Now that I have all the lines that rap the dome to the same height as my 300 dome I taped this old dome layout on the floor. The straight up and down lines on it are still in the same locations as the 300.
Setting the R3 dome on the drawling and centering it, I marked all the lines on the bottom then drew a straight line with the template that connects to the top center pin.
Here are some of the lower panels on one side after being taped off.
And here is the other side.
This is a straight on shot where the eye will be. The small panels under the eye will be next.
