Who among us has not smiled at the sound of the springy, mid-century door stop?
Ba – WWAAAannnnngggggggg!
We liked it so much we kept slapping the thing until our parents chased us out of the house with a rabid ferret.
I have one installed on my workbench. I inaugurate significant, well, not really significant, but noteworthy events, such as driving a screw home or sharpening a knife, by slapping the thing.
But it occurred to me that if married with a sound board, in the form of a hollow box, the Ba-Wang could be amplified to BAAA-WWAAANNNGGGggggg!
And so it was. I had to hand a remnant of a former project – a book slipcase – that didn’t pass inspection.
But wait, there’s less: this sounding board/former slipcase can also resonate a tiny music cylinder.
The merest of challenges here was to form something of a crank by which the music cylinder could be turned. The tune? For He’s (she, they, it, undecided, neutral) A Jolly Good Fellow (shela, mate, team).
Drilled and tapped (10-32) a bolt connector, flattened the end of the brass rod, then sweated onto the nether end of the brass rod a speed control disc from a 90 year old wind-up-phonograph
