The nozzle becomes very worn as operating hours accumulate. It starts to lose diaphragm tension, the pitch drops as it becomes loose, and the sound output diminishes. Eventually it will go silent, and thus totally fail. Remachining restores the factory spec dimensions and performance, as-new.
@@b2major9th Interesting, I always just thought a horn that didn't sound right must've just had a worn diaphragm or possibly an obstruction in the bell. I didn't know the metal itself could get out of spec and change like that. I hope that's a different way of saying what you said, that the metal wears and gets out of spec. Interesting.
What happens after so many hours that would require more machining?
