Hi! Could someone help me with the uneven stitch lengths that I get while sewing leather bracelets (4mm thickness) on my Durkopp Adler 1180-511. This is a flatbed machine equipped with needle feed, lower wheel feed and top driven roller presser and clutch motor. I'm wondering if some transmission parts inside the machine can cause this. Please have a look at the attached image where you can see that some stitches are longer while others are shorter:

Great to hear that! Thank you so much for your help!

Thank you very much for your help! So if I understand it right, there is no difference in hole sizes between 134-35LR needle and 135-16LR needle?

Hello, I would like to know if the 134-35LR needle system makes smaller holes on leather than some other systems such as 135-16LR. For example, if we have the same needle size for both of the mentioned systems, will the 134-35 make smaller holes on leather? Thank you!
