    Does anyone know how the steel pinion gears are "attached" to the shafts on Howard #2 tower clocks? I have not had to remove them from the clock I am restoring, but would like to know how they are attached. At lease one, on the strike side is threaded on, but I'm not sure about the others.

    all of the Howards I've seen have the pinions pressed on with a key, which is actually a pin in a small pocket in the arbor. Only on the strike side, the rack hook, is a nut used as a retainer. The gathering pallet as can readily be seen uses a taper pin. It is not uncommon to find it very hard to press off a pinion gear. Depending on what you use, you may bend the pivot. Personally, I've never had to press off steel pinions, but Ive done a few that were brass.
