I would like to thank Roderick for the solution, and Frank for pulling my leg. I
appreciate that ...
While taking a walk this morning I thought that it would work with an equatorial
dial, but I did not get far enough to realize that equatorial gnomons would do
the trick.
But the dial I had in mind would be vertical and facing south-east, and I can
see no way, with my limited abilities, to get the angles of all those gnomons
right. Any ideas?
Dammit!
