New Pictures of Wenger Sundial

1999-03-02 Thread Daniel Lee Wenger

Dear Fellow Dialists

I promised photos of my newest sundial and they are now on my web site. A
set of pictures is at

http://www.wengersundial.com/dialPicture.html

The photo at

http://www.wengersundial.com/dial1.html

shows the detail of the analemma and the scribed features of the dial.

This photo is relavent to the recent discussions of analemmas and their
placement on sundials.
On my globe the significance of the analemma is apparent. Each analemma
represents the geographical
position of the sun at mean time 6, 7, 8, 9, etc. for each day of the year.
In fact the geographical
postions of the sun at those mean time hours would be a collection of 365
dots but the analemma
is interpolated to generate a semi continuous curve. Since the set of dots
that would be generated during the following year would be slightly
different the curve used represents some sort of average
of the dots over a four year period.

The generation of an analemma on another type of sundial involves a
projection of these geographical positions
through the origin of the globe onto some surface, usually a horizonal or
vertical plane.

The photos are detailed and my take some time to download.

Hope you enjoy them.

Hello dialists,

May I bring your attention to my new web pages showing pictures
of my Wenger Sundial. The models shown were made in the 70s. I will
have photos of my new glass version in January. I have wanted to make
this sundial in glass since the 70s but did not have the resources until
now. Have been working on the laser programming and jig design for a
year and have now my first glass version.

Hope that you will be excited by the design.
