Sundial Cupolas

[John Carmichael]

Hello All:   I'm considering building or buying a four-sided painted wood cupola with a copper roof for the roof of a home. I'd like to put a sundial on each face of the cupola and then a neat weathervane on top.  I've had great fun searching for cupolas and weathervanes online.  There are and endless variety of styles and available.  Most of the companies that sell cupolas also sell weathervanes.   Here's a photo of one of the windcup weathervanes I like: http://weathervanesofmaine.com/weathervane-wc9821.html   And I'm thinking of a cupola that would look something like this (Glassed Mahogany Pagoda with 701 Finial Image 2), but with sundial faces instead of windows: http://www.weathervanecupola.com/cat/cupolas.html   Have any of you ever seen a cupola or "clock tower" with sundials instead of clocks?   John   p.s.  Do you think the copper weathervane will act like a lightning rod?  Maybe it should be grounded?   p.p.s A lot of the weathervane websites sell marvelous copper finials that a dialist could use for perpendicular gnomons.
