Hello All:


Thanks to Robert Terwilliger, I'm finally able to show and tell you about a
beautiful new rare sundial that I made especially for debut at the NASS
Conference in Tucson.



During the past year I became very fascinated with Analemmatic Sundials. I
researched all the websites and literature that I could find that pertain to
this type of sundial.  Unbelievably, I could not find a single example
anywhere of a mid-sized analemmatic that one could put on a pedestal.  I
found photos and description of tiny pocket analemmatics and large human
size analemmatics, but nothing in between!



To me, it's a no brainer. Table Top Analemmatics are a wonderful alternative
to traditional horizontal sundials.  I've always thought that sundials that
can be used on pedestals are the most commercial types because they don't
need special mounting brackets and declination measurements like wall dials.



This sundial is also rare because it is the first sundial that incorporates
Roger Bailey's now famous Seasonal Markers (Bailey Points I call them).  I
used a very rare and beautiful type of sandstone called "Picture Rock" from
a secret quarry somewhere in Arizona.  Rumor has it that the quarry was
closed so I may never get another slab of it again.



I redesigned and retooled the gnomon since the conference to make it much
more precise. 1/32" tolerance allows you to place the gnomon to the exact
date since the clockwise dateline is divided into clearly marked weeks!  You
can see why I wanted a spiral drawing program for the gnomon legs.  The
gnomon is not connected to the face and is moved like a chess piece. (But
I'm working on a sliding attached gnomon design which I may or may not use
in the future.)



Note that you can determine solar azimuth if you place the gnomon in the
center of the 16 pt. compass rosette instead of on the dateline.



I used Fer de Vries' Delta Cad Macro to design the face and Roger Bailey's
Excell Spreadsheet to verify location of the Bailey Points and the minimum
gnomon height (So that the shadow reaches the noon mark on the summer
solstice.



Hope you like it!
