This was an easy toy to build. Of course, it's non-functional. But it looks like it could work.
As I near the end of this project, I find it increasingly difficult to get these pieces to stay together. The fiberboard washers are a little worn, so they don't grip the girders tightly. Every time I adjusted one part of the frame, the other would start to come apart. Good thing there are only six more toys to build!
