How to tune a bell ? Answered
I'm building a doorbell-operated carillon of bells, which will play the "Westminster Chimes" on a set of real brass bells (the sort with a wooden handle that you would normally shake). They will be hammered either by solenoid mechanisms, or by mechanical triggers, driven from a pinned rotating drum. My question is - Is it possible to change the pitch of a bell, either by removing metal, or adding metal (with a weld), without ruining the resonance or the tone of the bell ? - And upon what part of the bell would you perform this action ?
