Any tips on balancing them crappy wooden ceiling fans lads ! Instructions are naff and I have 3 x 3 gram weights to help but struggling to get them right ? Cheers

I agree with @Sooby2 .

Doing it with it mounted on the ceiling is going to be tricky. Take it down and hold it so the blades are running in a vertical axis and the heaviest will roll to the bottom, add weights to the others.

Alternatively, since you're unlikely to see the tops of the blades, countersink the heaviest slightly on the top surface to remove weight. Then you don't have to worry about securing the balancing weights. If it rolls quickly, countersink near the outer edge as the turning moment will be greater at the outer edge, slower, move nearer the centre. When you're done, stain the countersunk sections.
 
I've never done it, but if I really wanted to do it properly, it's how I'd go about it... it's how I've seen lots of stuff balanced in say engines, but as pointed out, it could take a while :)

Either that or take the blades and rotor off and drop in to KwikFit for a quick spin on their wheel balancer :D
 
Temp Colour the tips/ends with different colours , spin at high speed while looking horizontally at them not too close mined ! . The highest spining colour will be the lightest so stop + add wieght to this / others till they aligned horizontally while spining . Used to do this with my RC Helicopter all the time n works no probs.
 
Couple of things you could try is remove all the blades and weigh them on an accurate scale, apply compensating weight to the lightest blades but do it with small weights (pieces of blutac) applied evenly along their length. Secondly make sure all the blades are mounted the same way up, I've seen a few ceiling fans where one of the blades is mounted upside down and it's not obvious without looking closely.

That's got to be the most unusual reply I've seen on this forum :)
