Here are a few of photographs of my new 32" oval shaped stone analemmatic sundial on a pedestal. After scouring the analemmatic sundial links in both the NASS and Frans Maes websites, I was unable to find a single example of a "table top" type analemmatic! Every single analemmatic that I find on the internet is large people size. I think tabletop versions are great! And actually, they are easier to make than horizontal dials because the gnomons are simpler.
I used Fer de Vries' Delta Cad Analemmatic Macro for the date lines and hour points and Roger Bailey's Analemmatic Spreadsheet for the east and west seasonal marker locations and gnomon height calculations. The 2" thick stone is a very rare hard-to-get Picture Rock Sandstone from a secret quarry somewhere in Arizona. (Since rumor has it that they closed the quarry; I may never get slabs of it again). The inlayed fittings are either 24 carat gold plated brass and tiger eye stone spheres. The oval dial face measures 32 inches by 20 inches and weighs about 80 pounds. The gnomon is 14 inches tall. I have never seen a "table top" metal or stone analemmatic so I thought people might be interested. The dial also shows solar azimuth if you place the gnomon on the center of the inlayed gold 16 point star at the bottom.I made it especially for debut at the NASS conference. |  |
