Not sewing stich

When that happens, it is generally because it was not inserted correctly, and that's easy enough to do. Another possibility is the thread is not threaded properly
First, go to the Singer site and download your machine's manual -- it's free. A bobbin case has a flat part that goes under the needle. On the right side towards the bottom, it has a tab that sticks out that must rest against a spring, and prevents the case from spinning -- it must be stationary when sewing. When inserting a bobbin case, I find it helpful to put it down slightly to the right, then twist it so the flat part is under the needle, and the tab is resting against the spring. Also, verify that the case is even on all sides -- it's quite possible to insert it so that it's not resting flat in the basket (holds the case). You have to look closely to see it, though. There's drawings of it in your manual.

The first thing you need to do is check with your user's manual on to make sure that your needle is inserted correctly--flat side to the back, and it is all the way UP in the holder. I find a small needle nose pliers helpful to hold the needle for this. If you don't have it, you can download it free at the Singer Sewing machine website--I just did before I answered this.

Next, make sure you have correctly threaded your machine, and when you did so, the presser foot was UP (ALWAYS thread with the presser foot UP--on ANY machine anywhere!).

The next part is on page 20 of your user's manual, and there are drawings. Then, insert your bobbin, with the lever on the case DOWN (it's the only time you can insert and remove a bobbin; with the tab on the case open, the bobbin is locked into place. Make sure the bobbin is inserted the correct way. In your case, when you hold the bobbin up vertically the thread should be unwinding from the left, or clockwise. After you have inserted the bobbin, take a look at the right side of the bobbin case towards the top; you will see a slot the thread needs to go into. Once it's in the slot, hold your finger on the bobbin so it that can't unwind, and pull the thread so that it is in the slot at the top of the shot you put it in. This part exerts tension on the bobbin thread, and it's VERY important that you get it in there. . Then open the tab or lever and put it into the bobbin basket (holds the bobbin case), with the projecting part on the top. A length of bobbin thread should be projecting outside the case at this point--you will be drawing it up to the needle plate.

How, hold the top thread end pull the hand wheel TOWARDS you (ALWAYS towards you--on any machine) at least one revolution and possibly two revolutions, then pull on the top thread and the bobbin thread will come up. When starting to sew on fabric, hold your hand on the top thread for the first two or three stitches.

I can only give a general answer; you did not state what make and model you have.

Generally with bobbin cases, there is a flat part somewhere, as well as the "wings." The flat part goes under the needle, and at least one of those "wings" is designed to rest against something in the bobbin basket that holds it to prevent the case from rotating during sewing.

If you cannot find your user's manual that TELLS you how it's supposed to go in, you can generally get a replacement manual that you can download--either from the manufacturer itself, or there are a number of places that will provide one either for free or for a nominal charge.

Take a look at the bottom of page 62. It has instructions for cleaning your bobbin basket (it holds the bobbin case), as well as how to get the case back in. There is a projection on your case on the lower right; that projection MUST rest against what is called (and pictured there in the bottom drawing) the cushion spring. The top of the bobbin case that goes under the needle is the only flat part. When putting in the bobbin case (mine are very similar), I have found it helpful to insert it slightly counterclockwise of the spring, making sure the case is flat in the basket, then twist it counter clockwise so that the projection is against that spring. While your case is out, be sure to CLEAN that area thoroughly with a q-tip (I put a drop of sewing machine oil on the two ends of the swab to help pick up lint), taking care to get under the lip of the bobbin basket, where a lot of lint can accumulate, and then put ONLY one drop of sewing machine oil in the hook race and the center where it is indicated in the manual. After you have replaced the bobbin case but before you have put a bobbin in it, turn your hand wheel TOWARDS YOU (ALWAYS towards you, for anything) several times to distribute the drop of oil. The race is between the outside of the basket, and the metal hook surrounding the basket, and the indicated place is the only place (with the needle all the way up) where you can get a drop between them. It's also possible that lint or other debris--like pieces of threads--are preventing the case from seating correctly.

if upper thread correct, check bobbin is wound and inserted correctly. Pulling bobbin thread, the bobbin should turn counter clockwise. make sure thread is under bobbin case tension spring. With cover plate open hold needle thread and turn hand wheel towards you to see if hook picks up needle thread and passes it around bobbin case. if not check hook timing

Be sure your bobbin is inserted correctly. This is usually the main cause for the stitch not being made. If that's not the answer, be sure the upper threading is correct. If a thread guide is not threaded or if the thread does not go between the tension plates, this might cause your problem.And of course, make sure the needle is inserted with the groove toward you and that it is inserted completely in the needle channel. If none of these are the problem, the bobbin case may need to be adjusted or checked for burrs. I really hope this helps you. If it does, please come back to Fixya and rate my advice.

Hello

The bobbin might not be in the case just right, or the case not in the machine just right.

Remove the bobbin case and make sure the thread from the bobbin is feeding from the spool in a clock wise direction and through the guide on the side of the bobbin case.

Raise the needle to it's highest position and this will move the shuttle to it's proper position.

Lift the lever on the back of the bobbin case, with the arm on the case pointing toward the ceiling and slip into the shuttle.

Bend your head down and you will see the shuttle has a slot for the arm to fit into.

Once you get the feel for this you will not have to bend down for a bird's eye view!

Always thread a sewing machine with the presser foot up. Make sure the threading sequence is correct and the thread has not slipped out of the take up lever.

Hold onto the top thead end and lower then raise the needle to pull up the bobbin thread. Pull both threads under the presser foot and to the back of the machine.

You should now be able to sew without any issues.

check both upper & lower tensions
also check your needle to see if it's bent-roll on a flat surface to see if it rolls correctly
if the needle is blunt-it makes a popping sound when it penetrates the fabric
also check the bobbin area for lint & loose thread-some fabric produces more lint than others
make sure the bobbin isn't warped
make sure that the bobbin is correctly in the bobbin case & that the bobbin case is correctly inserted in the machine

first take off the needle plate and then tur n the handwheel toward you until the hook on the race is at the 1 o'clock postion then slide the bobbin case in you may have to work the handwheel back and forth to get it to slide in

Is the needle inserted correctly with the flat side at the rear and fully up into the holder ?

If yes, take off the needleplate, remove bobbin case and slowly rotate the handwheel towards you watching the relationship between needle, and the "hook" of the moving "race".

Set on wide zig zag........when the needle is fractionally past it's lowest point, and starting to rise, the hook should be level with the left side of the needle when on the right hand stitch of the zig...the eye of the needle will be below the hook, and ready for thread to be picked up for the stitch to form.

Any other result will mean your timing needs adjusting.
