The sundials shown on this page were created by the Science Technology Centre of the Carleton University in Ottawa, Ontario. The following is quoted from their website.

"Over the past three decades, Carleton has built up a world class Science Technology Centre (STC) to support research at Carleton and provide engineering and technical services to a wide variety of external clients. One of the largest centres of it's kind in North America, the STC employs 40 highly skilled electronic and mechanical engineers, technologists and technicians, who provide comprehensive technical expertise from design to final assembly in areas ranging from precision mechanics and printed circuit boards to complete electro-mechanical systems with custom software."

The site has a lot of interesting information describing their capabilities. Visit them at : http://www.stc.carleton.ca

The sundials were constructed in their Computer Numerical Control (CNC) Lab. All the geometry and programming for the CNC milling centers was created with Mastercam (the lab's Computer Aided Manufacturing software).

The horizontal sundial shown here began as a "30 Years of Great Service" momento from the staff of the Science Technology Centre to the Director. The dial is made of 1/4" solid brass. The base stone is 6" thick and was obtained from a local quarry. The brass eagle was purchased at a flee market. The dial is located in the Director's back yard.
