This fusee Centre wheel and pivot had been
glued. So i have re-pivoted it properly. It had a slight wobble to say the least the glue must have given way after a few years.
The cylinder-barrel which holds the spring needs to be bushed. I will post a few more pictures as i go.
Centre wheel with its nice new pivot.
The Fusee is basically a continuously variable gear in the form of a brass cone.
As the spring inside the cylinder begins to unwind it operates the clock through the cone
working from the narrowest point to the widest, which, when the spring is at its weakest point provides the maximum amount of leverage.the first illustration of a fusee movement was in the sketches made by leonardo da Vinci in 1490.
