here is what i been workin on for a total of 5 school days
this is my homemade plywood box fan.
this fan i made has galvanized tin blades bolted to a piece of wood press fit onto the motor shaft and has 2 set screws holding it on. the motor is a 1.5 hp motor that spins at 3,450 RPM. the motor is a little too powerful for this setup, but it works. it scares the crap out of me too... FYI, that is me in the pic standing in my shop class
