I am currently trying to make a clock out of a teaching clock, so that it actually tells the time.



I tried a so called high torque quartz movement but it was just not up to the job. So I though perhaps a mains unit would have more power.

Trouble is you just can't buy them anymore, apart from turret clock movements at a very high price.

Any ideas?

I suppose a teaching clock is one with no works but movable hands ? What's the diameter Don...

It's about 30 cm diameter. There is a lot of unavoidable friction inherent in the design.

The movements from Cousins were the ones I was considering. May have to go that route.

I have a big Gents' slave movement, which would work, but I have no master clock at school.

Thanks.

How forgetful one gets as one gets older. Looking for something else entirely I found I had an old Smiths synchronous movement that I had ripped from a Gents' slave to retrofit a slave unit.
