Blender tutorial | Modeling And Driving Gears Of Different Sizes In Blender

How to build Gears of different sizes in Blender 3D and have them work together.
 
Recently I completed a small modeling project where I needed to create some gears for a catapult. 
 
I’d like to share my method for creating, calculating and driving gears.
 
Please let me know if you have any questions in the comments below, or if there is a section of the video you want me to expand on. 

Below the the original file. This includes the three gears, the drivers and a short animation. ​
