This is why I have 17,342 pounds of tools

------------------------------ Welcome to my shop. Today we'll be designing and building nine different ball bearing launching catapults. Why? Other than being a lot of fun, the catapults are the perfect vehicle to show you all of my major tools, how they work, and why I have them. I had fun making these, I hope you enjoy them too.
