RE: [CAD_CAM_EDM_DRO] Toroidal Bore, Revisited

Joe -

I think someone should talk to (shoot) the designer. It sounds
irresponsible &/or naive to design something so difficult to produce.
Almost sounds like an aerospace/medical/government project where $$ is not
an issue, and the designers often get used to not having to worry about how
the part gets made. Bill accordingly, they're used to it. On the other
hand, if the part is for yourself, forget everything I said.

Any reason the part couldn't be split into two halves? What's the part for,
anyway?

Lots of luck,
Carlos
