Depends what tools you have. Disk cutting, box joint making, swaging
of collet settings, ring sizing, flat sheet decorating, letter
punching, riveting, bending, raising, embossing, hollow half bead
making, solid bead making…
adapting any tooling that came with it would give you something
useful but knowing a decent toolmaker would serve you well. Failing
that you would need a prototype and someone to do spark eroding.
This is not too expensive as it is mostly automated and a workshop
that offers such a service will do most other jobs as well. I hope
that inspires you a little.
