How To Make A Propeller

A propeller is a type of fan which fuels power by converting a spiral spinning motion into thrust, used for propelling an aircraft or a boat in a desired direction when spinning; and here we are going to talk about how to make a propeller. A propeller basically the center hub and spinning blades placed in a manner so that the blades spin in a spiral. This spinning technique is often used to move a ship and/or an airplane. By virtue of the spinning in water or by air, this produces thrust and that in turn gives movement to the ship and/or airplane. Here we are going to talk about a wooden propeller made out of sticks. However, it must be noted that it is quite a challenging task and must be done with proper attention and care.

To make a propeller, the things you will need:

• Craft sticks
• Glue sticks and hot glue gun
• Sand paper
• Drill
• Screw nail
  

1. Take three craft sticks crossing each other in a manner that they intersect each other at a common point and form a model similar to a small fan.
2. Using the hot glue, join them together at the common point where they touch each other.
3. Next, file the edge of each stick in clockwise direction so that it is slanted on every blade.
4. Continue the process of filing with the top side of each blade until all of them are slanted.
5. With the aid of a drill, pierce a hole through the common point of the three blades. Secure these together with the help of a screw nail.
6. Make sure that the propeller spins smoothly through its axis. Blow on the propeller to see that it spins.

Tip: Be very careful while applying the glue to see that it does not run into the hole and thereby interfere with the smooth operation of the propeller. It must be noted that a fibre glass/epoxy propeller is heavier than a wooden propeller but lighter than a metal propeller. The weight difference may result in different vibration characteristics. Also, a composite propeller is much stronger than a wooden propeller. It might be a good idea to base your propeller upon a model propeller purchased from the market rather than setting out to making one on your own without any concrete steps to follow or without any specific model to chase.
