angelren Report post Posted March 27, 2012 Hello, I have a Singer 29K51 sewing machine. Having loaded the bobbin, installed it in the shuttle, and closed the plate, I am having trouble getting the loop necessary for sewing which is created by the top thread and the bobbin thread. I have looked up pdf of the loading of the bobbin and shuttle and believe that I am doing it correctly. Can anyone give any trouble shooting suggestions? Thank you!

Wizcrafts Report post Posted March 27, 2012 Take some close-up photos of the needle and the uncovered bobbin inside the shuttle, with the needle down at bottom dead center. While the needlebar is down, shine a flashlight up from the bottom and look for a paddle shaped spring just above the needle mounting plate. This spring is responsible for keeping a little tension on the thread as the needle moves down, then ascends. This is what forms the loop. If that spring is bent, broken or missing, skipped stitches will be the norm. Quote Share this post Link to post Share on other sites
angelren Report post Posted March 28, 2012 (edited) Thanks for your response and taking the time to try to help. I have attached photos of the bobbin, shuttle, and needle in various positions in case I have made a mistake at any point along the way. I may be misunderstanding something basic. It's my first time using this type of machine and any and all help is greatly appreciated! The second to last photo shows a place on the top of the machine which broke off. I am unsure how much this may be contributing to the problem as it seems that the spring was designed to help vary the tension on the needle thread.

Wizcrafts Report post Posted March 28, 2012 It's hard to see the position of the pickup point with the needle down, due to poor focus. So, check it yourself. Rotate the handwheel towards you (the proper direction is counterclockwise) until the needle goes all the way down, then makes a slight upwards motion, then stop. Look at the pickup point on the bobbin case. It should just be crossing the needle, over the eye. As you continue rotating the wheel the needle will lift and the shuttle should revolve past the needle and about halfway around. Then, it revolves backwards until it stops about 1/4 inch behind the needle channel. If this defines what you see, the needle and shuttle are in time. If the shuttle reaches the needle to soon or too late, use a wide flatblade screwdriver through a hole on the front face of the base of the machine to turn the screw that adjusts the position of the shuttle. You'll need to rotate the wheel until the screw lines up with the hole in the base. There isn't a lot of range of adjustment. You haven't said anything about the condition of the thread check spring on the needlebar. It resides in a channel just above the needle mounting plate. The bottom of that spring is shaped like a paddle. If it is bent, broken or missing, skipped stitches ensue. Quote Share this post Link to post Share on other sites
