Eureka clock

[John HaineParticipant @johnhaine32865]

Has anyone built a Eureka clock please, and if so what was their experience?  What materials were used for the balance assembly?

[Peter Cook 6Participant @petercook6]

I have a couple of originals which are interesting to work on.

There are a couple of people on the Electric-clocks forum on Groupsio who have done so, and there is some information  on there.

One interesting post from Neville Mitchie

discusses the central armature, which needs high magnetic permeability.

Hope this helps.

Sorry about the URL I haven’t figured out how to put a tidy one in!

Thanks Peter, I’ll have a hunt there.

Not sure what shape it is, but could old transformer laminations be a source of material, similar requirements, high permeability and low residual magnetism
