Hello Everyone
I really like the drawing you made John for your customers
- it helps a lot. Thank you.
Thanks Tony for the picts and Powerpoint presentation - it
is wonderful.
Thanks Chi-Lian and Linda for your comments.
After reading the advice I have received, I think that I
will make my date scale the conventional way - although I think the analemma
looks way cooler! It looks as if the first day of summer and the first day of
winter are at each end of the scale. Is this true always? Also, does one stand
directly on the centerline, or on the month "block" which falls to the left and
right of the center line?
More on my previous obsession of using the figure 8 in the
date scale:
If I am not mistaken, an analemma, on the ground for
instance, can be made by marking the position of the sun (cast by some point) at
the same time for a year every few days or so. I am referring to the
website: http://www.cerrilloshills.org/analemma/path3.htm So,
if I were to mark the path at noon, local time, for a year, the figure 8 should
fall on the N-S line? It appears as though the months outlined on the figure 8
match the date scale in placement except at the top portion of the figure 8
where the months seem to flip from the left side to the right side. I can't help
but think that the straight line date scale mimics the analemma in month
placement. That's why I figured that I would make the figure 8 instead of the
plane straight line. Also, I thought about positioning some type of gnomon that
would cast a bright spot (or shadow) on the date scale which could follow the
figure 8 path exactly (at noon) just like the noon analemma sundial featured in
the website above.
I am fascinated by the analemma and would love to somehow
use it in my sundial, however, I definitely want my sundial to be correct and
accurate - no false sundials here! But I keep seeing the analemma used as a date
scale in pictures on the internet. One I found looks like it is bronze.
If I shouldn't use the analemma in the date scale, where
could I put it in the sundial properly? Or, should I just make a separate noon
analemma sundial like that in the website referred
above?
