quiltiste Posted June 29, 2010 Author Report Share Posted June 29, 2010 Hello there, I've got one of those projects from hell that is keeping me up at night and I am hoping someone has some ideas! I have already tried every tip I can find in the manual and on the forum for thread breakage problems. I am using Aurifil 50 wt thread on top and bottom line prewound bobbins on the bottom. This has never been a problem before, but for some reason it's a problem now! My top thread keeps breaking. IIt stitches fine for a good 10 minutes or more sometimes and then breaks with a pretty clean slice. Sometimes it seems like it happens at a seam, and other times it's just random. I am doing very dense stitching, and I don't know if this matters. I have tried: -Change needle (several times) -Check for burrs on hook, file down with emory board -Oil bobbin case and other oil points -Clean and blow out bobbin -Rethread -Loosen top tension -Slow down my speed of quilting What else is there to check? I have broken a needle before, but I have very carefully filed everything down. I am ordering a new hook assembly tomorrow if I can't find a solution. I've gotta get this quilt done like YESTERDAY so I am really hoping I don't have to do that and then mess with all of the re-timing. I don't know what else to do, I am about to break down and lose it! Thanks so much, I really appreciate any help that anyone can offer! Link to comment Share on other sites More sharing options...

Busy Quilting Posted June 29, 2010 Report Share Posted June 29, 2010 Have you tried a different cone of thread? Turned the cone up the other way? Sewers Aid on the cone? A bigger needle? Lyn Link to comment Share on other sites More sharing options...

LinneaMarie Posted June 29, 2010 Report Share Posted June 29, 2010 Sounds like a bad spool. Have you tried it on your DSM? Also, loosen the bobbin maybe? I'm not sure, just throwing out things here. I think the BL is too strong for the Aurifil. Good luck, and hopefully an expert will chime in!!;) Link to comment Share on other sites More sharing options...

Quilting Heidi Posted June 29, 2010 Report Share Posted June 29, 2010 I would try sewers aid and see if that helps. If you have another spool of the same thread try that and see if it makes a difference. Also check the cone to make sure there isn't a burr on it.

ffq-lar Posted June 29, 2010 Report Share Posted June 29, 2010 When the thread breaks, take the end and bring it down to the eye of the needle. If the thread is breaking before the needle, you are catching on something above the needle plate. It's either a burr/groove on a pigtail guide, a bad needle, or a burr on the hole in the needle plate. Or if the top thread is loose, it can fling out and catch on a screw head or wrap around another part and snap. If it is breaking below the needle plate, there is something rough on the hook still and use a magnifying glass and your fingers to find the rough spot. If you have fiddled with your timing recently, check that the hook retaining finger is positioned properly. If it is pushed in too far, it can catch (squeeze) the bobbin thread and the bobbin thread will snap the top thread. Especially BL since it is so strong. Good luck finding the source of the problem and let us know what worked. Hang in there! I also echo a liberal application of Sewer's Aid--both top and bobbin--to maybe ease you through this quilt.

sewlinzi Posted June 30, 2010 Report Share Posted June 30, 2010 I was using Aurifil 50 on top but it did not combine well with the cotton prewounds... Far better with same on bottom and So Fine is the best in bobbin! Link to comment Share on other sites More sharing options...

quiltiste Posted June 30, 2010 Author Report Share Posted June 30, 2010 Thanks, Linzi, yes I think I am going to steer away from using bottom line anymore. I really like Aurifil, but need to try So Fine too. Thanks again! Link to comment Share on other sites More sharing options...
