One of the modelling challenges I ponder regularly is the logistics of taking modelling output (hypothetical though that output might be) to distant events especially those involving plane travel. I can’t see putting any non-trivial structure or diorama in a checked bag which means you are wanting something that qualifies as carry-on.
At major events featuring modelling contests, there is often a diorama contest with limited space for just such travelling modellers. I have seen square foot, a ceiling tile, peanut butter jar lid, 2×2 inches, and so on. One I have not seen yet is the shelf insert or “book nook”. The basic format is a roughly book shaped box diorama viewed from the narrow edge while inserted among books on a shelf. I didn’t want to pirate anyone’s photos so here is a link to a BBC article on the subject. If you search online, you can also find numerous photos of fascinating instances.
Many of the existing instances are variations on a view into a narrow alley framed by structure faces depicted against the inside of the box. Usually some sort of lighting is included. It occurred to me that I know of a bunch of folks who like to model structures… I also see why there couldn’t be rails running up that alley since even modern O scale (1/48) horizontal minimum clearance is about 4.5 inches. Giving it a bit of thought produced an extensive list of possible ideas.
Why wonder about this when I have a layout already under construction? If the blog title didn’t warn you already, I am not the most laser focussed person when it comes to modelling subjects. Such a format offers a change to try out all sorts of techniques, materials, scales and eras that do not fit within the primary project. The book nook format would also solve the question of where to put the non-conforming item once completed. Leaving aside the problem of having bookshelves already stuffed with train books, of course. 🙂
