Do you have it extended all of the way? You have to pull up on the spool pin to put your thread spool on.

Can't figure out how to fill the bobbin

hi Beverly.
you have not said what make and model.
but try this.
Always wind the bobbin before threading the machine and needle.
  1. Place spool of thread on spool pin.
  2. Slide spool pin holder/cap firmly over rim of spool to prevent thread from tangling.
  3. Push bobbin winder pin to far left if it is not already there.

I have a brother xl5012 and would like to change the spool pin..not sure if its broken? the one on top is silver and the spare is plastic..not sure what to do..the manual has no answers.. thank you

On most machines, the spool pin simply screws into a threaded hole. If it was welded on or attached in some other permanent way, changing it may need a service visit. Brother has one of the very best service departments of any company I know. But try to unscrew the old one.. it might be stuck, a drop of penetrating oil, or maybe some pliers, might assist. If it comes out, a new one should screw in easily enough, so long as it matches the size of the hole and the threading.

Bernina artista 180 bottom stitch bunching

bunching under the material is bird nesting is a result of loose needle thread tension thread the machine up to the point of threading the needle
pull on the thread and you should have a reasonable resistance to pulling the thread
adjust the tension until you get that then thread the needle
while you may be using the tension settings if there is a problem in the tension plates area , the tension will not get high enough regardless of the indicated setting
bobbin tension can be reasonably loose
correct tension is when both threads meet at the center of the materials being sewn

Spool pin not come up

You may have to take the machine apart to get the spool pin. Shake the machine to see if it is loose inside. If you can see the top of the pin a very very strong rare earth magnet may be able to retrieve it from the outside. If the pin is not causing problems inside the machine you can use a thread stand or install another spool pin on the outside of the machine with a pop rivet gun.

Threading a bernina

Depends on the model, for detail but basically: Ensure the takeup arm / needle is at the top of its motion - with electronic models this is easiest done just by 'blipping' the foot controller and the needle will automatically return to top. Put your spool of thread on the spool pin. On older models with the vertical spool pins ALWAYS use a felt pad underneath to prevent the spool spinning when the thread is drawn off. On later models with a horizontal spool pin, hold the spool in place with the correct size retainer, with the larger diameter facing away from the spool. Make sure the foot is up (this is important). Draw thread off the spool and route it through the pre-tensioner on the back of the machine, then through the slot until it passes through the tension discs next to the tension control. The thread is then brought down the right-hand-side of the takeup arm cover, and pulled-up the left-hand side (it should be pulled into the check spring at the bottom, automatically. Pass the thread around the right-hand-side of the takeup arm and then the left-hand-side so that the thread is left running through the takeup arm. Drop the presser foot. Route the thread behind the lower thread guide at the bottom of the takeup arm cover and then through the thread guide at the bottom of the needle bar, just above where the screw that retains the needle is situated. The thread guide might be a simple loop of wire or a clip on the botom of the needle bar. Thread the thread through the eye of the needle either manually or using the needle threader, if fitted and off you go. It's important to have the foot raised when routing the thread through the upper tension discs to make sure the thread sits properly within the discs rather than just going over the top of them. Raising the foot holds the tension discs open.

How do I pull up the spool pin?

from the questions I read, this has happened to alot of people.
normally the spool pin should be easy to pull up with 2 fingers, if it's not then most likely there could be something wrong, you can try to use a pair of pliers to pull the spool pin up,, but if it's come loose or broke then it will have to be replaced. and some sewing machine are not mint to be opened by anyone except a factory trained technican.

Need to put bobin in a merritt 4530

Flip the presser switch up to raise the presser foot. Turn the hand wheel counterclockwise until the needle is in its highest position.
  • 2Hold the hand wheel in place with your left hand while turning the hand wheel knob counterclockwise with your right hand to loosen the hand wheel knob.
  • 3Place the desired spool of thread on the spool pin so that the pin fits all the way through the hole in the center of the spool. Put the spool holder onto the end of the spool pin that is sticking through the spool of thread and press firmly to ensure that the spool holder keeps the spool in place.
  • 4Grasp the end of the thread and hold it taut between the thumb and index fingers of both hands. Snap the taut section of thread into the thread guide post located to the left of the spool pin.
  • 5Pull the end of the thread gently. Wrap the thread around the bobbin winder tension disk near the left front on top of the machine, starting at the side of the tension disk facing you and wrapping around in a clockwise direction.
  • 6Poke the end of the thread through the small hole in the bobbin from the inside out so that the loose end of the thread sticks through the top of the bobbin. Put the bobbin on the spindle, or bobbin winder, and gently slide the bobbin winder to the right.
  • 7Hold the loose end of the thread in place while pressing down on the foot pedal to start the machine. Hold the foot pedal down until the bobbin is as full as desired. The machine will automatically stop once the bobbin has reached capacity.
  • 8Cut the loose end of the thread using scissors. Slide the bobbin winder to the left and remove the bobbin. Hold the hand wheel in your left hand and tighten the hand wheel knob with your right hand by turning it clockwise

    Hi why does the machine skip stitch ,or Cather at the bottom ,the problem occur while am sewing.

    check to see if your needle is bent-roll on flat surface to see if it roll good
    if the needle make a popping sound when going thru fabric it is blunt
    the needle is incorrectly inserted in needle clamp holder
    needle & thread not compatable with project
    check for warped bobbin
    rethread machine
    check bobbin area for lint or loose threads
    check to make sure thread is not caught on any thing-such as spool pin-notch in spool of thread

    Necchi sub22 - threading info / bottom stich/ spool

    This may be of help:

    How to Thread Necchi Sewing Machine

    Even though your machine is probably a different model, machines generally thread the same.

    Something that may help is ALWAYS RAISE the presser foot when threading the top thread. This allows the thread to seat fully in the tension disk and helps eliminate those loose threads under the fabric.

    If the bobbin thread still just lays on the fabric, the top tension is too loose. Tighten the top thread tension so it will pull the bobbin thread up into the fabric. Tension is a tug-of-war between the top and bobbin threads. Neither should win nor lose. Tension is accurate when both threads meet in the middle of the fabric. Also, keep in mind that tension is not static, ie it will most likely need to be adjusted whenever you begin a new project because the thread, fabric, needle, and stitch selection can change the tension.

    You shouldn't need a separate spool for the top thread if your machine has the vertical spool pin. Most spools will work unless you are trying to use the huge spools that are made for sergers. In that case, you can wind thread onto a bobbin and then use the loaded bobbin as your top thread--in effect, you would wind 2 bobbins, one for the bobbin thread and one for the top thread. If my thread spools are taller than the spool pin (causing the spool to flop around when I stitch), I simply slip a plastic drink straw over the spool pin and, Voila!, the spool pin is taller than the thread spool.

    Another helpful hint: AVOID using old or bargain bin threads. Quality thread will limit a lot of sewing problems and frustration.

    Install a brand new needle every 8 hours of sewing time. Frequently, problems are a result of using old, damaged, or dull needles. When having problems, the first course of action is replace the needle. A lot of time can be spent trying to find resolutions to a problem when a brand new needle is all that's needed. If you hear the needle strike something strange, it's probably best to replace the needle as it has probably been damaged or bent. A hard strike of the needle can knock the machine out of time which would require a visit to the service repairman.

    Second step to problem resolution--rethread the machine. Remove the thread completely from the machine and start over from the beginning. Verify the thread path is correct.

    Also, using the correct needle type and size for the project is important. Don't use needles whose eyes are either too small or too large for the thread. Use a needle made for the type of fabric and project. Use embroidery needles when embroidering, use ball point needles for knits, use sharps (universal, microtex...) for woven fabrics, leather needles for leather, denim needles for denim/heavy fabric, etc.

    Last but NOT least, perform maintenance on your machine every 8 hours. Clean lint and loose threads from the bobbin area, the feed dogs, and under the needle plate. OIL (use good quality sewing machine oil) and apply just a drop or two every place according to the manual. Do NOT use 3-in-1 oil, cooking oil, motor oil, WD40 or any oil other than fresh, good quality sewing machine oil!
