Living very near 45 degrees north I have noticed that horizontal and
vertical dials have the same lay out (obviously, since lat=colatitude)
Are there any other designs which would have some special property at 45
degrees? I'm interested in any special properties at all, no matter how
trivial.
on the reasons for your conclusion.
Thanks

However, the good news is that in your email program there is a way to

In the list archives I ran across a post by a man named Hough. I don't
recall his first name but his email was shadow@ somewhere or the other.
The post was in reference to a PostScript program for reclining and
declining dials.
Mr. Hough, if you're still around I'd sure be interested in seeing
in a difference in distance of 3 cm on the data scale and a
difference in read time
of several minutes.
That is to much for the oldest an most accurate scientific instrument.
Who gives us precise values for the sun declination?

Hi Steve,
I just printed out your scadd sundial. It's nice.
Regarding the topic of getting fonts to print out the way you want them
to, PostScript has a command that turns a charcater to a just another
path. It should be possible to do that and then turn it into dxf.
Then it should be possible
Fellow dialists,
I've revised my webpage and finally managed to get the output of my
PostScript sundial programs into the gif and PDF formats so if any of you
tried unsuccessfully in the past to see them I invite you to try again.
I have also added a dial or two.
Happy spring and happy
sundial specific.
Best,
John

Dear Dialists,
My PostScript cylinder dial program (http://www.cyberspace.org/~jh/dial/)
was, it pains me to say, wrong. Sorry. I hope nobody used it to determine
the time of anything more important than lunch. If you downloaded it
before xmax eve please recycle it and download a new one.

I have (with help) uncovered a few bugs in my postscript dial programs;
* I (generally) mark only sunny hours in the northern hemisphere--I
apologize. I'll fix it.
* The capuchin dial was chopping off some of the curves for some lats.
It's fixed.
*The equatorial dial crashes if the mottos are
I modified my cylinder dial postscript program and made a perforated
ring dial program.

Daylight savings time is gone!! HOORAY! I'm sure lots of you love it but
not me.
To celebrate I've put another postscript sundial program on the web. This
one is for a Cylinder dial. It's not interactive yet. By next week you'll
be able to submit your latitude and the height and circumferance of
because I don't have permission to run cgi scripts there yet so
it's all rather messy.
Anyway, sorry, and I'll have it straightened out, or at least improved,
soon.

Maybe I'm old fashioned, but I really think that sundials should be built to

Fellow dialists,
I have rewritten my equatorial dial in native postscript and I think it is
much improved. It is also available in PDF but PostScript users can
change the motto and include a longitude correction or even change the
design substantially by changing a few parameters.

Now I see my mistake. The curve isn't an arc. Since I only have the
two main date arcs, which do have the same radius, I spaced out the
obvious fact that the other curves would have smaller radii.
The arc does hit the two date arcs very near the right place, though. It's
just not flat enough in
Upon further consideration of my question about the shape of that curved
line on the Capuchin dial I see that it is of course an arc.
