The lever on the left is the one that I tried drilling free hand. I suck at anything freehand, fortunately I am good at making fixtures. Once I made a simple mill fixture I turned out nine use able perfect pieces!
Here is a completed lever. This is for the de compression and mag advance.
Here is the bung that I made for my gas valve. It turned out well. I am using a 1916 to 1939 petcock.
