After struggling for several days with thread shredding, I noticed that the needle plate on my machine had a nick in one side. I filed down the nick and while replacing the needle plate I noticed that the needle is positioned very close to the right side of the needle plate rather than being centered. I believe the position of the needle may very well be causing thread to shred. I also noticed a very slight tink when the needle goes down as tho it is hitting the bobbin. Am I correct in assuming that the position of the needle is the causing thread to shred?
