CG Showcase of Overbalanced Wheel

a wheel model using 2 full curve

yap, that design does give mi problem, so revert back to traditional design.

  helloha, this is something that some of us have wondered about. If the balls
could roll from the inner curve of the wheel to the other side on it's outer curve.
Then after rotating the wheel, it rolls back to the other side of the wheel and up
it's inner curve again. It might take a ramp next to the wheel for the bearing to
roll on, but the lift and drop would be close, and the ball on the outer curve
would have more leverage.

edited to add; helloha, do you think you could have the parts where the arrows pointed roated
a little bit in those directions ? Basically, just showing the curved part touching the outer wheel and the
weight and it's lever dropping a little.

Isn't the idea the sjack abeling wheel? Jim, u bad bad, i visualize myself getting into trouble, NOOOO.....

anyway, about the ball rolling onto the ramp, u can take reference from past cg i done here

timing is the issue, the ball either will roll to ramp early or late, but never what i expect, and landing on the other side.......sign 

but i will be implementing the ramp idea to the rollback wheel, just need to think alot, and trial and error alotttt, but lets take a break first.

The CG in the photos in post 31 seems like it would be below the axle. Great mechanics but bad CG so it probably bottom heavy.

  I swear you are a magician helloha. I have done a lot of trial and error myself. Half the fun is trying something.
@Norman, the idea is to pump water with these mechanics. When the weighted lever closes the bottom of the curved pump, water is moved upwards. While helloha shows the pump closed, depending on the placement of the short lever, that could be how it works. And that is a detail that might take some trial and error to learn the proper placement of the short levers.

   helloha,
What might be a thought is something close to what you have been trying.
If 4 weights are on the over balanced side and 3 are in the inner under balanced side, there might be a way to get it to work (or almost).
The 4 weights on the over balanced side would be on a round cylinder like what you have been trying, They can be spaced going deeper into the wheel and as the wheel rotates, they move towards the front and a ramp.
When they roll into the inner circle or wheel, there are grooves like the threads on a  bolt that push them up a ramp going deeper into the wheel.
This would allow for more weights working than being lifted, in theory anyway.
