Ships clocks update

Here a few pics + a vid of the ships clocks. Both movements were identical Smiths but I could only get one of the platforms to run successfully (so far). However the customer only wanted one returned which had the readable dial. 

Both clocks I found with the same fault with the mainsprings that had been wound so tight they had ripped the end holes. Although I could have repaired the springs I purchased a new spring. A very simple movement with platform escapements so a straight forward repair/ service.

However worth noting I cleaned the platforms by running them through my watch cleaning machine first and then stripped the platforms removed the jewels and soaked in a degreaser. Despite this under inspection with my microscope there were still significant and stubborn deposits of dried oil on the jewels so further rubbing with pegwood was required.. The runner had to be set on almost max gain to achieve good time. I did notice this how it had been set before so perhaps the h/s is a touch short. 77F96A63-5DB8-4BDE-8EE1-452A670873A7.thumb.jpeg.0fb4a70770225b03e098b0920e5ea9c0.jpeg

Cleaning the cases one completed. Used Priory concentrated cleaner followed by liquid brass.

Not bad little movements. What is wrong with the other platform?

I really don’t know at present. Under a microscope I can not see any obvious faults.  The meshing between the escape teeth and the escape wheel pinion seems tight or even binding and it was the platform that showed no life before stripping..  I will have to have a play..After cleaning and lubrication this platform run really well and free with just puff of air so the area I suspect I will investigate first.
