Update - and five mechanisms required for proof of principle
Because I remain convinced that parametric oscillation (or kiiking) is the key to understanding Bessler's wheel I hope those who read this will understand why I continue to discuss it here.
Following a suggestion by a member of BW forum, I reconstructed my wheel with one (modified) mechanism instead of five, in an attempt to provide proof of the principle. I then realised that I had set it up wrongly as I had included an equal weight on the opposite side of the wheel to counterbalance it. This of course reduced the torque available to a very small amount. A kiiking rider has only himself to rotate about the swing pivot but if he had a non-participating second rider attached on the other end of a pair of extended swing rods he would be counterbalanced either in his outer position or in his inner one, depending on how the counterbalance was arranged. But even if the counterbalancing rider was working at pumping the swing in concert with the main rider, the torque available would be tiny in comparison to that generated by one rider.
I removed the counterbalance, restoring the full torque available and the mechanism, when started at a position close to twelve o'clock, rotated to the eleven o'clock position where it stopped and reversed. Obviously the mechanism was generating too small a pulse. This also highlighted the fact that kiiking swingers have to pump their swing many times to get up to twelve o'clock, (20 or 30 pumps) and this is clearly the only point from which they can achieve a full rotation.
The sport of "kiiking", or "kiikuda" to use the correct verb, requires the winner to be the one who can achieve a number of consecutive rotations using longer swing rods than anyone else. This implies that the rotation is easier to achieve with shorter rods - or that the distance the rider moves his body in or out is relatively more with shorter rods. Obviously the latter applies as the distance moved inwards or outwards is going to be roughly the same for every contestant (unless he or she has extremely long legs!) but is more effective on shorter rods.
As my mechanism moves the weight inwards a set amount because the weights are the same regardless of how long the rods are, I may shorten the rods a small amount to increase the change in the angle of momentum and generate a stronger pulse, but space is limited. So if I place a second mechanism exactly opposite the first one, I anticipate that with the reduced torque then available from the action of the mechanism, the wheel will still not achieve one rotation - why? Because the difference in length of the pendulum achieved by the falling shifter weight, will only produce a small impulse. I stated many times and on my web site at http://www.besslerswheel.com/ that I believe that the wheel required five mechanisms as I maintain Bessler implied by his ubiquitous use of the number five,and that is still my firm opinion. Because I believe this is true I shall omit further testing with anything less than five. I'll update this information when I have more to say.
I have updated an old web site at http://www.247website.co.uk/ I occasionally post things on which have little to do with Bessler, and have added a potted history of Kiiking and good evidence that it goes back a long time before Ado Kosk publicised it.
