The Megalith Movers Prehistoric Engineering
Blog 28th November 2015    On Monday with the first section of the new nine inch thick fulcrum already in place, I set it in the correct position and slid the first three levers in place. I then, with Steve's help put the second part of our new sectional fulcrum in place, and after some trials and tribulations that day we accomplished our best ever single lift of about four inches. Considering that a few weeks ago we had been happy with a single lift of one inch per day this was something to celebrate. The photo below shows the scene at the end session on Monday morning.    Tuesday I continued experimenting with my new idea, and with the weight of the obelisk supported by the two fail-safe towers, I cut the first of the new sectional fulcrums in two. We then set these two sections of fulcrums and levers in place for the next lift, which meant that just the empty levers provided enough lift to release the pressure on our remaining fulcrum. I then cut this last section of fulcrum in two, and set the levers on each. We now had a fulcrum comprising of four separate sections, each of which provided a pivot point for three levers. A little like a four cylinder car engine, for the sake of clarity I will now refer to these separate sections of fulcrum as I would if talking about a car engine, namely cylinders one, two, three and four. As we had previously completed a lift using only six levers, I suspected that we could easily achieve a lift by loading the sand-bags using just three of our four cylinders. I loaded the sandbags on cylinders one, two and three, this gave us an excellent lift of about four inches. With cylinder four unused I was able to roll the fulcrum forward and set the levers on cylinder four. See photo below.    Wednesday with cylinder four moved forward and its levers not bearing any weight, it was a simple matter to transfer the sandbags from the levers on cylinder three to the levers on one, two and four. This resulted in a lift of about one inch and enabled me to remove the levers from cylinder three and roll it forward also. We repeated this procedure with cylinder two and gained another inch. We were then able to do the same with cylinder one. Four inches in about half an hour, I found this method remarkable, simply because we no longer had the need to pack the fail-safe towers, which we did of course just to be on the safe side. As we unloaded cylinder four I realised that I could not roll it any further forward as it would have rolled off the end of small crib, so I removed it and raised part of the crib six inches. When I replaced it, it was back were we started, but six inches higher. This stuck me as truly remarkable, we were building a staircase as we walked up it!    That evening I gave the remarkable events of the day some thought. And by the following morning had a clear plan of action on how best to capitalise on this new realisation.    When I arrived at Steve's place next morning he was already hard at work, two new ladders had materialised overnight and he was now erecting another section of scaffolding. “When did you do all this?” I asked. “Mostly yesterday afternoon, I'm now back on my one cigarette an hour routine and if I keep busy I don't keep looking at the time.” he replied. “Well you've done a fine job with the ladders and I presume the scaffolding is for packing the first fail-safe tower.” “Yes,” he replied, “I can barely reach off the steps any more, it's getting dangerous.” “Well take a break for now, I want to discuss a new modus-operandi.”    I outlined the plan to Steve. We would completely dismantle the first fail-safe tower while the loaded levers and second fail-safe were holding the obelisk, and in the space gained erect another section of scaffold (stone staircase) underneath the obelisk. We can then build a small crib from the top of this scaffold, up to the obelisk and pack it tight. Thus making a new first fail-safe, this would also gain us a great deal of of spare timber, something we were getting short of. With the weight now on the new first fail-safe, we could unload the levers, remove the fulcrums and incorporate the fulcrum supports with the second fail-safe. As the obelisk rose we could extend the crib, and roll the fulcrums forward at will. Steve was in agreement and by the time we finished on Thursday we were almost ready for the fulcrum to roll.    Friday morning, Steve was again busy finishing the working surface of the scaffold as I arrived. We could now walk about on both sides of the obelisk, and also at the end. I finished setting the levers and we began lifting. Once we had all the levers loaded, we began what turned out to be one continuous lift, as one fulcrum was loaded, this freed the next, so that it could also be rolled forward and reloaded. All I had to do was transfer the sandbags from one lever to another. That morning we achieved a lift of about six inches, our best day yet. I moved the bags, and Steve was fully occupied packing the fail-safe towers. Had I been a much younger man I could have continued all day long, but two hours was about the best I could do at my present age. I called a halt and Steve took a couple of photos of the progress.
