Thank you for your help, but I guess my request was not clear. The coils are already made the way dvd suggests (GMTA).
The question is really how to cut the coil, and as an extension, flatten the ring in the process. Right now I am doing that part manually.
I have a low volume application for making machine cut rings. The wire is 14 gauge. These rings should finished closed, with a minimal closing gap. The ring is 3/8" ID.
My question is: given a small coil of wire that is wound to the proper ID, how do I make a die to produce further...
