Dave,I'm not sure if there's any "correct" or "Incorrect" way of learning this,I'm trying to get traineeship for art castings but it's really hard to get a free place for it.
But there's definately nothing wrong about learning it in hobby version I guess,as long as it is an enjoyment for yourself.
Looking at the old masters of bell casting I can mention they had good knowledge of casting arts + experience in making constructions ,and the profiles of bells were mainly developed by "trial and error"method and ,after recieving a satisfacting sound ,further developed.
And for me it's amazing to see how many ways are possible to construct a profile for the strike note you want to hear (I know at least 15 different bell sizes that make the same note all in all &every bell got an unique sound).
Each object with a circle shape can ring ,that occurs with tubular bells or windchimes as well
@xlchainsaw : any adress for the wooden dividers?
Gonna search for a place to buy the other tools as well.
