    Brilliant! I'm just in awe of how these machines all work together and of the person/people who worked all the mechanical movements and adjustments out to achieve a lock stitch from just turning a crank handle. These machines literally "revolutionised" stitching.

    Thank you very much for these videos. They are very helpful and informative.
    I'm very happy with my machines performance. but I would like to
    try to get my patcher to sew a little thicker thread with out fraying
    and knotting up and braking the top thread. Seeing through your
    transparent shuttle bed cover I can see what is happening.
    (I'm using a135x16LR grooved needle plus the thicker thread)
    Therefore running out of room. I think by
    making the needle hole a little bigger may solve my problem.

    I had quiet a bit of trouble with my machine picking up the bobbin thread. There were problems with various part not being in sync...such as the handle not being in right place when the bobbin was a certain position and the cam not being where it should be. After many many attempts I finally was successful in picking up the bobbin thread but it was exhausting. I am marking all moving parts with position scratches just in case it have to remove some part for some reason. I do appreciate this video because it gives me another tool to get more perspective on how the machine works. Please continue to make more videos they are helpful. THANKS

      This is the purpose of making this video : let users know the steps how stitches formed and through the process they would also learn the structure and mechanism of the machine. Then any issue related to the bobbin would no longer be a trouble for them. The initial setbacks in using the machine you suffered is also the story of me and many. Your insistence to overcome the problems saved the machine from being treated as a "crap".

I have slightly bored the hole and the helped. But I cannot seem to get my needle to lock the stitches. Timing of bobbin is same as yours though I will double check.

      If you mean bobbin drive gears are those immediately under the bobbin, then just put a few drops of lubrication onto them. If you mean the rod moving the bobbin, then a few drops of lubrication onto the areas you can touch.

    Okay, it's my fault that I can't dependably get my machine to work. In trying to figure it out, it appears that there is super critical timing issue that requires the shuttle carrier to be inserted at just the right position to engage the teeth of the reciprocating bar down below. I'm not sure I have it right now but I am close since it will stitch most of the time, but I still get binding, usually of the top thread being stuck in the bobbin compartment. A video that explicitly shows the correct installation of the shuttle carrier would be great. After that, everything else seems to be fairly straight foward, although tensioning the bobbin and top thread is also a bit tricky and has required a lot of trial and error. Great video though.

    • @kslam5733
      @kslam5733  5 лет назад

      Your experience in using the machine was also true to me. This machine needs some adjustments and users need learning some basic skills before any success. As skills accumulated, users would find the machine a very useful DIY tool. This is the reason why I like to share what I have learned using the machine in refurbishing, repairing and making things. It is hoped that users' negative views when using it in the beginning would not last long. For timing issue,I have another video on it. Search RUclips for it.

    • @kslam5733
      @kslam5733  4 года назад

      The origin of the prototype of this patcher was unknown but may be from Europe in the 19th century. The popular use of it began in the post war China in 1949 when China needed to develop on her own in face of the US containment. The containment made China suffer from inadequacies in everything especially daily necessities. Chinese people needed to wear clothes and shoes even though they were broken. The patchers were then put to use for this purpose. These patchers were expensive during that time. People tried to produce them in their backyards at nights believing that they would get rich by selling them. They dared not produce them openly in day time because they were not allowed during that time. Also many people tried to buy one to be cobblers in the streets. They could earn a living by that tool. As producing them was so difficult the patcher was rough both in outlook and the materials. The patchers then remain rough even up to nowadays as they were designed for the professionals with no user friendly settings and streamlined body.
      The patchers were quite a useful patching machine for the street cobblers since the 1940s. They could be found almost in every city in China in the 1970s, 80s, 90s and even the 2000s. However when China reformed herself in the 1980s and people getting wealthy in the 2000s, the patchers were gradually phased out from the streets.
      Surprisingly the machine is now quite acceptable to other countries rather than China herself. Chinese people do not like to own such a museum item in their home where spaces are quite limited. They get used to buy things when broken rather than letting the street cobblers to mend them.

    Great video. I recently purchased one of these and have most of the adjustments worked out. I am still experiencing some skipped stitches and not sure why. Not sure where the failure is in the 3 point turn, than obviously needle thread or bobbin thread missed the connection. Will you share your thoughts on this?

    • @kslam5733
      @kslam5733  5 лет назад +2

      Check the path the thread runs from the thread spool to the needle. Any obstacles would tighten the thread from forming the loop for the bobbin hook to grab. A skipped stitch would form. The correct routing of the thread is also important. Check from the file section of the Facebook group "China leather shoe patcher" for more details. You can also raise your questions there. Join them as a member and you would have lots of helping hands.

      Indeed I have thought about that putting a split screen showing the crank wheel movement. However, in doing so the shots on the bobbin movement would be reduced in size. I then simplified the crank wheel movement views to just a wheel with animated arrows showing the 3 steps positions. Thanks for your suggestions.

    I just about pulled my hair out for the last hour following this video and others to get the needle to thread. I just discovered it was because my needle was slightly bent the Bob And couldn’t catch the thread. Make sure your needles straight.

    • @kslam5733
      @kslam5733  5 лет назад +2

      Thanks for watching. The working principle is when the needle pierces into the fabrics, thread turns to be U shaped via the needle eye. On one side, thread gets into the needle groove; on the other side where no groove but a scarf, thread also being straightened. Then when needle withdraws from the fabrics, friction with the fabrics creates a thread loop on the scarf side. If the needle position is wrong, the shuttle hook would not grab it.

    • @kslam5733
      @kslam5733  Год назад

      Do you mean the iron flat plate on top of the bar? the hole comes with the plate because the plate can be used both sides, it is for fitting onto the extrude point for fixing the plate. My bobbins do not have holes on them. If there is, it is for easy threading of the bobbin.

So watch a few videos on you tube there is a lot of info on problems and ways to correct them Good luck .

    • @kslam5733
      @kslam5733  3 года назад

      The snapping of thread especially the upper thread would definitely happen if no polishing done to areas the thread goes through. So check every inch the thread comes into contact and polishing them. Watch out especially the bobbin case, the edges and the small hole the bobbin thread goes through. Also the path the upper thread runs through such as any twists formed and jammed inside the tensioner, any obstacle happened in any corner passing through, thread size is suitable for the needle (too thick would not go through the needle eye smoothly and would snap).... If problem still exists, make a transparent plastic cover like my example in the video to find out how and when it happened. It is not difficult to find out as it is just a simple machine.

      Not fully understand the text translated. The thickness of the threat depends on what you want to sew. From my experience, use good quality and not too thin thread is the golden rule. The thread needs to pass through many edges of the machine, It is easy to break. You also need to use proper size of needle and right thickness of thread, they need to match. All these should be learned through practices by yourself.
