Perfect for making low cost grandfather size clocks, but if you use your imagination, it will does much more. These are the Large Clock Pendulum Drive Clock Instructions.

  1. When opening the device, please note that there is a separate battery well with wires and a connector. These need to connect to the pendulum drive. In most cases it is best to mount the battery well above the pendulum drive.
  2. This large clock pendulum drive has a very unique feature. The part of the device that powers the pendulum actually has a “hinge”. Meaning, with proper installation, your clock can be a few degrees off level and still work properly. If you cut a 2” wide by 5 5/16” long hole in the board you are mounting this to, (this is the measurement of the rectangle when looking at the back of the device), this will allow the hinge in the pendulum drive to move back and forth if need be.
  3. The installation of both the battery well and the heavy duty pendulum drive require screws. We do not supply the screws because the type of screw you use needs to be specific to the material you are mounting this device to. You will need 6 screws.
  4. Mounting tips: Please consider how far behind the dial of your clock you want the pendulum to swing. You will need to attach the heavy duty pendulum drive to a board of some type that is hidden behind the dial of your clock. Please make sure that this board is in a place that the device can easily be made level.
  5. Swing adjustment: This device operates by an electro magnet that is sits between two magnets that are on the pendulum arm. If the swing of your pendulum is too wide, then you can put a piece of tape over one, or both, of the magnets to reduce the width of the swing of the pendulum.
