How do I make the mechanical clock strike the hour?
- If the new movement is not striking the hour. Since the dial is off the clock still at this point you can see the saw tooth rack, the big thing on the front of the movement that looks like a saw. This is supposed to be in the up position as it drops down on the hour hand tube snail when its ready to strike. If it falls behind the snail instead of on top of it, when you installed the minute hand it can squash it behind the snail instead and mess things up. If all that did not make sense, well just take the minute hand off and run it for an hour and then reinstall the hand. It will be fine.
Now at this point you have the clock running, chiming, and striking. The dial is still off but the hands are on the clock. The hands point to the right time when the clock chimes and strikes. Now its time to let the clock run for 1/2 a day or a day with no dial on it to be sure all is well. If there is something to be done with it, no sense in having the dial in the way. Also it will let you see what is going on if there is any issue at this point with no dial. One other reason is if the clock is doing well before the installation of the dial, then it stops after we put the dial on, we know the issue is the installation of the moon gear / dial and not the movement itself. If it has given no issues for a while and we are confident in its performance now we can move on to installing the rest.
