How can you "drive" a wind clock?

Or you could go to Anchor Supplies in Nottingham by the Trent Bridge ground and buy a pair of the real things. They had boxes of them when I was last there :clap:

You got it John
We used them on the base exchange units at the iron works to tel the operators when to add charge
Google the name selsyn
They did not have a armature but a two pole electro magnet fed by slip rings , with dc both units the stators were wound for three phase these were conected to each unit but with no other conection or power the only power was to the rotors of each unit
But with some tricky wiring the sender unit could be powered as was the case in our application the weight was wound up prior to a charge dump else you would bury the weight
Good units but I would bet they are expensive
As mentioned rc servos could be repurposed

There were a lot of them around in things like radar sets, all manner of military stuff and anywhere in industry where they needed a remote indicator of the angular position of a shaft. Ham radio chaps used to buy them to remotely indicate the position of movable beam antennas etc. They were also used in wind direction indicators which is where mine came from!
The challenge with a wind direction indicator is finding something that can go full 360 degrees and more.

They've got a place about 5 mins drive from me at Ripley.
Last time I went there some 4 years ago - ish, there was not much in there compared with ages past.
Although looking now at their stock, this was of interest ...

Something for you to fly over your place ??? Impress the neighbours etc. ??

You'll need that Standard when the Queen comes to stay :lol:
I have fond memories of the Ripley yard - bought some very useful stuff there over the years When I used to travel the country a fair bit, I'd divert over the Pennines from head office in Manchester, come down the M1 and pick up Ripley, then through Nottingham to Trent Bridge, then out the bottom of Nottingham by the Ratcliffe coal fired power station.
