I've been having this problem. It's intermittent, and it's been driving me nuts. The shredding bunches up above the eye of the needle. My problems started after I installed the aftermarket needleplate that has markings, and cranked my stitch length to 9. (Juki needs to provide marked needleplates--there's a market.) There is something called sanding cord. Amazon sells it. My hubby might have other suggestions; he's in the steel industry.
This is happening with my DNU 1181n and I'm scared to start dismantling the hook,etc. Did you have any luck? Mine seems to be the worst as I'm working on layers with a welt cord. Perhaps its pushing the needle and the hook is rubbing? UGH!
Hi I'm using Kingstar walking foot and the top tread is looping underneath even thoug tension knop is fully tightened and the bobin case is not too tightened.
So I checked and the hook on my machine does nudge the needle right where the thread is and I get a gathering up above. How do I move the bobbin casing back so it doesn’t hit the needle or do I move the needle casing
Great video Steve! One other thing that can cause shredding is if the needle is not in straight. So glad to see you are back at the shop!! Hope Jose is doing well too!!
I just got a Brother DB2 B714-3 and the problem I have just worked out, from watching this video, I had put my needle in backwards . Thanks for the video showing the bobbin case missing the needle. Mine was hitting at every turn and I was sure it must have been bent having put it in and out many times. Best to look for the simple things first. Cheers from Australia.
Thank you for showing the trouble spots. I have been having shredding with high quality threads on my juki tl98q. I can see that the needle almost touches the side of the hole in the needle plate. This was a used machine that has worked beautifully until I began quilting a very heavy quilt sandwich. I felt myself pulling the quilt to move in circles (free motion quilting). I hope I can fix this and didn’t pull the whole needle assembly off center. Again thanks. Very enlightening.
Informative video Steve, the part you were sanding on ( rotary hook)with emery cloth is called the thread guide deflector plate and it’s purpose is to guide the top needle thread around the bobbin case thread supply and also acts as a “cast off” ( like the take up lever) pulling off just the right amount of thread from the bobbin through the bobbin case tension plate for the next stitch. We always recommend that the 4 screws holding the deflector plate be removed and polish plate with a rubber abrasive polishing wheel DR425 ( Dremel) then hand polished with 3M Crocus Cloth and then Reinstall deflector plate. This way there is No Way to get grit from sanding in the rotary hook raceway which would cause damage and premature wear in raceway!
Great information. I have had my machine for less than a year and last night the bobbin got jammed. Today it took a few hours but I finally got it out and luckily I had a spare bobbin case. The thread was shedding slightly prior to that so I don't know if that was the problem but any help in preventing this from happening again would be appreciated. I have a juki du1181n. Thanks
Things I try when this is happening, start sewing and watch your thread coming off of the spool… make sure no snags on path down Change your Bobbin thread it might have a burr or be close to the end Rethread the whole machine Change your needle Change your fabric and thread for a test Try sewing a test piece of paper or fabric just to see if it’s working on some thing else
Great video found some burs on the plate and sanded/polished to a mirror finish. Anyone know if the Juki 241H has the flat spot on the hook shaft like the 1541s?

Thank you for all the videos you upload. They're incredibly helpful and many of the issues you address are not covered in other videos online.
No problem.
Hello Steve, how do you move the hook from the shaft cause that is what is breaking my thread?
So I checked and the hook on my machine does nudge the needle right where the thread is and I get a gathering up above. How do I move the bobbin casing back so it doesn’t hit the needle or do I move the needle casing
mitchell abrasive cord for smoothing holes. next video clean parts with tooth brush before

Excellent tip! Jose is doing well. Thank you Kathy.
Thank you for great information! Would you please post the chart for the size of thread and the needles?
Thank you 🙏
Thank u for another great tutorial 👍
Mine ALWAYS shreds 18 needle with 69 bonded nylon. 😡
Mine too with my 1181n....did you find resolution?

Yep. Same. I feel dumb. Haha😅😅

Thank you Steve some excellent points to look out for there I'll remember to check them if I have such a thread problem
Emery cloth sand paper,
Thank you very much, this is a very helpful video!
Informative video Steve, the part you were sanding on ( rotary hook)with emery cloth is
called the thread guide deflector plate
and it’s purpose is to guide the top needle thread around the bobbin case

Did you resolve this issue? I'm currently in thread shred hell in the middle of a client project same model as yours.
I hate to admit this, but after watching your video, i realized that i had the needle turned backwards. Easy fix. Consew 206rb-2
Need a video on timing industrial zig zag please machine is similar to Do consew or tacsew 146
It seems to me that the bar that holds the little hook on my machine doesn’t engage with that hook enough. Can the bar be bent (damaged) ?
why it happens? when I sew long backstitch the thread shuredding.
Things I try when this is happening,
start sewing and watch your thread coming off of the spool… make sure no snags on path down
Change your Bobbin thread it might have a burr or be close to the end
Rethread the whole machine
Change your needle
Change your fabric and thread for a test

Good tips. Thank you.

I don't think it does. The 241H did not have a safety clutch from my recollection, so no flat spot.
Thanks for the videos and great info
Hi. Very informative videos. Thank you for sharing.
Glad it was helpful!
Happens to me ALOT.
👍👍👍
I thought thread was bigger the smaller the number.
Not the Tex size. These go from small to large. T45, T70, T90, T135, T210 and so on.
Yep
Thanks Steve - super helpful!! You are a great teacher and editor. Rod - have subscribed.
