Here are some aluminum rods cut and drilled to make chimes. It turns out that the hardness of the aluminum affects the chime tone and its ability to ring greatly. First I tried some precision ground 7 series aluminum, but that cost over $35 a rod! Way too much, I thought, so I ordered some 6 series, and they are almost - not quite - as good. These are tuned to just over 10K.
Why are we making chimes? Stay tuned for the answer.
