This is cheaper than a new fan and you don't have to test different weights. |
|
|
The reason why fans are allowed to wobble, is to stop the force being transmitted to the base: working it loose; or creating vibration in the ceiling. |
|
|
I suggest that if you implement your clamp, the next idea will be some kind of method to stop falling fans, or to remove annoying movement of your ceiling. |
|

[phlish] is right: most fans are supplied with moveable weights. But Blu-tack works just as well. Just make sure the blades are aligned as well as you can, first. |

A heat pump would be nice too [bigsleep]. |

I'll vote for this one. I don't agree with Ling that your clamp would cause the fan to fall -- or move your ceiling at all. I think that all you would need to do is build a shimmy damper similar to what's on the nose wheel of small aircraft. It's just a shock absorbing rod. |

In theory, you should be able to stabilize a wobbly fan by fixing it firmly to a fan having an equally opposing wobble. I propose a web site that serves as a wobbly fan clearinghouse. You measure your fan's parameters (unsprung weight, wobble period, rpm, etc.) & then enter the parameters plus your contact info into the web site database. Fanware searches the database for a matching anti-wobbly fan and sends contact information to you and the other fan's owner so you can negotiate a mating of the fans, as it were. |

Another idea: a device that attaches to the wobbly fan and uses the motion there to churn up fresh farm butter! You just pour in the cream & salt! etc. etc. |
