Using an 3/0 blade in my jeweler's saw I cut both bow-tie shaped pieces out. While I could have used shears I don't care for the distortion I get when using them for pieces like this. I feel the time extra time required to saw them out is more than made up for working with distortion free pieces.

The next step is to square up the ends of the smaller inner band blank in preparation for soldering. They must meet squarely with no gaps. The sides just need to be close at this point. They will be cleaned up in a later step.

The band is then bent into a rough circle with the ends meeting square and tight. Solder with hard solder.
