Hi grim,

You stated in part, "...that he felt was necessary to disguise with noisemakers..."

I've heard this arguement before, that Bessler employed noise making weights to disguise more subtle noises coming from within the wheel. The problem with this hypothesis is that noise making weights at the wheel rim would have been immobilised under the high centrifugal force generated by the 9 foot diameter 50RPM Draschwitz wheel.

Also, at maximum speed the Draschwitz wheel rim was moving faster than a weight will fall under G acceleration. IMO, any free to move weight at the rim of the Draschwitz wheel would be immobilised and silent at the reported maximim speed.

Good luck with your construction.

: : Bessler stated that, during demonstrations, he would allow his wheel to be pushed or turned in any manner desired, stipulating only that the wheel must not be forced to rotate faster than the maximum speed for which it was designed.

: : That being so, Bessler would have had no objection to someone turning his uni-direction wheel in reverse for as long as they liked.

: : This raises a couple of questions: 1) Did the uni-direction wheel exhibit an overbalancing force when rotated in reverse? 2) Did the uni-direction wheel exhibit rim impact noise when rotated in reverse?

: : IMO, if the later bi-direction wheels were composed of two joined back-to-back uni-direction wheels then, IMO, the one-direction design must have been silent when operated in reverse, otherwise the bi-direction wheels would have exhibited rim impact noise on both sides of the wheel.

: : Furthermore, if the overbalancing force acting on the wheel was accompanied by unavoidable rim impact noise (Bessler said he couldn't silence the noise) then, IMO, the uni-direction wheel exhibited no torque (was balanced) when turned backwards. No noise = no torque.

: : Question for those presently building wheel attempts: Can your design be turned in reverse without problems?
