When I moved the fan blades were taken off my twin fan with light in the middle Harbor Breeze Model LGF dated August 2006, the fan was put back together without the blades attached, I no longer have access to the person who removed the blades, how do I put the blades back on the fan motors. This is not a normal insulation the blades are inserted into slots attached to the motors.

You likely have to remove the light kit, and you will find a place to put the screws through, you will have to rotate each blade to that opening to install screws.
If this is the type I am thinking of.

Not sure of your particular model but some of the newer fans have twist and lock blades while others have a push and lock. Do you have screws?
