Help! thread shredding

[Neher-in-law5 253]

I am trying to get a panto done on a deadline quilt and the thread keeps breaking.  Have the same magna glide bobbin in with all breaks, the bobbin thread doesn't break or fray.  Seems to be a good bobbin.  I have slightly changed the tension on the bobbin and it seems good.  I started out with Magnifincgo charcoal gray thread and had two or three breaks immediately with the design.  I didn't even get through 6 inches of pattern.  Took that out and started again with Rainbows, a cone I have used before with good results.  Still getting the same fray/breaking.  I have changed needles twice, checked for burrs on the needle hole in the plate, around in the bobbin case and assembly, changed bobbin cases (no spring in either case) and used static guard. 

I have just finished a king sized DWR with no fraying/breaking problems and another king size many pieces kit quilt.  I have run a piece of pantyhose through all thread openings and holes that I can find, it was oiled/cleaned before starting.  What else can I try?  I had hoped to have this quilt done by Monday night to give to my sister to take to Japan.

 

Edited:  The fray/break always is right at the needle plate/bobbin length when I untangle it back in place.

Thanks for any advise and help.

First off, what did you change after doing the previous quilt?  I would say possibly looking at the needle hole direction.  It should be closer to 12 o'clock than 1 o'clock.  Otherwise, it seems like you have checked everything that you should have.

Maybe try some Sewer's Aid or silicone on your thread.  I find that in the winter my threads get a bit dry and the friction can cause thread issues.

Did you check all your pig tails?  Check your thread path also to make sure it's not catching the screws holding the pig tails?   Check to see if your quilt top is pulled to tight across the rollers making your needle flex a lot?

I was able to finish the quilt---King Tut to the rescue!  I flipped the pigtails (had used emery on them too) and checked the screw heads with nylon and emery.  I may have had the sandwich too tight, but  was able to do the whole quilt with King Tut without any breaks, just a funny catch when the magna bobbin was getting low.  I figure the sandwich tightness and winter humidity is probably the culprit this time. 

 

Thanks for the help.

Glad you worked it out.

Yea, glad you got it quilted.  I've never used the Magnifincgo but my Millie hates Rainbow it always shreds however it runs great on my multi-needle embroidery machines.

Whenever I have issues with thread shredding, I change the needle and go up one. For example, I might up to size 4.5 and that usually does the trick. I also use my handy Sewer's Aid which is handy dandy to have on standby.

Thanks for all the encouragement and support.  I was able to hand the quilt off to one sister to deliver to Japan in a week when we took the previous quilt down to FL to celebrate another sister (early birthday, 6 months early!) with the quilt we made for her.  I will need to post the pictures when I get on the other devices.
