pull the thread tail into the tension spring, then suspend the bobbin by holding the thread tail up in the air (the dangle test). You want it to be just tight enough to hold its own weight, but still able to release thread when you pull gently downwards on the bobbin case. If it isn't doing this then take your little screw driver and adjust the screw on the leaf tension spring by ONE QUARTER TURN ONLY. Lefty looser, Righter Tighter. Then test again, and adjust again until its right.

Now test stitch again and finess your top tension to get the seam even. Remember to change the needle for each new sewing project too; this will impact tension also.

Bottom thread too loose; tried rethreading top thread, cleaning bobbin case, refilling bobbin, changing needle, adjusting top tension

Check for correct bottom thread tension.
It's provided by a flat spring on the bobbin holder.
When the bobbin is correctly installed, pulling on the thread
should meet with slight resistance, and the bobbin should spin without
trying to jump out of the bobbin holder.

Bobbin tension on Viking 350 Sewing Machine

Viking bobbin case tension adjustment:
When the bobbin runs out, sometimes it bends the bobbin case tension spring. Then tension is too light. Take the bobbin case out of the machine. Tie the loose bobbin thread to the Designer 1 needle plate. Insert the bobbin in the bobbin case. Here’s the tricky part set the bobbin case on the table as if it’s in the machine (Bobbin is visible and sitting horizontal to table top) threaded as if sewing and loose end tied to needle plate (that is removed from the machine). Lift the bobbin case off the table rotate it so that the flat side of the bobbin are vertical to the table and no longer horizontal. Have the bobbin case oriented so that the thread coming out of the bobbin case sprint (slot area where it is put for sewing) is at the top. Lift it high enough that the needle plate is lifted from the table. It should not release thread unless you shake it gently and then a very small amount of thread. The needle plate is the exact weight resistance your bobbin case should have on the thread.

Problems with Singer 2732

"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.

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.
