12th November 2015 / Double Pendulum Clock with Wandering Moon & Planisphere (Read More)

This has seen the culmination of several weeks planning and making, the Sidereal Conversion train is now fully in place. I have shaped and finished all 7 of the cocks, jewels and endstones have been fitted and set to height and I have shaped the lower plate to reflect the profiles of the two larger Sidereal Conversion wheels, even the screws have been given a preliminary polish and bluing.

I have re-arranged the layout and size of the cocks so the Sidereal Conversion train is now more visible and I think more pleasing to view.

Next I will be fitting the eight movement support pillars and the weight line posts to the back plate then mounting both large plates to a test board fitted to the wall. The pins need to be made and fitted to the escape wheel and the pallets made and we will be ready for a test run.


Sidereal Conversion 1 & 2; photo 1 shows setting the depth of two of the Sidereal Conversion wheels in the depthing tool. Photo 2 has four of the cocks fitted in place and shaped, the initial pencil outline for the final shape of the lower plate can be seen .
