Below are a series of photos showing the fabrication of the wheels for the remontoire system. These are based on designs settled upon in January 2006 and based in part of Henri-Bernard Wagner's design c. 1850. Click for more information on remontoire. The large pinions shown in the fifth photo (and all other large pinions) will have their sides dished and polished.
The next four photos below show the importance of the creation of the original mockup. The fabricated parts are shown being inserted into the mockup to see how these will perform into the final concept for the movement. One will see as the project continues how the final fabricated parts will be far more refined than than those in the mockup. The final designs in metal are much more complex and refined than in the wooden mockup. See video below.
Below is a custom made injection molding die for the plastic rings and dust caps that will be used to make all of the pivots that will be equipped with modern roller bearings look to like the rest of the real jeweled bearings in the clock. Note that at this very early phase of the project, all of these calculations for the possible sizes have been taken into account. The last two photos show what a typical ring covering a roller bearing would look like, in this case within the remontoire differential drive system.
The two videos below show how the fabricated metal parts are fitted to the original wooden mockup parts to see how they will look and fit into the original concept model. One will see how refined the clock becomes as the metal parts begin to replace the less refined wood mockup parts.
