Grizz78 Report post Posted January 6, 2020 I am having issues with my chinese shoe patcher, the thread is balling up under the treadle. I have attached a couple pics to review. I have tried filing the edges and adjusting the thread tension. However, nothing seems to help. Any ideas or thoughts would be appreciated. patch1.jfif patch2.jfif Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted January 6, 2020 Either the shuttle timing is way off, or the bobbin tension is too tight, or the top tension is too loose, or the top tension release is opening the tension disks while you sew, or the machine is improperly threaded on top. Of these, I would investigate the bobbin first. Quote Share this post Link to post Share on other sites

Of these, I would investigate the bobbin first. I will address each of those tonight and let you know the outcome. Thanks for the input. Quote Share this post Link to post Share on other sites
Journeymen Report post Posted October 6, 2021 Hi Grizz, I started having this problem this morning when I switched to a thicker thread. Did you get it resolved? Quote Share this post Link to post Share on other sites
