I have also looked, didn't find much - did find some whistling yo yos. :D So probabily needs to be hollow - with some holes in it. Seemed a good idea at first, - now I'm not so sure. :doh: Surely someone must have some thoughts. :smart: DaveH |

Still thinking....... if it is a solid flywheel just drilling radial holes might be enough but I fear it might be impractical in a small model as to get pleasing audio frequencies it may be necessary for the flywheel to be a foot or so in diameter. :scratch: |

John, 10000rpm I was thinking in the range 50 - 100rmp. What about holes drilled radially on the periphery of the flywheel towards the hub, with a small holes near the hub. Well I know what I mean :D DaveH |

I can make a hollow fly wheel that's not too difficult - where to drill and what size and number of holes seems tricky :doh: DaveH |
