tjkarmin Report post Posted August 3, 2015 Hi! I recently bought a new Tacsew T111-155 machine with a Servo motor. I tested it out with 138 weight bonded nylon thread and 135x16 size 20 TRI needles. I'm having issues going over 5mm of leather seam. It skips stitches right before the seam. Also it seems like the 138 is way too heavy for the leather which is about 2mm thick. Would 69 be too thin??? Quote Share this post Link to post Share on other sites
CowboyBob Report post Posted August 3, 2015 Try a #22 needle,20 is too small.You also might need to tighten the foot pressure down more,this is the knob on the leftside on top of the machine. Quote Share this post Link to post Share on other sites
