Balancng a paddle fan.

How do you "balance" a paddle fan that "wobbles"? As best I know , this type of fan may need a "balancing kit' which is sometime included in the package.

Can anyone answer WHY it "wobbles" when it's "factory engineered"?

Thanks!!

Quality control, I suppose. You get one or more blades that weigh a little more or less than the others and it unbalances things. You can get kits from the big box places. I recently had to balance one of our daughter's.

Factory engineered and produced by the hundreds of thousands in Asia.

I don't have much faith in the balancing kits. I've used them but it takes a lot of patience.
Many times I'll swap two adjacent blades and the problem is reduced or gone.

I've also cured a couple by buying a package of replacement blades and simply replacing the set.

There are methods to balance a fan. Almost all fans need to be balanced. Part of the problem is installation and part is material quality control. Start by using clothes pins at the tips. Start at low speed. If you can use a stick of chalk and a steady hand to see where the wobble is. Compensate in the opposite side. When balanced at low speed go to high speed. re-adjust clothe pins. Note: placing pins at the end or along the length of the leading and/or trailing edge will make a difference. It will take a lot of trial and error. Go back to low speed and adjust again. Then try the mid range speed. Once you get it balanced to a near non wobble place pieces of clay of the same weight (use a postage mailing scale) at the same spots as the pins. A little bit of wobble is OK.
