Maybe Karl described the simplicity of the concept, and not the wheel itself.

I suppose I should mention this on the Besslerwheel form but it doesn't seem to warrant a new thread; it's just my musings again.

When Karl's emissary, Nathaniel von Stapff, first approached Bessler with a view to checking out his claims, he must have made it clear to Bessler that in order to take advantage of the Landgrave's patronage, he would be required to reveal the secret, under an oath of silence of course, of the wheel's construction. Clearly this was a highly contentious issue for Bessler and yet he was persuaded to accept, the issue molified to some extent by the promise of 4000 thalers for the privilege.

So before Karl could even consider such a proposal he had to verify to his own satisfaction that Bessler's wheel actually worked, and since the Kassel wheel would not be finished for several months, and the previous, Merseberg wheel, had been destroyed, the wheel Karl saw must have been the small model mentioned two or three times elsewhere.

This small model may have been Bessler's first fully working model or even one which showed some rotation without providing enough to drive another device and it could only turn one way. It may have been the same one that was found in pieces after his death, and the same one that Jean-Pierre de Crousaz wrote somewaht sarcastically about. So when Karl described its simplicity he was probably describing the basic concept and not the interior of the Kassel wheel.

It is evident that Karl was heavily involved with matters of State and probably never took time to view the interior of the larger wheel, so one might conclude that although the concept appeared extremely simple to Karl, as he examined the model wheel - and that idea was born out by Bessler's own fears that any potential buyer might think he deserved his money back once he knew the secret, in fact the actual working model might have been considerably more complicated.

By complicated I mean that, whereas I have always maintained that Bessler indicated that five mechanisms were necessary to a fully functioning wheel, there might have been as few as two in his model version - a very simple concept and an ideal method of constructing a proof of principle version.
