OK, I'm kinda screwed on my approach options. The tower kit (N scale) is the first kit I ever built and thought that more glue is better. I cannot get anything apart without major damage to the structure. So, I'm going to have to use the already built tower as the center point, and build up around it. I've got several structures I bought at a train show. They are sacrificial so I'm going to to see what happens when I use parts of them. I'm going to try to use some parts from at least four other structures, not including the tower. Here's my starting source of parts.
