Hi Gianni, Constructing a monofilar sundial on Warren's wall will do well. There isn't a relation to azimuth anymore, however the dial looks good.
I have a question about the 2 drawings you sent. In your text you wrote you used 2 different styles for the 2 dials, one vertical, the other horizontal. I get the impression that in both dials the style is the same and vertical with angle of 45 degrees to the wall. Is this right? Best wishes, Fer.
