So I need to make a bell out of brass that rings at 921 hz. I was thinking of turning a bell shape on a lathe and then spinning a piece of brass over the form. But I have no idea what size to make the form in order to get close to 921 hertz. I do have experience access to a calibrated mic in order to tune the bell. Any suggestions on how to proceed
Must it be a bell?
A lot of variables go into the bells resonant frequency.
A chime or a fork is a lot easier to tune, a chime is as simple as cutting pipe to length and taking a few measurements at a few lengths to work out the formula, which can get you very close and you just grind down the last bit to tune it exactly.
It must be a bell. Bells are beautiful and it's a gift.

set up an arduino to play 921hz tone inside the bell when the hammer makes contact with the sides.
Am I gonna be the one who asks?
Why 921?
921 is my anniversary and the gf likes sappy shit. INB4 feg. I'm an engineering student with lots of hands on knowledge. Prolly gunna just spin one on a lathe and see where it lands me.
