chiefjason Report post Posted January 14, 2014 Details- used BOSS 1, about 10 years old. 346 thread and appropriate needle. 2 layers of 8-9 oz leather. I am really trying to get this machine up and running, and like it. But it's just not going well. Good thing it's on loan instead of paid for yet. I was stitching in a mouth reinforcement for a holster. As said, 2 layers of 8-9 oz leather. Top stitches looked good. I would get an occasional grab or catch on the up swing of the handle. First try had several loops on the bottom side that were sticking off the leather. After taking the thread out I realized it was the top thread that had looped and not pulled tight. Second try, I was able to see the thread catch on the tension adjuster screw. I could stop my stitching and manually pull the thread up and get the right seating on the knot. But I had to feel it catch in order to stop. Good news, I kind of know what is going on. Bad news, how to fix it? Is it as simple as tightening the screw some? Seems that will throw off the tension that seems to be pretty good right now. Tighten top and bottom? Or is this one of those quirks I'll have to get used too? Top stitch looks good on the second try. Bottom stitch looks OK, with a couple bumps. But stitches on the inside of the holster always look worse IMO. But that first run with the loops had to be removed and re stitched. Like I said, I want to like this machine and get it working. Just having trouble dedicating the time to it. Especially when so much of that time seems to be trouble shooting. Thanks. Quote Share this post Link to post Share on other sites
Anne Bonnys Locker Report post Posted January 14, 2014 Always start with the basics. Is the top end threaded correctly? New needle inserted correctly? Right size needle? Bobbin in the right way? Is your bobbin smoothly wound? Damage to the bobbins? Is the thread feeding freely? Next step is to have a closer look at parts: Any roughness on the shutle? Strip off the tension discs and look for damage to plates or post? Quote Share this post Link to post Share on other sites
neelsaddlery Report post Posted January 14, 2014 On the Tippmann and machines like it if the bobbin thread tension is too loose the thread can hang on the tension plate that goes on the bobbin case. I have seen this many times when tension plate us too loose. Try tightening screw a bit and see if this helps. You can alsoswitch to next size smaller thread in bobbin. This should let you tighten screw a bit more. Check to make sure top of machine is threaded right and tension disks are threaded right. This makes a huge difference.

I have seen this many times when tension plate us too loose. Seems it may have been that simple. Turned down the tension screw on the bobbin. Turned the top down a bit to compensate. Stitched 2 double mag holders without a problem. Things are looking up. Thanks. Quote Share this post Link to post Share on other sites
Troy Burch Report post Posted January 15, 2014 That's good news! I got so frustrated with my 5 year old Tippmann I bought an Adler about a month ago. I haven't tried to sell it because I didn't want to screw anyone over. That's the exact same problem I've been having, going to try that tomorrow, maybe I can sell it after all. I was very happy with it until then. Thanks Troy Quote Share this post Link to post Share on other sites
chiefjason Report post Posted January 17, 2014 Troy, on more than one occasion I have nearly thrown it into the front yard. And I think that little screw was most of my problem. I need to stitch a holster with it. I do mine very non traditional. If I can do that, I'll probably be buying it. Quote Share this post Link to post Share on other sites
