![]() ![]() The weight specs list it as 4.7 or 6.6, however this is really being too picky. Also this rule is not for all Grandfather clock weights but the vast majority of the post WW2 German units. These specifications do not apply if the clock has 5 or 9 big tubes on the back. This changes to and in 60mm diameter if the pendulum bob is 8 1/2 inches or wider. A movement that is rectangle in either chain or cable will use and LBS in 60mm diameter. If the pendulum bob is 8 1/2 inches or more, change that rule to lbs and in 47mm or 43mm. These are available in either 47mm or 43mm diameters. If the movement is square and chain driven, it will require lbs and lbs. If the movement was made in Germany, post WW2, we can safely make the following assumptions. There is also another way to go about this task, which may be easier. Once the manufacturer is known and the starting numbers of the movement, use the chart to see the weight specifications for the Grandfather clock weights. Use the movement identification page to find out who made it. The stamp with these numbers are right on the back plate. The numbers on the movement is what will lead to getting the correct manufacturer of the movement not the names on the movement. This can be deceiving because the movement can have any name on it, but it may not be the true maker.įor example, a Hermle unit may have the name Sligh, Ridgeway, Howard Miller and so on. The weight chartīefore using the chart, you need to know who made the clock movement. The bob is the round disk at the bottom of the pendulum. The diameter of the bob in another piece of information that needs to be known. Once the movement number is known, cross reference that with the weight chart. This information will not be on any of the paperwork or clock case. This requires getting the information off of the back plate of the brass movement itself. ![]() If needing a complete clock weight, we need to determine what the appropriate weight is for the clock. Any part of the weight is available on its own. The Grandfather Clock Weights Description on this web page will cover what is meant by weights and their parts. ![]()
