Tighten the bottom thread or loosen the top thread a little. There should be a little screw on the bobbin holder where you can adjust bottom thread tension.

My machine flashes C4 when i want to sew


Clean the bobbin case area thoroughly, and probably the feed dogs, too. Start all seams by holding the top and bobbin thread ends together behind the presser foot for the first few stitches. If you have lost your manual, pick up a new one, free, at http://www.singerco.com

Hi I have a Janome 419S or 423S, the problem seems to be my hook race unit keeps getting loose and then the thread jams up. What can be done? Please


A jammed machine is caused by thread being caught in thehook. Remove the upper thread and the bobbin case, turn the hand wheel towardsyou (counterclockwise) by hand and remove any thread in the bobbin case area. Alwaysturn the hand wheel towards you. Turning the hand wheel away from you(clockwise) can cause the machines timing to become unaligned and jam yourmachine. Also, always make sure the presser foot is in the down position beforeyou start sewing. Sewing with the presser foot in the up position will jam yourmachine in the bobbin case. If youhave an older model sewing machine with a shuttle hook, then you can alsofollow these: 1. Disconnect the sewing machine from any power source.Loosen the thumb screw on the left side of the sewing machine body and removethe cover to expose the needle bar. This is the shaft that extends down andthat you attach a needle to for sewing. Open the shuttle race and remove the bobbinand bobbin case. 2. Turn the hand wheel toward you until the needle hasreached the lowest point of the stroke. The hook should be at the top of itsstroke inside the shuttle race. Loosen the set screw for the needle bar on theupper part of the machine, this is located on the needle bar bushing (thecollar that the needle bar slides through when making a stitch). The needle barshould slide easily up and down. 3. Turning the wheel again, adjust the position of the tipof the needle so that the upper part of the needle eye is just below the bottomedge of the hook inside the shuttle race. Once in position, re-tighten the setscrew on the needle bar bushing. Do not allow the needle bar to slip whiledoing this. 4. Replace the bobbin and bobbin case and close the shuttlerace. Thread and plug in your machine. Using a sizable scrap of cloth, sew aseam to check to see if there are any skips in the stitching. If there arestill skips re-adjust the timing again until you can sew without any skipped stitches. 5. When proper timing has been achieved replaces the coveron the needle bar and tighten the thumb screw. Hope this will help you. Good Luck.

What is the difference between a sewing machine and a serger?


Well..... A serger (or overlock) sews a different, and usually more complex stitch. Where a sewing machine usually only uses two threads to make the stitch, a serger can use two, three, four or even five threads and will sew around the edges of the work piece, as well as trimming the edge of the work just ahead of the sewing area, or as you feed the work in, the trimming takes place first. Sergers also make a stronger seam, attributable to more thread / stitching in the seam. Sergers are versatile and quick, but one drawback is the fact that sergers make a chain stitch instead of a lock stitch, like a machine with a bobbin, and lock stitches can be pulled out, like the stitching that used to close dog food bags and bags of charcoal. A lock stitch is just what it sounds like, it can't be pulled out. You only get a lock stitch with a machine that uses a bobbin, and sergers don't use bobbins. That fact makes serging desirable for the speed of production. Changing bobbins takes up a lot of time, even if you are using pre-wounds. Hope this helps!

The tension of the thread on top and bottom is not equal. How do you adjust the bottom thread to make it equal to the top?


Hello

First locate the sewing machine tension gauge. Sometimes its called a knob or a button or found on your Touch Screen if you have a computerized machine. Refer to your manual if you can't find it.

Either your needle thread is too tight or your bobbin thread is too loose.

First check that your bobbin thread hasn't slipped out of its tension spring in the bobbin case.

If the bobbin thread is correctly threaded through the tension spring, then decrease your needle tension by 1 number. Test by stitching several inches on your small quilt sandwich. Keep decreasing the tension until no needle thread is visible on the quilt top.

If sewing machine tension problems occur during the middle of a quilting session, again, first refer to the checklist above. Once you're satisfied that your sewing machine is threaded properly and your needle is not the culprit, then adjust the tension as outlined above.

If you have just started testing your quilting thread choices and you are using different threads for the needle and bobbin, you will in all probability make adjustments to your tension.

Make a small quilt sandwich from the materials used in your quilt to make this sandwich. It doesn't have to be pretty or even pin basted. It should be just big enough to test some of the stitching you plan to do on your quilt.

Jc penny model 1710 sewing machine, the stitching isnt tight


You do not say if it is the top stitches or the bottom stitches for the bottom tension, check that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder. The bobbin tension adjustment is the small screw in the plate on the bobbin case that the thread passes under as it comes off the bobbin and goes out.
For the top stitch, tighten up on the tension adjustment on the front of the machine which looks something like this:-

I have a Janome 8048. Here's my problem: As I sew I notice that the stitches on the top of the fabric look the way they should on the bottom side and when I take the material off the machine and flip it...


I haven't sewn in years. A sewing machine has a tension control on top and on the bobbin. If the intersection of the top and bottom threads is not in the middle of the sewn material, you have to adjust your tension.
In your case, what I think you are saying is that the stitch on top is just a straight line and on the back it disappears into the fabric.
To correct this, lower the top tension by loosening the tension adjuster on the thread where the thread loops around the small pulley.
Also, you could tighten the tension on the bobbin by slightly tightening the small screw on the side of the bobbin.

I have a model 605d ,the machine work fine except it will not sew! i look over the machine it look ok ! i am found out that top spool thread and the bottom bobbin thread are not coming together to sew!


You have to do the first stitch using the handwheel so that the top thread catches under the bobbin thread and then you can pull the top thread which will bring up the bobbin thread. put both threads to back of machine. Now you can sew.

Every time you re-thread you need to do this.
