For this condition to be present the weight which fell and overbalanced the wheel, must have also reversed the action of the preceding weight. In other words it created a condition of imbalance when it fell, thus prolonging the overbalancing effect permanently.
Although the chances of creating a mechanism which effectively achieve the action described in the paragraph above, seem vanishingly small after 300 years of trying, I am confident that this solution will be found. I can’t say unequivocally that it has been found because I don’t have a working model yet, but I am aware of the specific Bessler clues which demonstrate how Bessler did it.
One more thing; the mechanism was described as simple, well it may look simple to understand, but it isn’t so easy to build. Each mechanism, of which there five - and there is no doubt about that - consists of ten separate pieces metal, plus two weights. There are no springs and there is nothing odd about the weights, so I think the weights which Bessler allowed to be examined were wrapped a handkerchief for two reasons, firstly they were greasy and secondly it added to the mystique surrounding the whole event. Mine are simple lead discs with a hole through the centre. I can put several on one bolt to produce the desired weight.
