Cut the top Boot Cowl section to fit around the cabane vee tubes. This is the piece between the firewall and the instrument panel at the top.
I decided to just cut the panel to fit around the tubes, instead of making elaborate pieces to fit around them that are easy to remove. Although this panel is removable - I really don't plan on removing it for a very long time once the airplane is finished. So I don't need this to be all that easy to do.
I just cut slots at the front and oval holes to clear the tubes. I spent a lot of time measuring and marking, and actually measured the angle between the tubes and the panel to calculate the shape of the oval accurately. I laid this out on cardboard first, and cut it out. I did mess up the first pattern with a boneheaded layout measurement mistake, but I got the second pattern laid out correctly. I realized it as soon as I cut it out and looked at it. I know that nobody would believe it, but the second one actually fit great the first try! One of the benefits of being an engineer I guess.
Once I transferred the pattern to the panel and cut it out, I just had to do a little filing of the holes to get the clearance that I wanted. Otherwise it worked great.
