Thompson PW 103-A-GBP

I have a Thompson PW 103-A-GBP. It has a flat curved metal piece that has something to do with releasing the tension. It is broken. Where can I find parts for this machine. I also need a manual for it. Thank you if anybody can help.

SOURCE: I have a Thompson PW 201 machine . It will not

it sounds like to me that the timing is off, check to see how close the needle is to hitting the bobbin when it comes down through the table. that metalic clunk is probably the needle hitting the bobbin holder, OR the bobbin.. check for a bent needle also..

Where should upper tension be to start out with a thompson mini walking foot pw201?


I'd want to check to be sure the thread is not getting caught on anything, which can mimic upper tension issues. Check the thread path, all the guides, the spool pin, the take up lever and needle bar, for nicks or wrapped up thread.

Tension discs can wear out with age. I'd try cleaning them, fold a thin pieces of soft cloth and gently work it between the discs. Should remove anything stuck in there. Just a touch of one of the silicone thread lube products may be helpful. I'd apply it to a piece of thread and then work the thread through the discs, rather than apply the lube directly to the discs.

Walking feet themselves usually don't need anything special in terms of tension. But you do need to be able to sew a balanced stitch.

Using a thread coloured differently for bobbin and top helps you see if it's balanced. All one colour on top, all the other colour on the bottom, is what you want to see. If you see pops of the other colour on top or bottom, there's a problem. If you see the bottom thread on top, or vice versa, there's a tension problem.

Thread damaged by an burr in the needle eye can fray and mimic upper tension issues too. I always try replacing the needle with a brand new one, which sometimes fixes all sorts of things. Brand new is best, not just another needle.

If none of this helps, then you may be looking at needing a new tension mechanism, or rebuilding the one you have. Best of luck.

I have a juki 9000, we were having tension issues but have finally gotten the perfect straight stitch. But when going around corners the top thread pulls to the bottom and gives that pulled look instead of...


As a rule, it is because there is less tension on the upper thread from a couple things:
1, the material on the curve is thicker and the foot is pushed higher in the air as it rounds the corner. When it is pushed higher in the air, it automatically opens the tension slightly and lets more thread through. I especially have that problem if I have cording on that curve.
2. something that I have a problem doing myself is that my knee is on the knee lift slightly, trying to help me get a smooth curve. When I do that, it does the same thing as above; it releases the tension just enough to give you too much thread and the stitch pulls to the bottom,
Just some possibilities:
1.)I have had some success by making my stitches shorter, pressing the curve flat with steam if necessary, using a narrower two toe foot (zipper foot generally doesn't have enough pressure to hold it down while I am sewing the curve).
2.)I have tried a Teflon foot on thin fabric with lighter foot pressure. 3.)Possibly a size needle that is one size larger than the one you are using now or a thread that is slightly lighter weight or smoother.
4.) Its awkward but if you can only use your left hand to guide your material around the curve (and it works really well once your practice. My friend used to make shoes and taught me this years ago), then use the index finger of your right hand to put a slight pressure on the tread as it comes down to the needle bar when you are going around the curve, you may be able to make up for the release of the tension discs.
Good Luck!

How do you tighten the tension where the bobbin is ?


Ther is a small opening where the thread comes out of the bobbin and a flat piece of metal right there, you need to check to see if the thread goes through it and out, or if it might be broken off. looks like a flat piece of metal and is actually a spring for drag on the thread. some machine have it where the bobbin frame rotates a little to adjust it. hope this helped

Tension loose


When you raise the presser bar it should lift a small U-shaped piece of metal inside the head of the machine directly pushing a release pin located in the center of the tension post. You have to determine whether this operation is happening before you go any further. Sometimes the screw on the lifter bar loosens and loses contact with that U-shaped piece of metal. If that is working properly, then on your tension unit itself, starting with the parts going from front to back, you have a thumb screw, a number wheel, a lock, a beehive-shaped spring, and the next piece is the tension release cup. This cup slides on the tension bar with the piece of metal sliding into the bar which is split. That slight peice of metal that slides inside could be deformed. If that is the case, tap it gently to bend it towards the machine. This is the best that I can tell you right now.
