One of my goals for the cabin is to have an example of each of the major types of sundials somewhere on site. During a recent trip, I experiemented with a layout for a reflected ceiling dial inside the house. It didn’t work well in the living room because of the vigas (not a flat surface), but the sunroon looked promising.


As you can see in the photos, the beam of light is quite bright, and during this visit, we actually had fun guessing the time by the placement of the light. Lots of jokes about the time being “window thirty” or “half past the pipe”.

If you want to try making your own dial, it isn't difficult. You will have to polish your geometry skills, but the projects are straightforward. Sundials: Their Theory and Construction by Albert E. Waugh is my favorite book about making dials. It's out of print, but still available through Amazon. Try looking for it at your library.
