Wobbly ceiling fan
I have a ceiling fan with a serious wobble. I've done my level best to
balance the thing -- it's better than it was, in that it no longer terrifies me to run it on high speed, but it's still not right (22g of weight on a single blade tip seems excessive). The wobble makes a noise somewhere in the mounting hardware, which is not so good with a bedroom ceiling fan. SWMBO does not approve. So, any opinions on pulling the fan down and taking it to the workbench to maybe get it balanced better? I know the runout is pretty far from OK, and that's hard to fix right while it's still dangling from the ceiling. It also seems that static balancing might be a lot easier with the fan temporarily mounted to a vertical surface. Thanks, -Scott |

Couple of questions to help sort this out: For You: Is the fan housing loose on the mounting/box to which it is attached, i.e. can you wobble the whole unit back and forth? Maybe you need to "heavy up" the mounting system above the ceiling?!?!? Everything that's supposed to be tight is tight, and the ceiling box is the right kind for a fan. There's just enough play inherent in the pipe mount that things will still move around. It's no different than other pipe mounted fans I've seen. -Scott |

Sure, I paid $130,000 for the fan, and for that kind of money I'd have expected a better piece of equipment. OTOH, the attached house and plot of land are pretty nice. :) -Scott |

I would guess, conservatively that I have installed at least 20-24 ceiling
fans in the past year or two. I have never, not even one time had to balance the blades. Now, if you are having difficulties translating that into, " I have a bad fan maybe I should return it", then you spend the next month of your pathetic life "static balancing" the one you have and then come back and tell everyone how you were able to invest 4 weeks of your time, ( which is obviously of no value to even yourself, if you're ****ing with this long enough to bother to post on line), so you could balance a ****ing $300. ceiling fan. Wonder what your wifes doing while you're playing with your fan? Hmmmmmmmmmm......... "Scott" wrote in message news:430768e3.139221324@localhost...

You start with a blade any blade and clamp the weight to that blade at the hub. Then you slowly move it outward. Look for any wobble and listen for any noise. If it is the wrong blade you will quickly notice it as you move the weight out, so move to the opposite blade. Maybe you will have to go to one of the other blades. When you get it the best you can, move to an adjacent blade with another weight. if that doesn't work then move to the the other "adjacent" blade. It sounds like you have the main out of balance figured out, but weights are need on two adjacent blades. Shouldn't take more than 10 minutes, depending on how fast it spins up. Use anything that will clip on the blade, clothes pin, small spring clamp, even a smal c clamp, or just use tape with coins. For a permanent fix, put an appropriate screw into the blade(s. OTOH, if you have lots of runout then you have poor bearings so fix those first. |

The blade tips don't ride in quite the same plane, and I believe one blade is pitched a little differently than the rest. I'm now thinking that balance weights can't compensate for that. A new set of brackets might help. Might not. Anyway, I thought it was worth a try, as it's a nicer fan than what I can afford to replace it with. -Scott |

I didn't buy or install the fan, it came with the house. Did you not read the article where I mentioned this? No, of course you didn't. All of the fans I've bought and installed have needed a little balancing. None have been as difficult as this one. Maybe I just have a lower tolerance for shoddy workmanship than you do. -Scott |
