Members of the University Carpenter Shop move the Joseph N. Pew sundial off the Engineering Quad to prepare it for minor repairs.

The Joseph N. Pew sundial, which normally occupies a corner of the Engineering Quad, has been moved to the Clark Hall Machine Shop for repairs and minor modifications.

Designed by Cornell President Emeritus Dale R. Corson and mechanical and aerospace engineering Professor Emeritus Richard M. Phelan, the sundial is in need of slight recalibration, routine maintenance and a few general design improvements, according to Stan Carpenter, associate director for technical services for Clark Hall's Laboratory of Atomic and Solid-State Physics.

Corson will be supervising the sundial project, Carpenter said. Crews aim to have the 26-year-old icon, reputed as one of the world's most accurate sundials, back on the quad sometime this fall.
