| Question on flywheel design |

Yes, Richard and Miner, thatīs the way it is. Replacing iron with lead is not "cost effective" inertia-wise. It would be quite another thing if the original flywheel were of aluminium. Replacing aluminium (density=2.7) with even iron (7.8), brass (8.5) or bronze (8.7), let alone lead (11.3), would be a significant increase. Making even a thin(nish) rim to an ali flywheel of anything heavier is very worthwhile. And a brass/bronze rim around an aluminium wheel will (to most people) also enhance the visual aspect. Of course thatīs not true, if youīre copying an old design, with exhibition/ museum quality ambitions... :) These are bronze. 300% more inertia compared to an all aluminium flywheel of same size. :wave: |

Richard and cidrontmg, Thanks for the information. I had a gut feeling that trying to cheat on the laws of physics wasn't going to work very well. Pete |
