Q. I have never been able to sew with metallic thread. When my customers come into my store with the same problem with the thread, I can't help them.I have tried all of your suggestions plus the suggestions by Dawn Cavanaug for APQS Quilting Machines. I can get nothing to work in other brands, or yours.I am using Bottom Line in the bobbin.I have loosened the top thread as much as I can. I use a new needle. I have tried both a top stitch and a metallic needle in a 14 or larger. Today I even tried loosening the bobbin tension. The thread still keeps shreading and breaking. I have a Brother 4000 D. It works fine with all of your other threads, but not the metallic.
A. It sounds like you are doing most of these already. Here are some ideas:
1. Needle: Topstitch or Metallic #90/14
2. Top tension: loosen to a "1"
3. If a spool, position the spool on the vertical pin holder or is such a way that the thread unwinds directly from the side of the spool with the spool rotating
4. If a cone, thread must unwind straight up over the top of the cone
5. Bottom thread: any smooth polyester. The Bottom Line is best.
