|I modeled Dayton Ave. Tower with pieces of sheet styrene, applied in layers to get the various depths. Since this was a poured in place concrete structure, I scribed lines with the back side of a hobby knife, which makes raised lines imitating the concrete that squeezed though the form boards. The outside stairs were the most difficult since they are made entirely of styrene strips, sheets and tubing. The lettering is recessed into the actual tower but I used dry transfers. Windows were cut down Grandt Line, or made from scratch with styrene strip. In a very old Model Railroader article on making this same tower, with elegant drawings by Linn Westcott, the tower was made from bass wood and the windows were made from painted chicken wire! Unfortunately I never saw this article. After I built mine, blueprints were published in the Steam Age Common Standards Volume 4. But I had to measure the tower and make my own drawings (which was actually kinda fun).
