Large Heavy Duty Pendulum Drive Mechanism

New and Improved! This heavy duty pendulum drive mechanism will run up to a grandfather size lyre pendulum! Saves money – allows the use of an inexpensive battery movement to run the time, freeing you from the use of expensive mechanical movements. Because the mechanism is top driven you can design clocks where the pendulum is in the open. Great for large or small wall or floor clocks. Mounts inside case. Pre-drilled mounting holes.

**When choosing the proper batteries for your clock, please consider the following information: There are many brands of alkaline batteries available on the market today, but there are several brands out there that just don’t perform well in clocks. We recommend using Rayovac or Duracell brand. Other brands, such as Energizer, have extra plastic coating on the negative end of the battery, which can cause clocks to malfunction or not work properly at all. Alkaline batteries are the only type of battery that should be used in clocks. Lithium powered or re-chargeable batteries will cause your clock to malfunction, or not function at all. Lithium and rechargeable batteries are meant for “high-drain” devices, such as digital cameras, etc. Alkaline batteries are best used in “low-drain” devices, which includes clock movements.
