I would like to suggest that if you use a pin-hole, that the aperture be parallel to the dial face. This may seem obvious, but it wasn't obvious to me 2 years ago. This way a round hole will always cast a round image, and will not spread into an ellipse as the angle of the sun changes. I support your thoughts about mounting the gnomon in a manner that permits adjustment (or replacement). If, after installing the dial, it does not read precisely right, it is a good thing to be able to "tweak" it into perfection. Bill Gottesman Burlington, VT 44.4674 N, 73.2027 W
