bootswithjay Report post Posted June 22, 2021 I recently acquired a 52w22 post stitcher. I am struggling to really figure out how to get it all working. Every time I go to stitch, I end up with bunching on the bottom side of the leather or a knot near the bobbin. Does anyone have a resource that can help with threading and tensioning this particular machine or one similar? Quote Share this post Link to post Share on other sites
Constabulary Report post Posted June 22, 2021 Please post pictures of your threaded machine so maybe we can see if something is wrong. There are 2 types of 52w. THis manual is for the earlier type. Maybe it helps Singer 51w100 and 52w100 - instructions for using and adjusting.pdf Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted June 22, 2021 Generally speaking, thread knots on the bottom means excessive bobbin tension, inadequate top tension, a needle that is too small, or the top thread is not fully seated in the top tension disks, or the disks are not fully closing as you sew. Pick one and run with it. Quote Share this post Link to post Share on other sites

LindanHotAir Report post Posted June 23, 2021 On the side of the bobbin case there is a flat spring. There are 2 screws through the spring. One attaches the spring to the case, and the other screw adjusts the bobbin thread tension. Turning it slightly clockwise increases tension. Quote Share this post Link to post Share on other sites
