gonediving Posted May 22, 2013 Report Share Posted May 22, 2013 Can someone help me with a problem? My bobbin thread keeps breaking and it's getting more and more frequent as I am trying to finish this quilt. I started out with one break per row of panto, now up to a break every 2 minutes of stitching. I have loosened both top and bottom tenisions, changed my bobbin case, changed my needle, slowed WAY down but nothing is helping. I am using Magna glide bobbin from Fil Tek (which I have used before without any problem). I cannot feel any burrs. Thanks in advance for any advice you can give me.

witha'K'quilting Posted May 22, 2013 Report Share Posted May 22, 2013 run a pin under the finger of the bobbin case and check for lint. also, blow out the bobbin area. they is probably thread caught somewhere causing the break. Link to comment Share on other sites More sharing options...
gonediving Posted May 22, 2013 Author Report Share Posted May 22, 2013 Thanks for responding. I'm quite sure the bobbin area is lint free (I do the pin thing frequently). I clean the area with a brush and compressed air after each row. I will check more closely for a thread that could be stuck somewhere in there.

Darlene Epp Posted May 22, 2013 Report Share Posted May 22, 2013 Have you broken a needle recently? It sounds like there's a burr somewhere. Link to comment Share on other sites More sharing options...
chickenscratch Posted May 23, 2013 Report Share Posted May 23, 2013 Is it a prewound bobbin? I have gotten a bad batch of those. The emptier they get, the more the thread breaks. I have had to throw away about 1/4 of the remaining bobbin three times this week because it broke as it got empty, but a full one runs just fine.

gonediving Posted May 23, 2013 Author Report Share Posted May 23, 2013 No broken needles -can't feel any burrs. I saw a previous post of a gal with the same problem. I re did the WD40 and oiling process. Really used a lot of WD40 and actually made it through the remainder of the row without a break. Will stop for the night while I'm ahead. Yes they are pre wounds. I'm thinking that may have something to do with my problem. I've been around the block more than a couple of times and know sometimes Jupiter and Mars are not aligned just right. Thanks for all your input. You all are a great resource. Hopefully I'll get this done tomorrow and the next job will be no problem. Link to comment Share on other sites More sharing options...
RitaR Posted May 23, 2013 Report Share Posted May 23, 2013 use Sewers Aid to lube your thread, and I use it on the thread guides, not the tension disk. Now and then I use spray silicone on top, which helps the breaking.. Turn the flywheel to see if there's a thread in it. We missed one and had miserable stitching and broken threads until we learned to turn the fly wheel . I also use the Sewers Aid on the bobbins, prewound or not.. that might help. Several here, and a lot of pro's use mineral oil to dunk their cones or spool in, they dry it off by wrapping an old hand towel, etc and squeeze the extra out. It can also be left sitting on a rag to let any excess out. while you do a small job or two. It could be a bad batch of needles, too. Good luck Link to comment Share on other sites More sharing options...
gonediving Posted May 23, 2013 Author Report Share Posted May 23, 2013 Thanks for the advice Rita. What kind of spray silicone do you use and where do you apply it? On the fabric itself? I've read others use it, I only use sewers aid on the guides and sometimes on the cones. Since I don't use metallics, it usually doesn't solve a problem for me. I'll check the flywheel too - and change the needle again Link to comment Share on other sites More sharing options...
gonediving Posted May 24, 2013 Author Report Share Posted May 24, 2013 Got the answer to my problem. Just want to share with anyone who doesn't know that the magna glide bobbins from Fil Tek have a magnet in them to prevent backlash. You are supposed to remove the spring check? From the bobbin case before using them. ( the blue finger thing inside). It is written on the box if you buy a half gross. I bought the jar of 20. Not written on that....Amy Stuart enlightened me. No wonder my bobbin thread kept breaking! Link to comment Share on other sites More sharing options...
o2b Quilting Posted May 24, 2013 Report Share Posted May 24, 2013 OK...you said you use a pin under the bobbin case finger... Now try a different bobbin case. Using a pin under the finger can scratch or gouge the metal which could cause your thread to break. I always use the corner of a business card when cleaning out under the finger of the bobbin case. I collect business cards from places I don't ever care to contact but they come in handy in my studio You may also want to try popping out the tension spring in the bobbin case and clean behind it (if you haven't already). Also check and see if there is any thread wound around the post the bobbin case snaps on to...it is not always easy to see but if thread is wrapped there it can prevent the bobbin case for seating itself all the way onto the post. Good luck! Link to comment Share on other sites More sharing options...
