Andalusia Alabama USA Reflective Equatorial Dial 894
This dial is one of Bill Gottesman's uniquely designed Renaissance dials of cast and structural bronze with a 27 inch diameter time telling helix whose axis is aligned to the celestial-north pole. Time is told by a focused beam of light from a long cylindrical unsilvered mirror situated on that N-S axis, reflecting sunlight into a slit of light onto the helix, telling time throughout the day. A sliding time scale within the helix is adjusted for longitude, date's equation of time correction and daylight saving time. Once this scale is adjusted for date, the dial shows civil (local clock) time with an accuracy of under one minute. The dial base is cast bronze that allows adjustment for latitude and is placed on a sandstone plinth.

Opp Alabama USA Equatorial Dial Dial 895

Wallace Community College, under the guidance of Eddie Spann, instructor for diesel and heavy equipment and designed by the college president, Dr. Herbert Riedel. The stand is a crankshaft from a Cummins engine, while the dial base and dial faceplate are flywheels. The gnomon is a heavy duty diesel cylinder liner puller. The gear teeth on the faceplate mesh with a small gear to allow easy adjustment for the equation of time. Hours are marked by bolts, and on the winter side are painted hour numbers.
