Needle taking bites out of bobbin

Recommended Posts

I just bought a used long-arm that I believe is a Millennium with an Ultimate II.  I was quilting right along today when I started to hear kind of a thunking noise and then I broke 2 needles.  When I took my bobbin out I noticed grooves on the edges of the metal bobbins,  Has anybody experienced this problem?  Any advice would be appreciated.

 

Thanks,

Hi Jonna:

Make sure your needle is in correctly: it has a curve and the curve should push out towards you so the scarf can pass behind the needle, and make sure your needle is pushed up as far as it will go before tightening it.

Did you get the owner's manual? Take a look in there for correct needle placement.

Maybe someone else will chime in here, or Dawn when she is able to, otherwise call APQS when they are open as you will get great support.

Hope this helps,

One of my customers had a similar problem: turns out she had removed the backlash spring inside the bobbin case, allowing the bobbin to work its way closer to the needle. Is your spring still in and keeping your bobbin out of harm's way?

Jonna:  It sounds like you might have end play in your hook shaft.  Pull and push on the hook.  If it moves any at all, the end play needs to be adjusted.  If the hook moves back and forth, sometimes it will stitch OK, and other times the hook could hit the needle.

 

BTW, I'm intrigued by your description of your machine.  Tell us more.  Good luck.  Jim

I hope you have a manual that  you can refer to.  If not, APQS may be able to send/email one to you.  You will not know what the name of the parts are or how to do any corrections without it.  Call APQS, they will help you on this and guide you along to correct any problems.  Don't use your machine again until this is resolved as it could cause more issues.
