>>138004 Not completely tru. The Dutch postmill for example is the oldest type of mill known in europe and is also the most complex one. The whole machinery is located in the top building which rests on a single post to allow it to reposition into the wind. The enourmous forces on the post are deflected into pull force by 4 pairs of diagonal beams who send the force to 2 crossplates. This whole construction has proved cheap to build, and had a great endurance. This mill still has its wooden parts from 1684. The parts are not fixed by nails or screws, no the whole construction is loose and hold together by its own weight.
