I'm so glad you folks have enjoyed this thread.
Here is a photo of my new hose and pipe in my basement, the patchwork I did on the backdrop behind it, and the crane and steam shovel I placed in the vicinity:
I may replace the construction vehicles with a structure or two that is the right shape and size. I will keep a look out for them at my LHS and future train shows, which will be fun to hunt for.
Of course, the thought occurs to me to paint the black hose and white pipe. I would appreciate input from you folks about that, but I'm inclined not to do it. Maybe I will turn that area into an oil refinery of sorts in which the hose and pipe can kinda blend in. Arnold
