Gravity Wheel concept

[Freezer]

Greetings Freezer

Here is a couple of suggestions on an approach.

For an overbalance wheel you don't need to leave the larger magnets under the effects of the other magnets as long as shown. This way you may be able to free up some movement once you pass the horizontal marks. In another term quarter your wheel off and keep your magnets in only 2 of the quarters.

Yes, I think I do need to trim it a bit.  I also might add some magnets in attraction mode to give lift. 

Here's a progression.  I put beaing inside the weights to have less friction.
