1. In my opinon this is a top 10 tool to have. This is a pop dimpler that you will need to dimple in tight spots. This is a must have.
2. I use the micometers every time I start a new riviting section. $15 Harbor Freight
3. This is a Debur tool that I have put in my Electric drill. This is not recomended untill you become very comfortable with the build process. NOTE, it is slower to use the drill to debur than it is the actuall hand tool.
