Are folks here using facebook? That would seem not only a great way to find
one another, other than this targeted, topic driven list, but also a great
place to post pictures of work as well as work in progress.
For anyone interested, please feel free to send me a friend request
mentioning dials
I heard that the US government will be conducting an experiment with the US
power grid that will possibly cause all traditional electric clocks to run
twenty minutes fast. According to Homeland Security:
"Beginning in July, electronic clocks in the United States could begin
running as much as
Well, Tony and Simon have been very encouraging as have the rest of the
list. I don't really KNOW what I am doing but, I went ahead and printed out
a drawing from Shadows and transferred it to some leftover copper flashing.
Hubby is going to cut me a piece of wood on which to mount the copper.

Ok, I have a question about the Shadows program. it takes in the longitude
and latitude when you set a position to design the hour lines on a dial.
What I wonder is, does that give you a dial that shows the official time
when the dial is set or one that shows the sun time?
In my case, I am in
Ok, I have seen all the equations. And, since I am more years from college
than any woman my age will admit, I am going to skip that for now and go to
concept.
So. latitude determines the height of the gnomon. You are going to use a
right angle for your gnomon and the top of that triangle is de

A good sundial indicates only solar time.
For standard time and daylight saving time we have a watch!
The sundial is the only simple instrument that can indicate solar time.
Changing it to indicate standard time is similar to an astronomer who turns his
device to indicate the sidereal time
I did find the toggle that allowed me to have the dial correct for
longitude. That may make a difference. Basically, where I live, my solar
time is central standard time rather than Eastern Daylight.
I am not sure If you can answer this or not. Do the time zones match solar
time at the easternm

I have the impression that you have not understood my message.
Make a sundial for solar time
That means, when the sun is in the south the sundial indicates 12:00 am
All your questions then are irrelevant for the construction of the sundial.

Hi Karon:
I must respectfully disagree with my friend Willy that "a good sundial
indicates only solar time". By that definition, all my sundials are bad
sundials (ouch! That hurts!)
I understand his traditional point of view however. Many British and French
dialists feel the same way as W
I apologize for the level of my questions and the damage it may have done to
the forum.
I am certain that the ancients did not use high end geometry and trig as the
geometry and trig formulae we use today. I simply thought there were graphic,
geometric relationships and ratios that were a bi
Hi Karon;
Don't let that guy bother you.
The way I see this list is that there is an owner or a
sponsor of the list but everyone else is just a guest and we
are all equal, including you and I and the Professor Alfonso.
I'm a newbie myself, with zero math skills but the members
of this list h
But, see, here is where you make the mistake. Not every craftsman had to
understand the higher math, even if they practiced it. a builder could build a
straight, tall wall without understanding gravity beyond a plumb line. He could
level a basement floor simply by knowing that he would flood an
Good for you Karon! You are right!
One doesn’t need to know any higher math to design a great sundial. There are
easy ways to design them nowadays- especially with great sundial drawing
programs like Shadows Pro and many others. You just have to know enough about
dialing to get your
Karon,
I am enjoying the discussion your comments have started. Perhaps this
has already been suggested, and I missed it. But, I would recommend a
browsing of Albert Waugh's book "Sundials, Their Theory and
Construction," published by Dover Publications. It is available via
Amazon for about
Thank you John. Thank you Karan.
You struck a close and resonant note with me.
I remember when I told John Carmichael that I laid out vertical dial designs
with graphic methods. He politely said, "How quaint" and suggested I use
Shadows Pro to generate the required geometry. Oh thank you, John
