I saw propeller desing from instructable and I made it using those steps as a hobby

I've seen another video from youtube in which propeller is used as a cieling fan blade so I decided to make the same with my own desing and Ideas . I used only scrap materials which I got from workshop for free of cost (Except motor and speed controller).

You can get enough details about propeller design under this blog:

Thanks to "Michael Duffy"

Step 1: Materials Required

Wooden Propeller

motors

Chain drive

Bolt nuts

Paints and primer

Speed controller

15 CM Piston

GI tube to hold the entire assembly

old connecting rod to hold the motor and axis

Bearings

Step 2: Motors :

I used A/c outdoor unit's motor as a prime mover I used two to maintain the C.G on the Axis of the fan.

Step 3: Driving Mechanism

100 cc bike's timing chain and spurs are used to drive the propeller it's simple chain drive mechanism and used for reduce the speed

Step 4: Speed Controll

I want 100 to 150 RPM but the motor's No load speed is almost 1000 RPM also electronic speed controller(It's hidden on the piston) is used to reduce the speed as well as match both motor's no load speed
