Dear Frank,
For your question 3: Could you be designing a vertical dial for an interior
south
facing wall with a 'Velux' type window (or any rectangular glassed-in
section) in the sloping ceiling above? I would have thought it would work
and could be as attractive as you cared to make it! But I am not sure if
that adheres to your spec of being in the noon gap unless you accept the
glass as being a conceptual underslung gnomon.
Alternatively could one use an unsupported sloping porch roof as an
underslung gnomon, with the delineation in the area above the door? But it
would not be very weatherproof with no sides to the roof!
Happy New Year,
John Foad

Subject: Gnomon Gap Puzzle
Dear All,
Here is a little Dialling Puzzle to start
the New Year...
We are all familiar with the term 'Noon Gap'.
On a simple horizontal sundial with a plate
gnomon, this is the gap on the dial plate
between the two vertical faces of the gnomon.
On the dial plate, there are two lines for
12 o'clock with the noon gap between. Often
this gap is left blank. Sometimes there is
a date or, perhaps, the maker's name.
During the year just ended, I was asked to
design a dial which had to fit in a rather
unusual space. After a little thought, I
decided on a solution. In this...
THE ENTIRE DIAL FITS INSIDE THE GNOMON GAP
Question 1: What does the design look like?
Question 2: Can this possibly look good?
Question 3: What is the 'unusual space'?
A Happy New Year to you all.
