![]() ![]() German units measure the pendulum from the top of the movement to the bottom of the nut threads. The length of the pendulum on German units comes in a few CM options. Grandfather clock pendulum information begins with the obvious discussion of length. Moreover, no mechanical pendulum clock will run right without " Putting The Clock In Beat" first. This is very easy to do and only takes a few minutes. Pendulum clocks need to be put "In Beat"įinally, after installing the new clock pendulum the clock will need an adjustment for it to run correctly. Likewise, a smaller diameter bob can be used, but not a larger one. That measurement is the largest diameter Bob that can be used in the clock case. Measure how wide the inside of the clock case is and then subtract 4 inches from that measurement. bob width is determined by the inside of the case width. Of course, bob diameters vary so that they will not hit the sides of the case. Determine Bob Diameter after Pendulum Measuring on German Clocks The pendulum may be shorter, although it will be correct. ![]() Ordering a pendulum for a Hermle 94cm movement, does not mean a 94cm long pendulum will arrive. Clockworks will calculate the length, making sure it is correct, before shipping it.Ī customer may receive the pendulum and think that it is not the correct length. Naturally, if the clock says something like 94cm, choose 94cm from the list, making sure it also lists the correct bob diameter. Measure the pendulum on a German Clock from the very top of the movement down to the very bottom of the pendulum rating nut threads. Once received, the pendulum install it on the clock, then Put The Clock In Beat. They all come with a brass round bob for the end, but leading down to the bob can be any of these three styles. ![]() Decide between Lyre, Wood stick, or a brass rod pendulum if the options are there. This will be the maximum pendulum bob diameter that the clock case can handle. Measure how wide the inside of the case is and then subtract 4 inches. Match these numbers with what we are offering. Get the CM numbers, or PL numbers from the back plate of the movement itself. Then return to this page to continue the process of pendulum measuring on German Clocks. They made movements for other clock makers who had their own name on the movement because they were buying so many.īest to use the identification page to narrow down exactly who made the clock movement. If none of these names are on the movement it is still, most likely made by one of these factories. If the clock was made in Germany post WW2, it will be one of four makers. First, know who really made the movement. ![]()
