Good morning Philip

There are a couple of versions of a bowstring sundial in the September 2004 addition of the Blacksmith's Journal #164. I have not attempted to build it; however it is on "The List". Issues are downloadable, some clubs have copies to check out, and I have found them in public libraries, I usually needed to use inter library loan.

Take a look at a Analemma sundial.
It looks like a figure 8 sketched on the floor or other surface.
It reflects the march of the sun on a rotating (inclined) sphere in elliptical orbit

They are a little easier to build and you can have a lot of fun with the numerals as you can really spread this sundial out to cover some square footage.

The gnomon is usually vertical
