I am trying to watch Wimbledon in this hot weather with a fan to cool me, but the noise and vibration from the fan is distracting. Can anybody suggest a methodical way of balancing the fan, or is the trial and error method of attaching weights to the blades at random my only option?
The fan is a 3-bladed plastic job that does not stop at any particular position when switched off so there is no obviously heavy blade. The motor runs smoothly and without vibration with the fan removed. I suspect that, like car tyres, dynamic balancing is needed rather than static balancing, but I would be glad to hear otherwise.
