Powerful mini Cannon - Make a mini Cannon - MWIG

Dear friends,
Welcome to Meanwhile in the Garage.

This video is for Educational and Demonstration purposes only!

Since childhood, I had an idea to make a miniature cannon, although so much time has passed, but I still had this idea.
So I decided to make a miniature Cannon. It can shoot by the way.
In order to make such a Cannon, you will need a whole workshop, a lathe, a milling machine, several weeks of effort.

If you have any crazy ideas or suggestions, please write them down
