Sorry, the machine used in both photos is the Juki LU-563. I have tried several different types of thread, size, brand, ect. With no real improvement. (Although some were definitely much worse) as well as new needles in diffrent sizes. Although I do sew a large variety of things, my typical set up consists of 1. the Juki LU-563 2. size 18 or 20 organ needles (depending on material) 3. size T-90 weight UV bonded polyester thread (A&E, though I've used sunguard and Tenara) 4. Sewing marine grade Sunbrella or Weather Max canvas And this is an issue that has gone on for many years. (I've been sewing professionally for 30 years now) It doesn't happen often enough to really cause too much concern, and even when it does the top thread becomes "tied in" enough that it really doesn't affect the strength of the stitch. It's more of one of those little annoying things that I've been meaning to try and really figure out for a while now. Thanks for the suggestions (I didn't know about the #1 adjustment to the check spring) and for any future suggestions anyone might give.

I also caught it in the middle one time and this is what the bobbin looked like. Is it a random gremlin? Or is there something I can adjust? PS. It's happened to me on a few diffrent machines. (Juki LU-563, Consew 206)

I've actually been having this problem for quite a while. It doesn't happen all the time, just kind of randomly. I'll be sewing and in the middle of a stitch the top thread will catch, then break on the bobbin. The machine will then just continue sewing like normal. This doesn't happen at the beginning or end of a stitch. It's literally in the middle and I can usually hear it snap when it happens. I've tried multiple tension adjustments and switching out needles, diffrent size threads and needle sizes. AND I've had this happen on multiple machines. (Again not an every day thing, but it can happen several times in a row then miraculously go away for a week or two) Also, I can't seem to reproduce it.

Finally bit the bullet and bought a servo with synchronizer for my Consew 226. The motor installed fine and is running good (except it tends to roll backwards at the end of a stitch, but I increased the brake all the way and that seemed to help a bit) the problems started when I went to install the synchronizer. The instructions are horrible but I have a good basic idea of what (I think) it's supposed to go on like. The biggest problem is that the was no bolt on the end of my machine's handwheel. There was, however, a tapped hole. Except none of the bolts that came with the synchronizer work. They are all too big. I'm about to go to the store to see if I can get another bolt that might fit the threads that ARE in my machine, but I'm worried about the bolt being too small then for the connector that I'm trying to bolt on. I'm worried it might slip. Any advice? To give more info, I have a used Consew 226 that came out of a Lazy Boy furniture factory, and a Mophorn servo with synchronizer (looks like all the other China made servos out there) I'm attaching photos of the handwheel of my machine, and the contents of the synchronizer package. There are also a few things that came with the synchronizer that I'm not sure what they would be for. Maybe they can help with my machine, I'm not sure. Thanks for any advice you can give. I guess if all else fails I can just run it without the synchronizer.

I've been sewing on industrial machines for more than 15 years now. And although I'm getting pretty good at repairing most things that go wrong with my machine, it has been a long trial and error process. There's only one person in my area that services industrial machines and if mine breaks down, it can sometimes be a while until I can get him over to my place to fix it. I'm wondering if anyone has any suggestions on repair manuals or anything that would help me to learn how to repair my machine myself. I mostly want to learn about my industrial machines, but I would like to learn how to repair my home machine and sergers as well. I have a Consew 226, Juki LU563, Singer 31-15, as well as a 5-thread and 4-thread sergers (non-industrial), computerized home machine, embroidery machine, and a few, not used too often, treadle machines. Thanks so much for the help. It would be great to not have to be down for a few days while I wait for my machine to be fixed. (customers don't like it either ) Thanks, Jaunvie

Looking for an adjustable quilting guide that attaches to the foot of a juki LU-563 industrial walking foot machine. Can't find one anywhere. Any ideas?
