There is another kind of spring that I am looking for and I would
describe it as a “ribbon” spring, which I would use for a centrifuge
type of mechanism - not for casting of course. This is the type of
spring seen in antique toys sometimes. I’ve googled but not found
anything, and I even considered buying a toy and removing the
spring, but they’re all very small, and what I need is bigger.
I’m sure there’s something out there that is ready made. Any
suggestions at all?
