The “Clapp Trapp” was easily folded up into a 14 inch high stack of folded panels measuring 2 ft × 4 ft and weighed only 125 lb. It fit into most larger vehicle trunks. (Courtesy of Doug Clapp). 41. The “Clapp Trapp” walls were hinged in pairs allowing them to be self-supporting during assembly. They hooked together to form an octagonal structure which supported the roof. Note the smart use of “pouches” to hold accessories on the inside walls. (Courtesy of Doug Clapp). 42. ” To follow the motion of the stars, the roof is simply lifted off slightly from inside (it weighed only 25 lb), and rotated into the proper position.

Normally the metal pier top should begin about 2 in. above your observatory floor. For comparison, the faint image of a foundation Sono-tube footing is aligned at its exact height illustrating where floor joists would sit in the bracket on the top. From this you can visualize that the steel pier base rests about 2″ above the finished floor surface. (Diagram by John Hicks).
