toxo Report post Posted 8 hours ago (edited) Wanted to make a cover for one of my knives but this is the first time I've asked my new machine to sew some thickness and I can't get it right. This is hard thick veg tan and I'm wondering if I'm asking too much of it. Top looks ok but I can't get the bottom to match. Apologies for the bad pics. Had to downgrade them to get them all on. This is softer leather. Not perfect but better. Tension discs and using 20s thread and a 120 needle. Have adjusted top and bottom tensions . Have lowered the check spring. Am I missing something?

Constabulary Report post Posted 5 hours ago I cannot see how good or bad the stitches are, pics are too small but when I sew NM 20 thread I´m using a larger needle size like NM 140. Quote Share this post Link to post Share on other sites

The thickness to don't think is the problem I think it has more to do with you needle thread size combination. 2 hours ago, toxo said: Tension discs and using 20s thread and a 120 needle. If I am reading the label on the thread correctly it is metric 20 size which is V138 thread. The metric 120 which is a size #19 needle is for metric 30 which is v92 thread. The correct size of needle needs to be a minimum of 140 metric (#22) and max 180 metric (#24) in real thick stuff. The needle hole made in the leather has to be large enough to basically accommodate 3 strands of thread, the top thread strand and the two strands of bobbin thread on either side of the top thread forming the loop. kgg Quote Share this post Link to post Share on other sites

Moved your post to leather sewing machines. That can't be right can it? I normally keep 600 across the top but was too much for these. I had to go down to 300 for these, crop more and decreased the resolution from 90 down to 60. Maybe I overdid it. The limit is still 1.47 Megapixels right?
