Description:
  • This is an adaptation of the dual cylindrical sundial design by Hoffmann Albin of Butgenback, Belgium that provides for two separate dials to be displayed. In this variation, the two dials are separately displayed after being rotated and locked into viewing position every six months on the solstices. Except for two bronze sleeve bearings, all parts are 304 stainless steel that has been glass bead blasted to reduce reflection, machined, welded or laser cut. The analemmal hour lines, equinox and month lines are laser etched into the stainless steel dial plates. The dials and their supporting cradles are 12 gauge with 12" diameters. The post is 1.75" in diameter.

    "I wanted it to be a building project, as opposed to simply buying and installing a finished dial. For me, the more time and effort I put into a project, the more satisfaction and enjoyment I get out of it...Of all the commonly available metals, I thought stainless steel would hold up best to the elements....I hoped that those who know nothing about sundials would at least be curious enough to ask what that thing was and, maybe, how it worked. And for those who know more about sundials, they would find the design both eye-catching and intriguing."

    Dial shadow readings are discernible and accurate to within +/- 15 seconds EST.
