Are you willing to spend fifty bux? Harbor Freight has a small Hossfeld
type bender that would do the job easily. Speaking from experience, I would
just eyeball the bends, using the first one as a pattern for the others.
You can do six in less time than it would take to set up a jig, with the
trial and error to eliminate the springback error.

For a metals sculptor, having a small bender will be an asset for all future
projects.
