These have been made by watchmakers using hand held gravers for more years than I care to think about. Many driven by a bow.

Clock makers usually use engraving brass, not suitable if you have to bend it


24/10/2019 16:36:04


If you you need to bend it, engraving brass is not suitable, it will crack

Thread: Oiling an old clock

Clock oil to lubricate. Really should be dismantled to be cleaned properly. Could try washing the pivots with lighter fuel applied with a small paint brush ( But not really recommended )


Thread: Metal expansion
05/10/2019 20:48:01


It is a straight rod and contracts in warm weather and expands in winter ie the clock gains in summer and loses in winter . The pendulum bob is mild steel and is supported dead centre. As I said before I was told that it should have had heat treatment before I used it, and I believe that this would have been two days in a butchers fridge then left at room temperature for two days then repeated. This was from an RHS member who contacted me after I contacted them for advice

old mart

my pendulum rod doesn't, see post above


04/10/2019 13:15:50


I have an invar pendulum rod that expands with cold and contracts with warming up


ps I have been told that it should have been heat treated before I used it
