Those people on the Internet who say that the Egyptians moved pyramids with bottle jacks and blocks of wood have probably never done it. It is amazing how just half an inch of drop can cause a spectacular chain of events. I had a neighbor who personally saw a man get crushed when the crane wheel hit a tiny irregularity in the pavement that nobody saw. Even worse, the boss threw a tarp over the body and ordered the crane driver to keep moving. How does one avoid this kind of accident? My lathe setup is not susceptible to this problem, and I am glad now. The person who moved it told me that the bench was much heavier (and more dangerous) than the lathe. Fortunately, he had a good cherry picker, lots of straps, and a truck.
