Hi, I was given a little toy piano and I thought I would "restore" it just for my own amusement. It has 12 metal bells, which sound the major scale notes from A#5 to F7 (roughly). There is one bell (D6) whose size appears to fit in the scale, but is way flat, by almost an entire whole step. I have seen orchestral bells which are tuned by drilling a dimple in their center, so I thought I would be clever and drill a small dimple in the bell to sharpen it. Well, instead of sharpening, it went even flatter. (From about 975Hz to 950Hz, and the target is 1100). Can someone help me get my pea-brained head around the fact that removing material from a bell would LOWER its pitch, where I would have thought that removing material would make it lighter and more flexible, and therefore RAISE the pitch. Any ideas about what to do now? Drill the other 11? Or, does anybody have a spare D6 metal bell lying around? Thanks. David B.
