Here I started cutting out the F-792 rudder stops.  I am getting fairly proficient in drawing up simple shapes in CAD and generating the G-code to get them cutout with the mill.

I am not sure why Van's has you trim the one end of the angle like this, but I am sure that it will be become clear later in the project.

Cutting the angles in the angle....

What is great about the mill, is that dimensionally, I can get it more accurate than I can by hand. Additionally, once I draw it up, I can cut each one out the same as the next.  The left and right rudder stops are essentially the same.
