Good quality French Clock Pendulum (2) 38mm Brass Bob and Hook with 260mm Steel Rod
Dimensions (Approx) (2) 38mm bob diameter = bob width: 11.1mm / 80g Rod = 2.5mm thick. Threaded section = 30mm long Information on fitting and repairing pendulums here: https://www.m-p.co.uk/muk/ryoc/ryoc-page28.html Why doesn't the hook supplied fit the rod? A new French hook is designed to fit any rod, not just new ones, so the hook and its hole has to be small. A new rod is designed to fit most common bobs, so has to be larger than some original rods. To make them fit each other, enlarge the hole in the hook as much as possible without weakening it. Reduce the diameter of the rod where it goes into the hook with a flat file. Some repairers thread both items to make a quality fit. Others make the items a friction fit and either silver solder them apply a little adhesive. We cannot reduce the diameter of the rod for you because you will have to cut it to length first. Pendulums Pendulums are available for most types of clocks and the correct length is often stamped on the back-plate of mass produced clocks. American clocks are in inches, German in mm, and French in lignes.
For French clocks, you may find a number such as 4.2 on the backplate. Multiply the first number (the 4) by 27.02. Multiply the second number (the 2) by 2.256. Add them together and you will have the pendulum length in millimetres. French clocks usually have the movement serial number stamped on the pendulum. If there is any discrepancy in this and the number on the backplate, and the clock cannot be regulated, it may not be the correct pendulum. VIEW OUR SHOP HERE | |||||||||||||
