Members broncopeters Posted October 8, 2020 Members Report Posted October 8, 2020 Hey everyone, I'm new here and psyched for all the info everyone provides! Thanks. I just acquired a Cobra Class 26 and am having trouble with the tension using 138 thread. The bottom stitch doesn't seat and the knot shows on bottom. Does this mean that the top tensioner needs more tension? Also the bobbin tension is not tight, but doesn't just give off slack super easily, should it also be backed off? Coincidentally, 207 thread works like a dream and looks perfect. Thanks in advance! Cheers, Quote
Members Hildebrand Posted October 8, 2020 Members Report Posted October 8, 2020 No tension expert here but it sounds like you need more top tension. 138 is smaller than 207 so it will not have as much resistance at the current settings. I would leave the bottom the way it is and adjust the top, if you end up needing more then you can adjust the bottom to be slightly less tension. Todd Quote
Moderator Wizcrafts Posted October 9, 2020 Moderator Report Posted October 9, 2020 If you aren't already doing so, use a #23 needle with #138 thread, top and bottom. Quote
