Ribbon spring


#1

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?

The same type of spring is used in mechanical clocks and watches and
anything which has a wind-up mechanism. It’s called a mainspring.

Do you mean the kind of spring that is flat “wire” (like bezel wire)
and coiled - used to be wound with a key? Try Clock manufacturers or
clock restorers.

You’re describing the type of ribbon torsion spring which is used to
provide continuous power. The mainspring of a watch is such a
spring. Perhaps a clock mainspring would be large enough for your
purpose. A quick google got me to these folks:

You can also get lower-powered constant-force springs from

If I am picturing correctly what you are looking for, it it is a
referred to broadly as a “Clock Spring” or more specifically a
"spiral torsion spring" Do a google search on "spiral torsion spring"
and see if that’s what you have in mind.

The steel straps from shipping items might work. I’ve seen different
widths. Really springy stuff too.
