The Unfinished Obelisk At Aswan A New Erection Theory by Gordon Pipes    With our present ten ton back yard experiment looking increasingly likely to prove successful and planning fairly advanced for our next step, which will be the actual erection of a fifty-ton concrete replica obelisk. I would now like to use the knowledge gained to present a practical theory for the erection of the one-thousand-ton unfinished obelisk, which still lies in the quarry at Aswan. The Theory       Once the obelisk as been delivered to the required site (see stone-rowing, the obelisk is raised horizontally and the base positioned over the turning groove on the plinth. Now the levers we used for the stone-rowing and the initial lift and positioning, are concentrated each side of the obelisk and at the top one third. This will be well beyond the balance point of the obelisk, but not near enough to the top to interfere with the lifting beam as used in the ten-ton experiment. This lifting beam is then set under the top end of the obelisk, and levers positioned at right-angles to the existing levers. Operating all the levers in unison, the top end is lifted and packing inserted under the obelisk.    As the top end rises a few inches at a time, the packing is moved forward, and a short length of fulcrum at the top end is raised as necessary. As the obelisk is now out of level with the ground, the side fulcrums start to take the shape of a stepped fulcrum, with thicker fulcrums at the top of the obelisk, and thinner fulcrums nearer the base. Once the top of the obelisk has reached a height of about three inches above the starting level (the height of the plinth), the obelisk is packed tight, the top fulcrum and levers removed, and a block of stone about the height of the plinth is rowed under the top end of the obelisk.    The top fulcrum is then placed on the stone block, and the levers are inserted over the fulcrum under the lifting beam. The lifting continues, and as the centre of gravity shifts down the length of the obelisk, the side fulcrums and levers are slowly made redundant. See sketch below:    See also photos below of our ten-ton experiment with the lifting beam working with the levers, and steel scaffolding representing the stone blocks.    In the first ten-ton experiment the side levers were not used, but would be needed on any obelisk above perhaps two or three hundred tons.    To test the practicality of this new theory, we will erect our proposed fifty-ton experiment using a lifting beam of roughly the same size as in our ten-ton experiment, which will be almost certain to break without the side levers taking some of the strain off our lifting beam. Thus proving the validity of the unfinished obelisk theory without the need to actually erect such an obelisk. return to top of this page
