Technical and Technological Considerations in the Carving of Granite Prisms by High Pressure Waterjets


In February 1985, the University of Missouri-Rolla was recognized by the National Society of Professional Engineers for the creation of a new version of the Ancient British Megalith known as Stonehenge. The UMR Stonehenge stands some 5 metres high on the northwest corner of the University of Missouri campus. The monument comprises some 53 stones, each carved in their entirety from granite prisms transported from Elberton, Georgia, using high pressure waterjets. The entire cutting operation was completed with a single rotary swivel and, in large measure, with one high pressure pump. In order to achieve the cutting of the UMR rock which required exposure of some 2700 square feet of new surface it was necessary to improve the penetration rates achieved in tests in the 1960s. While much of this development work took place some years ago, it is perhaps of interest to review those findings at the current time and demonstrate their application and use in the construction of the current monument.
