Question about Sewing Machines
Hello, I've got a brand new Toyota sewing machine. Model: SP100. I already have sown a vitrage, which went very well. But now I'd like to sow a zipper onto a coat. I already made two attempts, but both times the coat's fabric could not be transported by the pressure foot (under the sewing machine's needle). I think the pressure of the small foot upon the coat is too high. The Toyota SP 100 has no adjustable foot pressure button, as far as I know. But it really should be able to sow through twelve layers of fabric, as Toyota advertises, so it certainly should be able to sow a zipper onto a coat. But I don't know how to lower the sowing foot pressure, I can't find the answer in the manual, or by googling on the internet. Can you help me? Thanks! Berend de Groot.
Berend: Thick fabrics require a longer stitch length. If the longer stitch length doesn't work check your attachments for an Easy Feed foot (It sort of mimics a walking foot.)

make sure your needle is facing the right way, some needles if you look at the front and back you will see a groove side and a flat side sometimes it is hard to tell the difference depending on needle style.. hold it up to light and look at it from the side the difference will be slight but you will see a difference groove should face the back or if your presser foot is out of wack (lol so technical terminology) it could cause needle breaks and noise you can detect damage to the presser foot if this is happening.... only other thing i can suggest is to make sure bobbin is securely snapped into the housing if not it can cause problems with the needle picking up the bobbin

The timing needs to be adjusted and this is best done by a sewing machine repair person.
You can get directions at the website for sewusa under repairs.

SOURCE: The thread is bunching up
Your problem stems from the faulty foot lever mechanism. It's coupled to the upper thread tension control which only provides tension when the presser foot is in the locked down position.
If the presser foot won't positively engage in the down position, there's no upper thread tension and the thread bunches up below. Everything else stems from there. If the needle has hit the bobbin case too frequently then the bobbin timing may also be slightly out and the needle itself will be damaged and won't pass straight through the fabric; it only takes a tiny deflection from the vertical as it passes through the workpiece for the needle to flex and hit the bobbin case.
In summary, your machine is in desperate need of repair and adjustment. You haven't stated which exact Singer model you have, but they are usually easy to get servicing manuals for or you can take the machine to a sewing machine servicing specialist. Most singer spare parts (even for 100 year old machines) are usually still available fairly cheaply from a variety of sources, just enter "Singer spares" into your search engine to find suppliers.
To prevent re-occurrence, clean the mechanism regularly and lubricate it as directed by the manufacturer using sewing machine oil. Depending on how often you use the machine, do (or have done) a more thorough service periodically to check the timing and also that all mechanism screws remain tightly fastened.
I hope that my reply has shed some light on your problem and enables you to decide what to do next. Please take a moment to rate my answer.
