My air traffic control tower is now more or less finished. Here are some more work in progress shots.
First the process of adding glazing bars to the windows of the top floor. I used Slater's Microstrip for the three flat glazing bars on each side.
Then I made some L-section by glueing two pieces together with liquid polystyrene cement using the corner of a wooden tray (the one previously seen holding my recent 6mm purchases) as a jig. Cut carefully to length these formed the corner frames.
