Now that I have experience on the pilot's side, I began cutting the opening for the copilot's side. I did a rough cut of most of the flange. With the flange out of the way, I could finish drilling the #12 and #19 holes and countersink them for their screws. Then I marked and trimmed the inner door half. It was a rather social day at the hangar as the lift I found for my neighbor was being installed and then several people stopped by to see my progress.
