   Here are some thoughts.
      I have completed some crude tennis ball testing, they are about 60% efficient and at 150 rpm on a 6 foot wheel the ball will rise 12 to 15 feet above the contact point.

Hi Dale,
interesting concept.
Was this a typo or how high did the tennis ball rise when they are making contact with the lower
ramps ?

So does this only work at an optimal speed , so the centrifugal forces will help it ?

Many thanks.

   Hello,
    The tennis ball testing was just releasing a tennis ball at rpm from a 3 foot lever on to a solid table about 10 inches below, I filmed this to see if and how fast the ball would return. At about 75 rpm the ball after contact rises faster than the lever that released it. at 150 rpm it is very much faster and will rise many (8 to 10 feet) above the table. When I drop a tennis ball it bounces about 60% of the released hight. I tried a super ball, they claim 90% that got pretty exciting, it bounced better but was uncontrolable.  I think this will be very rpm sensitive but with centrifugal force increasing on the square of rotational speed I think that there will be a window it will run in and I am guessing somewhere on the low end of 75 and maybe 180 to 200 top side.
   Thanks

    Hello Stefan
   I repeated some of the crude tennis ball testing yesterday, This time the ball was only about 40% (it is 40 degrees here now) It required 100 rpm on a three foot lever releasing to a platform 6 inches below to make the ball rise faster than the lever. The ball passed the lever that released it on the up side right before the 90 degree point.
    I have been focused on the timing between the release point and when it catches or passes the lever on the up side rather than the total height that the ball rises, however at 100rpm the ball climbed just a little over 9 feet above the impact area or 3 feet over the wheel.
  I hope that answers the question a little better.
   I have started a small prototype and have the axle, bearings and center hub complete for a 5 foot wheel.
    I would love the thoughts, advice,and counsel of the greater minds here.
   (thats a cry for help!)  :)
    Thanks
   Dale

Hi Dale,
can you post a few more (hand written, are okay) drawings ,
what you are exactly doing ?
It is not yet clear to me, what you really want to achieve.
Do you try to state, that the lower lever arm is able to push the ball
up into the direction of the axis with more more force or
does the tennis ball jump just by itsself higher up ?
Maybe you can also post a small video, if you have a videocam.
Many thanks.
