Combined stabiliser and beat adjuster for Vienna regulator
Upon completing the Vienna regulator shown in the first picture (mouse over pictures to see file name), I found that the case swung to the side when the door was opened, due to the weight of the glass in the door. The solution I arrived at might be of interest to anyone with a similar problem. The second picture shows the lower rear side of the clock case, and the cavity between the base of the case and the base of the decorative lower mouldings. In this space, I fitted a block with a vertical groove (protected against wear by two recessed aluminium plates). The block can slide from side to side on an upper and lower rail. The third picture is a close-up of the block, the fourth picture shows the block pushed over to one side. The groove in the block accepts the head of a screw in the wall, filed to size (fifth picture). This stabilising screw is vertically below the main screw near the top of the clock that supports the weight of the clock. The sliding block can be locked into position with a brass cup head set screw located at the very bottom of the clock case and at the rear of the case.
So the procedure in setting up the clock is to roughly centre the sliding block and lock it in place, hook the case onto the main screw on the wall at the top of the case, and move the case side to side at the bottom until the lower stabilising screw drops into the groove in the sliding block. Put the clock, weights and pendulum into the case, and adjust the beat (get an even tick tock) as well as possible using the slipping clutch mechanism in the pendulum leader and escapement. Then loosen the locking set screw at the base of the clock, and move the bottom of the case very small amounts left or right, to get the clock perfectly in beat. Then lock the set screw again, thus enabling the groove and lower stabilising screw in the wall to prevent the bottom of the clock case moving when the door is opened.
I've had the clock on and off the wall a few times in the last couple of weeks and the system seems to work very well.
Hope the description makes sense.
