We used 24 gauge galvanized steel for the fan mount panel so that we could have top or bottom discharge just by flipping the panel. We externally mounted the blower so the motor windings would not be damaged by harmful paint and solvents. This process is extremely simple, it's literally just 3 wires 1 positive, 1 negative and 1 ground. Don't worry you won't need any prior experience or knowledge of electricity to cord the blower. These types of blowers do not come corded so you will have to get a grounded power cord and cord it yourself.
