ABSTRACT:
A method of balancing a movable rotating object having multiple radial projections, such as a ceiling fan, the method comprising the steps of: attaching to a non-rotating portion of the object a source that emits a focused light, directing the focused light at a target, and then attaching a weight to a location on one of the rotating projections. Then observing the orbit traced by the light source on the target, changing the location of the weight to another location on one of the radial projections, and then observing the change in the orbit on the target.
