TomG Report post Posted October 24, 2019 First, thanks for all the help earlier on my needle bar issue. I replaced it and checked timing and it looks OK, I think. But, I was sewing on a leash today for a repair and the stitching is for crap. I did not mess with bobbin tensions or top tensions during the repair. Sewing with 138 and 22 needle. Now, the leash is sort of soft, well-used VegTan. I adjusted the stitch length to use the old holes. My test piece was a lot better looking, but not 100% perfect. So, I guess the question is.. Can the quality and firmness of the leather affect the stitch quality in this way? Photo shows top side and bottom side. Quote Share this post Link to post Share on other sites
Dwight Report post Posted October 24, 2019 Your guess, . . . yes, . . . leather firmness and thickness can affect stitching that way. What is happening is your bobbin tension is too tight for the job you are doing. Tighten the top tension to pull the stitch up into the leather.

I THOUGHT I had that happening on my test sews after the repair. I'm going to breakout some good scrap and go back through all of the tension setup steps. That being said. I just discovered that both of the presser foot tensions were very light. I never thought to check those. The way my hands fed the 2 different pieces was different and I was probably holding the test piece down a bit without thinking about it. The leash was mainly making sure it fed straight :-) I'll know for sure shortly.. I do wish there was a way to precisely adjust the bobbin tension. With our 12 needle embroidery machines, we take the bobbin carrier out and hang 4 quarter taped together to the thread and bounce it. We adjust the tension until a bounce drops the stack and then stops. Easy-Peasy Quote Share this post Link to post Share on other sites
Dwight Report post Posted October 24, 2019 Not meaning to tell you how to run your rodeo, . . . but with my Tippmann Boss, . . . I learned a long time ago that the TOP tension is the one you can regulate, . . . can fix, . . . can work on, . . . and make things go good. Bobbin tension on it is a hit or miss, . . . maybe yes / maybe no, . . . type thing. But if I can keep it just close, . . . manipulating the tension on the top thread will just about always give me a good stitch on both sides. Best wishes.

You are not doing that at all. That's basically what I've been doing. I sort of pull the bobbin thread intil it "feels" right. and adjust my top tension from there. I was just blabbering about a "wish" <g>... 1 hour ago, Northmount said: Resewing through old holes throws off the tension settings versus new. Tom I thought that might have contributed. I haven't had a chance to play with it and do any fine tuning. Woke up sick this morning. Quote Share this post Link to post Share on other sites
