12 times more output than input, dual mechanical oscillation system !

Actually, I meant something much less significant that what you did there. Most clever! I'd be most interested to see such a machine, and why it does (or doesn't) work. I hope someone with the required skills will soon get to building that machine.

I was merely rambling to myself whether a restricted swinging weight in some way could be used to get more "gravity pull". Likely not, or at least not easily so.

My belief is that in the common 2-stage oscillator (pendulum), the gravity is only aiding in the creation of an oscillation, like a capacitor and a coil makes an LC tank.
In my 'upgrade', I does away with gravity, and since it is the centripetal force we are tapping, weight will no longer be an issue. Since centrifugal and centripetal force increases by the square of its angular velocity, simply allowing it to rotate faster will make the output larger, so we do not need any more weight in the pendulum (or unbalanced wheel).
The only case where we would maybe have needed a larger weight would be when we wanted a lower rpm, but still a lot of power.

I have plans of making that thing some time in the future when my welding skills gets better
Btw, after seeing some machine related on the energetic forum, I found that an extremely simple version of the machine on my homepage can be made to instead use water.
Since the pressure of the water will increase with an increased rotation, you could make something resembling a centrifugal pump which uses the high pressure water to further aid its rotation, by using small jet-like outlets which pushes in the same direction as the rotation.
This could be little like Schaubergers machines, where only a start motor was needed in other to create a self driven vortex-pump.

At least to me the concept seems very possible....

When I see him driving a pump (resistance)  would it then not be very easy to create something like the attached drawing?

I'm sure i'm overlooking something... because it can not be that simple....

Yep, it could be that easy, but through that design an many other you get a lot of losses, especially because of your cranks. In a machine very similar I am using a weight in a spring instead of a pendulum, and will try to use a nylon tread in order to take some of the output and send it back to the weight. And a spring is more easy to handle since it only goes up and down.
Adjusting the tightness the tread is will decide when it pulls and when it releases.

The biggest problem is getting the timing right, that goes also for your approach.
But build it, then we can see if it actually is possible to send the energy back.
I believe the answer to that question is yes, but a proof of concept would be very satisfying....

Tnx.

Hmm I might try that...  (Just thinking what toys of my children i can demolish for this ;-) )

If started from pendulum....
If I mess around with the counterweight initially - I can make the pendulum swing even from the output. (but this is probably lots of _work_)
There is no mechanical "diode" or ratchet which decouples both oscillations.
If the stuff works on it´s own - you can´t say that one part drives the other.
Its one piece.

I am not an engineer, I do not have math skills, but I do have
a hands on working knowledge of this device.

The basic principle is very simple. When a pendulum bob swings up it loses weight as compared to the rest state. When it swings down it gains weight as compared to the rest state.

It is a fact of life. You can prove it mathematically or you can experience it directly. Take a 5 Kg weight in your hand and swing it in a half circle. As it swings up level it "appears" to be weightless, yet when it swings down it becomes very heavy.

This is it! the weight change appears at the pivot point!

Now take a one meter long arm and attach an 18 Kg  pendulum to one end with the fulcrum at the 500 mm mark. You must press down on the free end with a force of 18 Kg to bring the arm level. But you are doing no work.

Now, have your assistant operate the pendulum. Note that when the bob is at the peak of its swing you only have to push down with a force of 9 Kg to keep the arm level. When the bob swings down you really have to push down hard... 27 Kg hard... you are doing work... and you are doing work at a far greater rate than your assistant.

Now when you get smart you could just hang an 18 Kg weight on your end of the arm and step back... note now the weight is doing the work. But in doing so, the arm if still free to move will oscillate up and down, permitting even addition work to be preformed.

To reiterate, a pendulum bob in motion suffers a weight change. This weight change is present at the pivot. Connecting this to an arm transfers this weight change to the opposite end of the arm inversely, in accordance with the law of the lever. Once you understand this reading my document
should make more sense. There are links in the document to my video and sources.
