Now I need to lock the mechanism in a neutral position before attaching some balancing weights to the other side of the wheel so that the assembly is balanced what ever position the wheel is in. The plan is then to release the mechanism and see what happens. According to Bessler one 'cross bar' hardly moved the wheel, but what does that mean? Does he mean that he had to nudge the wheel a little to complete a full turn, or does he mean that it turned but extremely slowly? I can't somehow believe that the wheel would turn slowly and evenly, but I suspect that it managed most of one turn and then needed a small nudge. The thing is, how convincing would that be? It must have been enough to convince Bessler that he was on to something, so I guess I'll just have to try it and see. I suspect that in the end I'll have to put more mechanisms on. I might of course be completely wrong - again - and perhaps what most people are telling me is true, that parametric oscillation is not the answer. Only they'll have a job to convince me!
I'm going to be away for a couple of weeks starting next week- Spain again! - so I'll close comments early next week and go into silent mode for fortnight. I'm hoping to finish this latest mechanism before I go, but I think my wife has other plans for the next couple of days so I probably won't be placing any updates on it before I go!
