I had this clock in for repair, would not run, strike erratic.
Once the movement was apart it became clear that a lot of bushing would be required on the going train. One pivot on the 2nd wheel had been done before but the grooving on the pivot had not been ground/polished out. In the end I Bushed both pivots of the 2nd and 3rd wheels and the front one of the 4th wheel. After this it ran but the escapement action was not great, lifting the pivot of the escape wheel with a finger nail rectified this so I bushed that as well. I mounted the movement through a piece of wood of approximately the same thickness as the slate, it then stopped. The thickness of the front of the case is important, too thin and the back of the chapter ring touches the end of the anchor arbor when the fixing screws are tightened. I had to make new screws as the old ones had very little thread remaining.
The strike train was erratic. The relationship between the pin and warning wheels was wrong, before the pin on the warning wheel reached the locking detent the lever which enters the notch in the pin wheel was already beginning to climb out again taking the locking detent with it. I corrected the relationship between the count wheel and the pin wheel so that the lever dropped into the centre of the notch then attempted so fit the warning wheel. The overall length of the arbor on this wheel was greater than that of the other strike arbors so they came free of their holes before this one could be inserted. In the end I shortened this arbor by as little as possible, the pivots were over length anyway, so that the wheel could be fitted without disturbing other ones. The strike continued to get out of sync. Testing and monitoring with a Microset revealed that it struck nine every time that it should have made one blow for 8:30. Close examination of the count wheel showed that the notch for 8:30 was not cut as deeply as all the others. A touch with a small file fixed the fault. Pictures of the notches and locking detent here.
