Hi John,
it's obvious that, in my example, the points that mark the time
and that are on adjacent circles are not "logically" connected, that is the
line that we obtain in connecting them it's not an hour line (strictly
speaking).
But we can join them with a line ( that has only an aesthetic value ) to
make the reading more easy and the single point less lonely.
In these lines only the points in which they cross the circles have a real
meaning.
In any case this kind of sundial is not easy in use !
Gianni
P.S.In my drawings one circle (the last) is missing for an error in my
program !
