    How to use my Antique Singer 112W139

    Trying to solve problems with my sewing machine
  1. Mine only releases at the "second" lifting position.
  2. OK, I started over, setting my bobbin tensions very light and trying to get them even. Then I backed off the upper thread tension and went back to threading like the manual directed (trying to thread them over the little posts was very difficult anyway). My stitches look much better and more even now. I think I am there now. The only problem left is getting the threads to release from the hooks at the end of a stitch (I have to rock the hand wheel back and forth sometimes), but that might be just the nature of the beast.
  3. Still having trouble getting enough tension on the upper thread. Has anybody used the "threading a double needle walking foot sewing machine the right way" by Moose Trading in witch he threads the two tension disks by going around the little posts (not what my manual says). Here is what I am getting now on two layers of vinyl using the Moose Trading upper threading and I have the tension screws pretty tight.
  4. Strangely enough, the large amount of slack below the thread controller seems to have gone away, so I locked down the controller setting. I made a video, but I can't seem to make it small enough to attach it, but it just shows everything working right. Thank god for this forum and for you, Uwe and Brmax.
  5. Brmax, I live in a small Oklahoma town and we had sew machine repair shop a few years ago, but I guess he retired. Uwe, actually I have the threading right as far as your video shows, but I still have more slack even with the large movement of the thread controller. I will post a better picture below. The trick of holding tension of the upper threads seems to have solved the binding up the rats nest down below. Now, I can work on the tensions of the upper threads. Later today, I'll try to get my son to make a video of the slack left by the thread controller.
  6. First of all there are no sewing machine mechanics in the area (I wish there were). I also realized that the hook gear set screws were not in the groove on the shaft, and have corrected that. Here are a couple pictures of the timing control: As I turn over the hand wheel to make a couple of stitches, I get about 2 turns and the machine locks up with a tangled mess. Here is a shot of the mess.
  7. I'll try to do that (but I don't know how to attach a picture or video to a post), but something even more weird just happened. When double checking my timing, I found the right hand hook assembly was almost 180 degrees off. Thinking I had made a mistake, I corrected it and made sure the two hooks were in sync. I then tried a couple of stitches which resulted in a rats nest under the stitch and a tangle of threads caught down in the machine. I just got it untangled and unbelievably the right hook assembly is again 180 degrees off. How can that happen?
  8. Thank you for the reply, but unfortunately or fortunately, I was doing it correctly. So my original problems still stand. I have moved the lower stop as far down as it will go, and turned the tension back and forth and as I said, too much tension and it won't reach high enough and too little and it won't return to the lower stop. I have felt the spring movement and it seems to move freely. I was unsure if the outer part of the spring belonged on the outside of the "disc" since I had taken all apart, but your excellent video clearly shows that I had reassembled it correctly. In trying to get this machine working correctly I had to readjust the stitch length to match the numbers, which somehow, screwed my original timing, so I had to re time it again and now I think I have it just a little early but again, I want to solve this loose thread controller problem. In all the videos I have watched of similar machine running, none of them seem to exhibit as much loose thread as I have. Maybe that is not my problem. I don't have enough strength to lift the machine straight up out of the hole in the table, as I don't yet have the female parts of the hinges so I have to keep calling my son every time I need to work on the underside of the machine. I can't believe this thing is so heavy. No wonder Singer called my old 306K a "featherweight".
  9. I recently purchased a used Singer double needle 112W139. I have a manual for the machine and have timed it successfully, I believe, but have a few problems I can't seem to solve. First I can't get the thread controller to work properly. No matter how I adjust it, it leaves too much slack. I have moved the stop as low as it will go and turned the controller back and forth for tension. Too much and it will not let the spring move to the top and too little and it not return to the bottom, and at the best compromise it leaves so much slack that the thread sometimes actually come out of the lowest guide just above the needle. I have alternately thread it by the manual, and tried some of the "right way to thread a double needle machine" found on the internet. Nothing seems to help. I also have trouble with picking up the bobbin thread, but until I solve the slack in the upper thread, I don't want to tackle 2 problems at the same time.
