Double check you are threading correctly for bobbin winding. It should wind neatly till it can't turn, and then you stop winding; at least this is how it works on the 8000. Perhaps there is some thread blocking the thread guide for the bobbin winding

Winding a bobbin correctly

The heart of sewing is producing a well tensioned seam and achieving this with any sewing machine will be difficult if you don't wind a bobbin smoothly and with even tension onto the thread. If you look at your bobbin and the thread on it looks all lumpy and uneven, then this tip is for you.

Each time you wind a bobbin, whatever sewing machine it is on, it is really important to keep even tension on the thread as it winds onto the bobbin. Many machines will have a little tension disc you take the thread around but your technique is important too.

Usually you take the thread from your spool of cotton on the right, across to the left on the top of the machine and around a tension disc, or through a thread eye, then back to the right to your bobbin winding spindle, if your bobbin has holes in it, then pull the thread tail up through a hole and pop it onto the spindle. Engage the spindle by pushing across against the stop. Now start winding SLOWLY while holding the thread tail up in the air until the core of the bobbin has been covered in fully and your thread has covered up the starting point to hold the beginning tail. Stop winding, and trim the tail off against the bobbin with a pair of snips. Now resume winding at 1/2 to 3/4 speed and do two things, one with each hand. With one hand put tension onto the top of the spool you are winding thread off - use the curve of your scissors handle into the indent on top. And with your other hand, give the thread a nudge as it winds onto the bobbin to ensure you wind fully across the whole bobbin evenly. Watch it carefully to ensure that you get a smooth even wind.

An analagy: if you wind the garden hose onto the hose reel really fast and let it go anywhich way, the hose will kink and wind mostly in the middle then the reel's full and you've still got half the hose to put away. Thread is the same, its been wound onto a spool by a machine in a very precise way; you want the same smooth evenly tensioned winding onto your bobbin so that when you stitch out the seam the thread is consistently fed off the bobbin.

Don't be tempted to wind flat out and just let it take its own path as you won't get good smooth bobbins of thread. And if you let the thread come off the spool at a fast pace the spool may bounce around, causing fluctuations in the tension on the thread. When you stich a seam, the thread will relax unevenly in your seam causing puckers and ho hum stitching.

Simple stuff but it makes a difference!

My bobbin winds unevenly, there is always more thread at the bottom of it than there is at the top. Neither switching to the original pfaff bobbin nor either spool position works.

I always use my finger to guide the thread as the bobbin is winding,the bobbin shouldn't be moving around in the metalcase probably needs tightened.

Why does my bobbin winder stop prematurely?

Define "prematurely". Bobbins shouldn't fill to the edge of the bobbin. Are they wound evenly? Uneven winding can cause the winder to stop early.

Loose boobin winding

You need to ensure that the thread is going from the thread spool at the back of the machine, through the eyelet, then around the silver tension disc on top of the machine, then to the bobbin when you are winding it. Also, pull the thread tail up through the hole in your bobbin to start and hold the tail so the thread starts to fill smoothly and doesn't loosen.

I've marked the disc in red on this image
Please read my Tip on bobbin winding; its really important to get a good wind and you can add more tension yourself by applying gentle pressure to your thread spool on the back pin as you wind off it.

The stopping when full is possibly because your bobbin is winding unevenly but I never run it until it stops itself anyway, and do the winding at 3/4 speed, not flat out. You want a really smoothly tensioned even wind onto the bobbin so your thread comes off the bobbin when stitching with even tension, not stretched, then loose.

Hope this helps you with your problem.

Stiches are uneven & the thread bundles up on the back. I have lost my instruction book, so it is hard to slove the problem. If you could send me a new one, I will pay you for it! Linda P...

you can download a manual from here

If you are getting loops in the thread underneath check your top tension, thread is probably not into the tension discs fully or at all. If you can get at them, clean between the tension discs, turn tension knob to zero, then "floss" between with the selvage edge of a clean piece of cotton fabric to remove any dye buildup or lint. Cheaper threads will shed fibres as they go through tension so best to avoid those bargain bin threads, fine for hand sewing but not so great on the machine long term. If you can't get at the tension discs then consider having a clean and service at least bi-annually to keep them clean as well as the other internal moving parts.

Uneven stitches can be caused by a blunt needle - you should put in a new one for each new sewing project (4-6 hours sewing time) ensuring it is a sharp for wovens or ball point for knits. There is a great guide to needles at

Also review how you wind the bobbin, there needs to be tension onto the thread as it goes onto the bobbin, there might be a silver tension disc on top the thread goes around. Wind slowly, and apply a little pressure onto the top of the thread spool you are winding off - your scissors handle is good. This stops the spool bouncing around causing uneven tension on the thread. If the thread is stretched, then relaxed as it winds onto the bobbin, then it will go back to its normal position in the seam causing puckers.

Here's how I wind - take the thread from the spool across to the tension disc, then back to the bobbin, put thread tail through the hole on the bobbin and hold the tail. Pop bobbin onto bobbin winder spindle and click across to engage. Hold the tail and start winding (might be a button on your machine, or just the foot control), wind just enough to go across the bobbin core and hold the starting point. Stop and snip off the thread tail with your scissors. Restart winding slowly while putting some pressure onto the thread spool with your scissors curved handle into the top (I usually use Guttermann thread and they are tall spools coming up past the top of the pin, this might not apply if using a shorter spool but put some pressure onto it). Watch the thread going onto the bobbin and give it a nudge with your finger tip to ensure the thread fills top, middle and bottom of the core evenly, you don't want it all on the bottom or all in the middle.

Wind until 3/4 full, then stop, cut and remove from the spindle and return machine to normal sewing mode. If you have a mushroom type cap put it onto the thread spool now so the thread winds off smoothly as you sew. Also put a felt circle under your thread spool to assist smooth thread flow.

Also, have you cleaned in the rotary hook? You should brush this out each time you use the machine and refering to the manual, remove the bobbin holder/case and clean under it. All machines will get lint/thread bit build up in the rotary hook and need regular cleaning out to prevent impaired operation. Your machine probably also has a oiling wick under the holder, in a little depression in the middle. Don't touch it but you can give it a drop of good quality clear sewing machine oil every few months. Manufacturers would like you to give the machine to them annually for cleaning/lube etc but you can certainly do some cleaning regularly yourself to prolong machine life and keep it running smoothly.

Also, keep machine covered when not in use, never in full sunlight (plastic will yellow) and not in a damp area.

I hope that these tips help you a little, certainly if you try all the above and the machine still isn't performing as it should, then take it back to your dealer and ask them to test sew and confirm if it needs a service. A good dealer would do this for you ( I usually ring first so I don't get them at a busy time though). I have my machines serviced every two years and clean/oil myself each month in between.
Happy sewing.

Bobbin stich is uneven and a tangled mess

you can dowload a manual from the singer website

If the bottom stitching is uneven, its mostly the top thread not under tension correctly so check the tension dial and the threading up from the thread spool to the needle.

Also, review how you wind a bobbin, you want a nice smooth wind, not twisting or uneven build across the bobbin. The manual for this machine is pretty brief on this but bobbin winding is crucial to getting a good even flow from the bobbin when stitching seams. You want to wind thread smoothly onto the bobbin, across the full width of it, not just mainly in the middle. Give the thread a nudge with your finger tip to fill top and bottom as it winds.

Also, ensure the thread goes through the bobbin tension disc on top of the machine, and even then, use your scissors handle to put some downward gentle pressure onto the thread spool you are winding off so it doesn't jump or bounce as you wind. Wind the bobbin to 3/4 full, then stop.

And lastly, load the bobbin correctly following the manual directions, make sure it is turning the right way in the bobbin case. Also look at page 16, it shows the "dangle" test where you can check the tension on the bobbin case is right, you should be able to dangle the bobbin by the thread tail and it should "stay" but you should be able to pull on it to release thread too. Adjust the little tension screw in minute increments to get this right. Bobbin case tension springs can fail or break too, so check this out.

Hope this helps you; it is my experience that 90% of machine issues are caused by blunt or wrong sized needles, wrong threading, no tension or incorrect tension or lack of maintenance.

Why is my machine skipping stitches

this is caused by uneven winding of the bobbin, sometimes the spool of thread winds unevenly when it travels up and down the spool. the best solution i have found is to use small spools of thread when winding the bobbins

Singer 9410 bobbin problems

It should not affect the winding, the reason the needle is still going up and down is because the oil has gone dry on the shaft and unless you can get to the shaft where the balance wheel is then it would be wise to take the machine in for a service, loose stitching on the bottom is a tension problem, make sure the top tension is set about 4 or 5

Bobbin does not fill completely

Machines that stop the bobbin winder automatically when the bobbin is full have a mechanism that detects how much thread is accumulating in the bobbin while it is winding, then stops the winder when the bobbin is full. It is likely that the bobbin winding mechanism needs to be adjusted by a mechanic. 
On the other hand, if the thread winds evenly, and stops winding when the bobbin is about 3/4's full each time, you probably don't need to worry about it if all else is good (even tension, consistent stitch quality, and so on). 
If you'd like me to post some general troubleshooting tips, let me know.
Good luck
