I had an enlightening experience with a very wobbly ceiling fan - had about given up; For *months* I've fiddled with weights (big paper clips, sticky stuff, coins, magnets, lol).At about my giving-up point (since it is difficult for me to work over my head while standing on a bed), I decided ONE MORE TRY (like Gregg Allman ;-)). Took all blades off (4), washed them, got the goo and tape off, etc.WELL .. ! HERE'S THE KEY ! This gave me a chance to see the **Angle** of the blade "hangers" (soft metal that screws wooden blade to motor rotor). A couple were angled noticeably "flat" while a couple were highly angled relatively speaking!!I had hit the fan with a ladder several times over the years (with fan running), the blades have some nicks, but I NEVER THOUGHT to look at THE ANGLE ! Just think "Airplane" or "helicopter". So my theory is, or suggestion anyway, do consider the BLADE ANGLE -- as a couple people have pointed out other ways to get a sense of if the blades are all level (equal distance from the floor - I say floor because my ceiling is angled!). VERY important aerodynamically if you will, as opposed to specifically a weight issue.Food for thought ..... good luck!
